Valine is one of the eight essential amino acids in human body, which can be synthesized from isobutyraldehyde. It is a white crystalline or crystalline powder, soluble in water and almost insoluble in ethanol.
Valine is one of the 20 amino acids that make up proteins, chemically named 2-amino-3-methylbutyric acid, which belongs to the branched chain amino acid, is also an essential 8 amino acids and glycogenetic amino acids for the human body, it works together with two other high concentration amino acids (isoleucine and leucine) to promote normal growth of the body, repair tissues, regulate blood sugar, and provide needed energy. During intense physical activity, valine can give muscles extra energy to produce glucose to prevent muscle weakness. It also helps remove excess nitrogen (potential toxins) from the liver and transport nitrogen needed by the body to various parts. [4]
