Amino-acids are responsible for the basic constitution of proteins. Therefore they allow the construction of every cells in the human body.

What are proteins used for?

Proteins are found in muscles, enzymes, hormones, blood cells, antibodies, bones, skin...
They are mainly used to build and repair tissues, to regulate vital functions (growth, reproduction, glucose level, digestion...), to allow muscles to contract etc.

Some amino-acids can be synthesized by the human body "essential amino acids" (tryptophan, methionine, lysine) and others called "semi-essential" such as arginine and histidine, will be synthesized by the liver, thanks to the essential ones. Finally, some are not involved in protein synthesis but have recognized physiological functions such as carnitine or taurine.
