Document Summary
Amino acid structure, ionization, primary and secondary protein structure. C is the alpha carbon with the variable side chain. The solid forms have nh2 and cooh (know this, she will ask a question like this on a. In water: the nh2 becomes nh3 (+) and the carboxyl group becomes coo (-). test) Methionine has a sulfur more en than carbon, so there is polarity in the sidechain, but apparently not enough to make it polar. Tyrosine looks mostly non-polar, but the hydroxyl makes it polar. Glycine has a hydrogen as the side chain it can rotate a lot, which makes it special. Proline the r group turns and binds back to the n of the amino group forms a ring structure. It"s the only amino acid that does that it causes it to be structurally very restrictive causes kinks or breaks in the alpha helices it is a part of. Cysteine is the other amino acid that has a sulfur.
