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 |
| Isoleucine | C6H13NO2 | 131.17 g/mol |
| Leucine | C6H13NO2 | 131.17 g/mol |
| Lysine | C6H14N2O2 | 146.19 g/mol |
| Methionine | C5H11NO2S | 149.21 g/mol |
| Phenylalanine | C9H11NO2 | 165.19 g/mol |

| Tryptophan | C11H12N2O2 | 204.23 g/mol |
| Valine | C5H11NO2 | 117.151 g/mol |
Conditional amino acids formula
Conditional amino acids are required only when you fall sick, or stressed or injured.
| Types of conditional amino acids | Chemical formula | Molecular weight |
| Arginine | C6H14N4O2 | 174.2 g/mol |
