The amino-acid content of Peptan™ is similar to the one of native collagen, thanks to Rousselot’s careful and moderate hydrolysis.

Peptan™ contain all essential amino-acids except tryptophan and is characterized by the predominance of glycine, proline and hydroxyproline which represent around 50% of the total amino-acid content.
This very specific composition of amino-acids provides hydrolyzed collagen with nutri-functional properties which cannot be found with other protein sources.

As can be seen in the table below, the variation of amino-acids compositions depending on the specie of the raw material is quite minimal. The main difference is found for hydroxyproline, present at a lower content in the fish Hydrolyzed Collagen.
