Amino acids testing expertise
Vitac Pharmaceutical Canada routinely perform amino acid tests, the quantification can be done on pure samples as for the standardization, or as amino acids included in different matrixes.
Amino acids classification
Chemical structure of Amino acids (AA) contains amino and acid groups, with one exception for glycine, all AA have an asymmetric carbon and exhibit optical activity.
Because of variations in their side chains, AA have remarkably different biochemical properties and functions, as a result remarkable variation in biochemical properties.
Amino acids importance in the metabolism
Recent research on the role of amino acids (AA) in the body metabolism highlighted their importance and key functions as regulators, hormones precursors and building blocks of proteins, therefore they are categorized as essential, and non-essential. Among 20 different amino acids identified and characterized, only nine amino acids are classified as essential.
| Essential Amino Acids | Non-essential amino acids |
| L-Histidine | L-Alanine |
| L-Isoleucine | L-Arginine |
| L-Leucine | L-Aspartic acid |
| L- Lysine | Glycine |
| L-Methionine | L-Proline |
| L-Threonine | L-Serine |
| L-Tryptophan | L-Tyrosine |
| L-Valine | L-Cysteine |
| L-Phenylalanine | L-Glutamic acid |
