Ingredient: L-Proline

Proline is a proteinogenic amino acid that is used in the biosynthesis of proteins. It contains an α-amino group, an α-carboxylic acid group, and a side chain pyrrolidine, classifying it as a nonpolar, aliphatic amino acid. It is non-essential in humans, meaning the body can synthesize it from the non-essential amino acid L-glutamate.
