Keratin (Cynatine HNS)

{"protein": "Keratin is a fibrous structural protein, primarily composed of amino acids such as cysteine, serine, glutamic acid, glycine, and proline. It typically contains around 65-95% protein by weight.", "bioactive_compounds": {"cysteine": "Cysteine is a sulfur-containing amino acid that contributes to the strength and rigidity of keratin. It is present in high concentrations, approximately 10-14% of the amino acid composition.", "serine": "Serine is involved in the formation of keratin's secondary structure, comprising about 8-10% of the amino acid content.", "glutamic_acid": "Glutamic acid aids in the hydration and elasticity of keratin, making up around 10-12% of the amino acids.", "glycine": "Glycine contributes to the flexibility of keratin, accounting for approximately 6-8% of the amino acid profile.", "proline": "Proline helps stabilize the keratin structure, present at about 10-12% of the amino acids."}, "bioavailability": "Keratin is generally insoluble and has low bioavailability in its natural form. However, hydrolyzed keratin, such as Cynatine HNS, is processed to improve absorption and utilization in the body."}
