85-1336-18　L-Serine (L-Ser-OH) 2.5Kg　CAS No:56-45-1　S1000

特徴

• Serine (abbreviated as Ser or S)[3] encoded by the codons UCU, UCC, UCA, UCG, AGU and AGC is an ɑ-amino acid that is used in the biosynthesis of proteins. It contains an α-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 hydroxymethyl group (see hydroxyl), 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.
