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.
