L-asparagine is a key α-amino acid that is used in the biosynthesis of proteins. It contains a α-amino group and a α-carboxylic acid group as well as a side chain carboxamide. It is classified as a polar [at physiological pH], aliphatic amino acid. It is non-essential in humans, and can undergo de novo synthesis inside the human body. From the aspect of genetic code during protein synthesis, it is encoded by the codons AAU and AAC.
L-asparagine is a chemical, the CSA number is 70-47-3, and the chemical formula is C4H8N2O3. It is one of the 20 amino acids commonly found in living organisms. It was isolated from the water extract of lupine with high content of L-asparagine and bean sprout of soybean. It is prepared by amidation of L-aspartic acid with ammonium hydroxide.
