L-Alanine CAS 56-41-7

L-Alanine is white crystal or crystalline powder, no peculiar smell, with sweet taste. It is easily soluble in water (16.5%, 25℃), insoluble in ether or acetone. The decomposition temperature is 297℃>, mp233℃, isoelectric point 5.79, pka-COOH=2.34, Pka-NH3=9.60, [α]25D+14.6 (C=0.5～2.0g/ml, 5mol/LHCl). L-Alanine is a non-essential amino acid for the human body, which is formed by transferring the amino group of glycine to pyruvate in the body. In the glucose-alanine cycle, it keeps the blood ammonia level low. Alanine is an excellent transporter of nitrogen in the blood. It is also an effective amino acid for sugar production.
