L-Serine

Serine (abbreviated as Ser or S)[3] encoded by the codons UCU, UCC, UCA, UCG, AGU and AGC is an ?-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 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. Synonyms: L-Ser-OH, (-)-Serine, (S)-2-Amino-3-hydroxypropanoic Acid, (S)-Serine, (S)-alpha-Amino-beta-hydroxypropionic Acid, 1: PN: US20090069547 PAGE: 10 claimed protein, 225: PN: EP2071334 SEQID: 242 claimed protein, 225: PN: WO2009077864 SEQID: 242 claimed protein, 6: PN: WO2012061268 SEQID: 6 claimed protein, L-(-)-Serine, L-3-Hydroxy-2-aminopropionic Acid, 3-Hydroxy-L-alanine, L-Ser, beta-Hydroxy-L-alanine, CAS No: 56-45-1, Molecular Formula: C3H7NO3, Molecular Weight: 105.09, Appearance: White crystalline powder, Purity: >98%, Melting Point: 222°C (dec), Identification: Conform to USP, Important Note: This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological.
