Amino Acids - 101

Below is a picture of the amino acid drawing I learned in biochem a few years ago.  By using this method, and repeating the drawing until I could do from memory, biochem became easy.

Notice the purple outline indicates what changed between the molecules.  For the most part after Leucine, CH2 is a part of every amino acid so the backbone becomes the one with the CH2.

PLEASE NOTE: As of 8/23/15, this HAS been updated for the extra CH2 off the backbone.


If you're wondering WHY draw?  From the best biochem professor ever:

Fyi you drew histidine wrong. You need another CH2 connecting it to the backbone.

Thank you, David!

I'd been told this and had not uploaded the revised picture. I apologize!
