- Professor Fink first describes the molecular structure of steroids, the sources of Cholesterol in our diet, and the mechanism of action of Lipitor (& other "statin" drugs). Following this, Professor Fink reviews the Androgens (including Testosterone & Adrenal Androgen; DHEA), Estrogen & Progesterone, the Mineralocorticosteroids (like Aldosterone), the Glucocorticosteroids (like Cortisol), and Cholecalciferol (Vit D).

Dear Professor Fink, I sincerely don't know how I could have survived some of my exams in med school without your videos! Thank you very much for making them available. Your are a gifted lecturer.
I took physio in high school and anatomy last year in college and I’m about to take college physio this summer. I’m watching these videos to refresh my memory and get ahead since it’s a 6 week class. My goal is to get through all of them before my class starts next month Prof. Fink really is great!
Professor Fink. I normally do not comment on youtube videos but I had to say thank you for these amazing lectures. I already have a Masters in Pharmacy so watching these videos is revision and a refresher for me. In fact, I watch your lectures during my dinner time instead of TV.
Thank you very much
OMG me too! wow exactly the same haha👍🏻
Professor, Fink, you're just brilliant. I have watched hours of your lectures, and you are so informative. You can take a complex subject matter and break it down for easier understanding. THANK YOU!! Please keep them coming.
Regarding Cholesterol: while further research on the causes and mechanisms of atherosclerosis continue, there is still OVERWHELMING consensus that dietary intake of saturated fats & cholesterol IS a factor (genetics & other possible environmental factors not withstanding). You can refer to the AMA, MAYO CLINIC ("aim for no more than 300 mg of cholesterol a day") and AMERICAN HEART ASSOCN web-sites.
What a great explanation! Thank you very much professor 💙
High Cholesterol is GOOD for overall health. www.nature.com/articles/s41598-018-38461-y?fbclid=IwAR14vO6hbQ4xFscFdn8pCVXrTl-XRW2wearxeTtCVjSwBgSNTldxztTBfOk
If the recommendation for cholesterol intake is 300 mg a day then that would mean a human can only consume 2 eggs a day? Incorrect.
Yes eggs are high in cholesterol but the liver doesn’t digest and the body doesn’t absorb all the cholesterol especially from eggs, according to some studies a person can consume up to 30 eggs a day and not suffer from elevated cholesterol levels, what should definitely be avoided instead of eggs is refined carbs,sugars,trans fats and processed foods that elevate oxidation in LDL cholesterol.
@@terminatorjuice3310I agree, I work as a weight loss coach, and all we give our clients to eat are natural saturated fats and first class proteins, green veggies and tell them to avoid all carbs. Successfully reveresed cholesterol, high BP, type two diabetes, pcod, pcos in a matter of 1 to 4 months along with tremendous weightloss.
I wonder how scientific community got it so wrong abt natural sat. fats and claiming it as poison for bp, cholesterol patients and not carbs!!!!!!
You are a great professor. I love your analogies!
I am an engineering major and was never into biology related courses until I watched professors Fink's lectures.....
Best videos ever! You are a fantastic teacher. Thank you for facilitating my learning during PA school!
I just love your videos so much, thank you!
I want to think like professor Fink, he is amazing!
THANK YOU SO MUCH PROFESSOR FINK
Dear Prof Fink, Thank you very much for uploading such type of informative video lecture. I learn a lot from your lecture which is very helpful for teaching my student.
Thank you 🙏 professor! You are a true educator!
Professor Fink, Thank you for your lectures and dedication to education. I'm particularly interested in learning more about the hormonal pathway of cholesterol to testosterone. Can you refer me to any literature that can help me learn about any relationship between cholesterol and testosterone?
In the meanwhile, I've read that Keye's Lipid Hypothesis included skewed data, and only exhibited countries with high cholesterol and high incidence of cardiac arrest. Some doctors believe that high blood sugar causes inflammation within arteries, which results in plaque buildup to help the artery heal. What is your opinion regarding these studies and theories?
I look forward to hearing from you Dr., thank you for your time and have a great weekend.
Yeah science! Yeah Mr. Fink!
One of the great quality of human mind is to get information, reprocess it further and pass it to other in better form like a wave modulator.
Undoubtedly, your brain is great in this regards.
I sincerely appreciate and salute your great knowledge and great teaching skills. You are a great Guru like an enlightened sage.
Thank you sir 🙏
What a beautiful metaphor! Thank You for your kind words. And Best Wishes for your Success!
@@professorfink 🙏
you are the best of all the time teacher
Thank you
So amazing
this is the second time i watched this video today glad i did to because i was wondering why the body cant make cholotereral from unsaturated vegetable oils but i just missed part of the video the first time i guess. thanks for uploading!
alhamdulilah I found your videos! they are literally saving me, haha god bless!!
What did u understand bro? I’m high on cholesterol and took anabolic steroids in the past
i don't like science but this the is good deam i get everything , very good teacher
Correction we do not need sugar we need glycogen which can be made from carbohydrates and even so can be found in other sources, sugar is not necessary nor required for optimal growth or homeostasis
Dr.Fink !
Thank you for your great way of teaching ,I just wonder if all the lecture notes shown in the Video are availabe in the
e-book and if yes, which E-book?
Thank you.

Dr. Fink. would you please comment on the relatively recent idea that cholesterol actually does NOT contribute to CHD or Atherosclerosis?
+J Gerbode-Grant Please see my comments BELOW in response to "haradin1337 " 1 year ago.
+J Gerbode-Grant the statin drug companies have these studies and biased research to make
you believe that cholesterol is the problem for brain disease so they
will have the medical community convinced so they can prescribe there
drugs for a bunch of more diseases. when cholesterol and fat have
nothing to do with it. a lot of easy to find documentation on the
subject. But once you convince the simpleton that blindy agree with
statistics and blindy follow the media you have another billion dollar
quarter. your brain needs cholesterol and fat. lower cholesterol will
lead to low vitamin D as well, which is a huge problem in america and
low vitamin d will lead to lesions in the brain. you will break down
your myelin earlier if you do not supply your brain with cholesterol and
EFAs. it is very scary that educated doctors are feeding us lies but
also that they believe them! our diet is more low fat and low
cholesterol than ever yet brain disease keeps rising, along with
diabetes and obesity. you need to get your brain to run on ketone bodies
eat high fat, medium protein, and low carb (dark green veggies). This
is type 3 diabletes, our brain metabolism is failing to metabolize
glucose and with any signs of brain disease you need to switch to a
ketogenic diet asap and get off any statin drugs.
I love your videos professor
from iraq with love
Professing at its finest!
Dear professor Link when you combine cholesterol with sugar or high levels of glucose you damage the overall value of cholesterol and mutate it's effect. LDL especially in this case which becomes harden or damaged.
Hello there, thank you very much sir for your interesting lectures,
since i'm a biochemistry student
i have a little intervention about cholesterol synthesis:
actually it's not synthesized using saturated fatty acid chains, as you mentioned in this lecture, but it's a result of an assembly of acetyl-coa molecules using different enzymes . i just wanted to make things clear. Thanks again sir
You are quite right; in other lectures covering Metabolism, I describe how acetyl-CoA sugars can be joined together to form saturated fatty acids, or reversibly broken back apart into acetyl-CoA (reverse beta-oxidation reaction). The emphasis of this course is physiology and not biochemistry. -- prof. fink
@@professorfink I'm not a physiology student, but I'm really interested in learning it since biochemistry and this field has lot of notions in common... Another motivation is that i loved your way of explanation.
If you don't mind sir, i have some Questions that i didn't find answers for in biology.
I'd love to discuss them with you as great teacher in biology domain. Have blessed day sir
Professor fink! I love your videos watched quite a few of them. But i feel i have to comment on something. The lipid abd cholesterol hypothesis have been disproven time and time again. It is commom knowledge that dietary cholesterol does not raise blood cholesterol. Could you please make a note on this at it is a pretty big issue in my opinion. Thanks again for the vids. M
Thank you for your kind words about the Videos! I sincerely appreciate it.
Regarding Cholesterol: while further research on the causes and mechanisms of atherosclerosis continue, there is still OVERWHELMING consensus that dietary intake of saturated fats & cholesterol IS a factor (genetics & other possible environmental factors not withstanding).

What was the sentence you used prof Fink to remember and differentiate between LDL and HDL ?
pleaseee
Use this: Healthy HDL and Lethal LDL. (What I said in the Video was "low-down dirty LDL" and "High, Upright HDL")
@@professorfink thank you Profesor. How are you btw ? no one ever asks you this question on CZcams. Any future plans ? Any new videos ? Why don't you do a video with Armando H, check his videos on CZcams they are good. :)
@@wassimabdou7649 I also enjoy watching the videos by Armando Hasudungan; his videos are more aimed for medical students, while mine are aimed for allied health students.
hello Dr. Fink,
As you said in this video, if steroids only come from animals, how do vegetarians get steroids? If they even don't eat eggs. Can human body make steroids? thank you.
The Liver cells have enzymes (incl. HMG CoA Reductase) that can convert saturated fatty acids (small amounts of which are found in vegetable oils) into cholesterol. In fact, the statin drugs (such as Lipitor) work by inhibiting this enzyme.
He mentioned that can synthesized cholesterol. In fact, it makes more than enough, so strict vegetarians do not need to eat animal products to ensure adequate amounts of cholesterol.
+Han Ly Body can synthesize cholesterol.
The best professor ever.

very nice lectures may Allah blase you sir
Thank you.
So many medical myths and unsubstantiated theories presented as fact. For example higher metabolism of males is responsible for decreased longevity compared to women is presented as fact. There are so many other factors involved and the jury is still out. For example, Progesterone and saturated fat corresponds to longevity in females and in tropical birds. Higher metabolism can be attributed to longevity in many species and in humans is necessary for healthspan...who wants to live forever suffering from poor energy reserves? Good luck to you all in medical school but take all these 'lessons' as theory and not fact.
