Lysine

An essential amino acid: our body cannot make it and must get it from food. It was isolated in 1889 by the German chemist Ferdinand Drechsel from casein, the milk protein, and today it is produced by fermentation, mainly for animal feed. This family brings together the active ingredient, labelled standards and other impurities.

Did you know?In the one-letter code for proteins it is written K: L and M were already taken by leucine and methionine, so the nearest free letter in the alphabet was chosen.
