Document Summary

Amino acids- an organic acid with an alpha carbon holding a carboxyl group (cooh), and amino group (nh2) and an r group. 20 standard amino acids and two addition rare special amino acids. Non standard amino acids come from standard amino acids that are modified. Zwitterion- an ion with opposite charges on different parts of it . At physiological phs, the standard amino acids are all zwitterions. (acting as both and acid and a base by the acid releasing an h+ and the base absorbing it) Nonpolar amino acids - an amino acid with a nonpolar, uncharged r group. nonpolar and uncharged. The nh2 and the cooh group might be charged, but the r group is both. Polar amino acid - an amino acid with a side chain (r-group) that is polar but. Acidic amino acid- an amino acid with an ionizing cooh (coo-) group on the r-group.
