What function do amino acids perform in the body?
Amino acids are molecules that contain a carboxyl group; as components of proteins
, they play a critical role in metabolism, and structure and function of cells. There are around 500 known amino acids but only around 20 build proteins. Nine of these are termed ‘essential’ since they cannot be produced by the body and must be ingested from the diet. Other amino acids (notably arginine and cysteine) may also be considered ‘essential’, depending on an individual’s age, state of health or diet.
Amino acids can also be important biosynthesis precursors and play a crucial role in the physiology of many processes related to health (sleep, fertility, physical activity, muscle-building ...). That is why they are so widely used in dietary supplements.
Most of the natural amino acids in the human body have a levorotary structure which is why many have an ‘L’ in front of their name (l-carnitine or l-tryptophan for example) as opposed to a ‘D’ which signifies a dextrorotary structure. The molecules offered by Supersmart (sulphur-containing amino acids, branched-chain amino acids (BCAAs), proline, carnitine …) are all natural-source.
