Alanine is an apolar amino acid with an aliphatic R group (-CH3), so it does not dissolve easily in water. Amino acids for protein-forming polymers that carry out many of the required functions of a cell. An aliphatic R group means that the substituent is not aromatic but has a carbon-based chain such as an alkane. The alanine side chain tends to clump together within proteins that, in turn, stabilize the internal structure of the protein through hydrophobic interactions. Hydrophobic interactions give the protein more stability and help dictate secondary, tertiary, and quaternary structure. This methyl group makes alanine one of the simplest amino acids from a molecular point of view. The methyl group rarely participates directly in enzymatic reactions. Like the twenty common amino acids, the? -Carbon is attached to the methyl substituent as well as the amino and carboxyl groups on the main backbone of the amino acid. Alanine is also ambivalent, which means that it can be found both inside and outside of the protein.
Alanine can be abbreviated with the combination of three letters Ala or with the letter A. The chemical formula is CH3CH (NH2) COOH. It is a non-essential amino acid and is produced directly by the body. It is also necessary for the metabolism of glucose, a simple carbohydrate that the body uses for energy, and tryptophan in the body. Alanine plays a key role in an important source of energy for muscle tissue, the brain, and the central nervous system. It also helps make antibodies for the immune system. Alanine plays an important role in the transfer of nitrogen from peripheral tissue to the liver in the glucose-alanine cycle.
