Amino Acid Formula

Amino Acid formula, also known as Saltpeter formula or Nitrate of potash formula is explained in this article. They are the building blocks of life and combine to form proteins. This organic compound consists of functional groups viz amine and carboxyl along with side chain which is specific to each amino acid. The major elements are carbon, hydrogen, nitrogen, and oxygen.

Amino acid groups

Different groups of amino acids viz nonessential amino acids, essential amino acids, and conditional amino acids have been discussed along with their formula.

Non-Essential amino acids formula

Non-essential amino acids are generated in our body and it does not depend on the type of food consumed.

Types of non-essential amino acids Chemical formula Molecular weight
Alanine C3H7NO2 89.09 g/mol
Asparagine C4H8N2O3 132.12 g/mol
Aspartic acid C4H7NO4 133.11 g/mol
Glutamic acid C5H9NO4 147.13 g/mol

Essential amino acids formula

Essential amino acids are not generated in the body and you need to consume food containing essential amino acids.

Types of essential amino acids Chemical formula Molecular weight
Histidine C6H9N3O2 155.157 g/mol
