Alanine is an aliphatic amino acid, because the side-chain connected to the α-carbon atom is a methyl group (-CH 3). Alanine is the simplest α-amino acid after glycine. The methyl side-chain of alanine is non-reactive and is therefore hardly ever directly involved in protein function. [12]
For example, the systematic name of alanine is 2-aminopropanoic acid, based on the formula CH 3 −CH(NH 2)−COOH. The Commission justified this approach as follows: [7] The systematic names and formulas given refer to hypothetical forms in which amino groups are unprotonated and carboxyl groups are undissociated.
β-Alanine (beta-alanine) is a naturally occurring beta amino acid, which is an amino acid in which the amino group is attached to the β-carbon (i.e. the carbon two carbon atoms away from the carboxylate group) instead of the more usual α-carbon for alanine (α-alanine). The IUPAC name for β-alanine is 3-aminopropanoic acid.

Phenylalanine (symbol Phe or F) [3] is an essential α-amino acid with the formula C 9 H 11 NO 2.It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine.
All proteinogenic amino acids have a common structure where an α-carbon is bonded to an amino group, a carboxyl group, and a variable side chain. Only proline differs from this basic structure as its side chain is cyclical, bonding to the amino group, limiting protein chain flexibility. [ 34 ]
In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3. It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium). In IUPAC nomenclature, an acetyl group is called an ethanoyl group.
Alaninol is the organic compound with the formula CH 3 CH(NH 2)CH 2 OH. A colorless solid, the compound is classified as an amino alcohol.It can be generated by converting the carboxylic group of alanine to an alcohol with a strong reducing agent such as lithium aluminium hydride. [1]
