Function
D-Serine is an alpha-amino acid that is used in the biosynthesis of proteins. It contains an alpha-amino group (which is in the protonated −NH+3 form under biological conditions), a carboxyl group (which is in the deprotonated -COO−form in physiological conditions), and a side chain consisting of a ydroxymethyl group (seehydroxyl), classifying it as a polar amino acid. It can be synthesized in the human body under normal physiological circumstances, making it a nonessential amino acid.
