WebAll the amino acids have a carbon atom bound to a hydrogen atom, an amino group, a carboxylic acid group and a "side chain". The side chain is the part of the molecule where amino acids differ. With the exception of glycine and proline, the "side chain" is a chain of carbons that sticks out of the side of a polypeptide chain. WebThe reactions with these amino acids seemed to involve both the alpha-amino groups and the side chain groups, and no significant reaction appeared to occur with the side chain alone except with those of arginine, lysine, and cysteine. These reagents were similarly reactive with the guanidinium group of arginine, but PGO appeared to be much less ... WebThe two amino acids in this group are aspartic acid and glutamic acid. Each has a carboxylic acid on its side chain that gives it acidic ( proton -donating) properties. In an aqueous solution at physiological pH, all three functional groups on these amino acids will ionize, thus giving an overall charge of −1. famous gangster charged with tax evasion
