Amino Acids

It's time to start learning about all the monomers that make up large biomolecules, and the first one we will look at is the amino acid. These make up proteins, which is most of what you are, so this is pretty important stuff!

And I'm back again after 2 years. I passed chemistry and biochemistry because of this brilliant man!

Thank you for making a video where you SPEAK on a subject that I searched for. So many videos on amino acids are just musical power points with no narration. I don't want to sound like a dumb tool, but when I visit CZcams it isn't because I'm itching for a good read.
Much appreciated!

I didn't know any of this stuff, I take L-Phenylalanine, L-Arginine, L Ornithine and L- Lycine with Niacin, C and glycine and sometimes I do take them with a tall glass of apple cider vinager and water. Now I have to re learn everything I thought I knew. Thank you so much. I very rarely eat meats so I take these and they energize me is the main reason I take them. They also help me to think. I do drink two glasses of the acv mix so my system stays non acidic or so I thought. Thank you, again.

I was wondering why Nitrogen in the amino group has a lone pair which makes it basic. Thinking that it makes the amino acid unstable. Thank you Professor Dave, for explaining that that's how amino acids react.

[@fishcious]

Nitrogen has 4 orbitals and 5 electrons in its valence shell. Since each orbital can hold at max 2 electrons, N has one full orbital and 3 orbitals w/ 1 electron each (these are the ones that make bonds so that N 'feels like' it has a full (8 electrons) valence shell. The orbital that is already full is that lone pair and since it has a partial negative charge, that makes it slightly basic because that partial negative charge can attract and hold onto a positive H+ ion.
