Side chain of tryptophan

WebTryptophan, phenylalanine, and tyrosine. Tryptophan (Trp, W) has a double ring that contains a nitrogen atom. The side chain of Phenylalanine (Phe, F) is a benzyl (benzene rings and an additional CH 2 group) while adding an OH group to phenylalanine makes Tyrosine (Tyr, Y). The OH group also make tyrosine polar. WebThe arginine side chain is very basic because its positive charge is stabilized by resonance. The two nitrogens of the histidine side chain have a relatively weak affinity for an H + and are only partly positive at neutral pH. Table 2: Charge of the amino acid side chains. Only the side chains are shown.

There are three amino acids that have basic side chains at neutral pH. These are arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base. Their pKa's are high enough that they tend to bind protons, gaining a positive charge in the process. green casual sneakers
