WebIt's hydrophilic, due to the hydroxyl functional group in the R group. Though the R group also contains a hydrocarbon group, the hydroxyl group is outermost and thus determines … WebHuman serine racemase (hSR) is a pyridoxal-5′-phosphate (PLP)-dependent dimer that catalyzes the formation of D-serine from L-serine, as well as the dehydration of both L- and D-serine to pyruvate and ammonia. As D-serine is a co-agonist of N-methyl-D-aspartate receptors (NMDARs), hSR is a key enzyme in glutamatergic neurotransmission. hSR …

Web10 Sep 1999 · The differences between disulfide-bonding cystine (Cys_SS) and free cysteine (Cys_SH) residues were examined by analyzing the statistical distribution of both types of residue in proteins of known structure. Surprisingly, Cys_SH residues display stronger hydrophobicity than Cys_SS residues. A detail … WebAmino acids with nonpolar substituents are said to be hydrophobic(water-hating). form hydrogen bonds to water are classified as hydrophilic(water-loving). The remaining amino acids have substituents that carry either negative or positive charges in aqueous solution at neutral pH and are therefore strongly hydrophilic.
