Amino-acids are molecules containing an amino group, a carboxylic group and a side-chain : twenty of them are the essential building blocks of proteins. They are important in nutrition because none of them can be synthetized by the human body.

A few are not building block of proteins and very specific to plants: mimosine (mimosa), theanine (green tea), 5-hydroxy tryptophan (griffonia), S-methyl cysteine, alliin (garlic), etc …Our collection of aminoacid standards is representative of these specific "phyto-amino-acids"
