You're welcome, and sorry for the late reply. Disulfide bonds very rarely form in the cytosol. Their virtual absence can be attributed to the reducing environment. However, in rare instances, they are formed for reasons not linked to normal protein activity. For example, some viruses can be responsible for disulfide formation.
@@Leah4sciMCAT I guess this question you can answer. 👏🏼 interestingly, this question IS directly in relation to MCAT testing. At least be consistent lady.
Yes, it is possible to have stabilization by disulfide bonds in both tertiary and quaternary structures. Tertiary and quaternary protein structures are held together by the same weak side chain interactions. The only difference is that quaternary protein structures are defined by the interactions of more than one amino acid chain. Hope this helps!

@@Leah4sciMCAT no one is asking to be tutored. I asked a simple question. Yes or no is not going to help me pass or fail the MCAT even if I was taking it.
@@clintmurphy72 yeah, no one has been able to definitively answer this question. It also seems that no one knows what I’m talking about. I refuse to speak and share the implication of this info until it’s verified, no matter how much I want it to be true.
You would need to begin the Strecker synthesis with the appropriate side chain on an aldehyde. Take a look at my video on the Strecker synthesis of amino acids here: leah4sci.com/strecker

Love how you explain things! Reviewing my MCAT prep questions, I always pull up your videos when I don't understand a concept
Awesome! Thank you, I'm so glad it's helping you!
Thank you for your video. After endless hours of browsing for answers, you were the only who was able to make everything super clear!!!
Glad I could help and thank you so much for the kind words
Wow I actually understand Di sulfide bonds now.Thank you !
YAY! You're very welcome!
Excellent explanation you've done here, ma'am! 👍👌
Thank you! 😃Glad it was helpful!
thank you for your help and making it easy.
You are so welcome!
Very well explained. Thanks!
Glad it was helpful and you're so welcome!
Beautiful, I love this oxidation reaction, LEO the lion grrrrhhh lol, I love it!
You're very welcome David. Memorable mnemonics makes it easier to learn and remember. Glad you like it
Such a great video, really thank you so much..
You're very welcome!
It's cleared my problem.
Awesome!
Fantastic thank you
You're welcome!
I love you!!!!
Awww thanks!

Thank you!
why are disulfide bridges found in cytosol(reducing environment)? Thank you!

Hi. Would you know why people who can’t eat sulfur foods have reaction to B6 vitamine as well?
I have no idea! If you have any questions specific to this video, I'd be happy to help. :)
Please tell me is there disulphide bridge in Quaternary Protein? In my book it is not mentioned! I can't understand it.

@@Leah4sciMCAT looks like you were on a roll answering questions directly related to MCAT!! My question has nothing to do with it.
Question…how often do these Sulfuric bridges appear? Is it true they appear every 10 acids, 5 acids, 6 acids, 5 acids and sequence repeats?

?Is this oxidation reaction reversible

Yes, it is reversible through the process of reduction.
@@laraaziz7211 can I ask you a question, off topic, since this lady only answers questions to whom she pleases?
So they're pronounced the same? whyyyyyyy
Yep! Sorry, I don't make the rules
