Feather amino acid composition

Amino Acid Composition of Fractions from SCMK from Feather Rachis ... 

The extraction method depends on the extraction of amino acids from the acid hyrolysates of proteins. Although the method was commercialized for amino acid production (proline, serine, tyrosine, etc), the availability of raw materials like hair, feather, keratin, blood meal, etc is usually a limiting factor. Moreover, the yield of amino acids depends on the amino acid composition of the raw material. 

As can be seen from the chemical composition of down and feathers, water is an essential part of their chemical makeup. Not only is water a by-product of the polymerization of amino acids to proteins, it can also reverse this chemical reaction. Boiling water will split proteins into shorter chains of polypeptides, which is an intermediate step in the biochemical analysis of down and feathers.
