Keratin Specification

The Keratin is an organic compound with the formula . With the CAS registry number 68238-35-7, it is also named as Animal Keratin. The product's categories are Cell Signaling Enzymes; ECM ProteinsCytoskeleton and Extracellular Matrix; Extracellular Matrix; Extracellular Matrix Peptides and ProteinsProteins and Derivatives; Keratin; Matrix Metalloproteinases Products; Structural Proteins. Besides, it should be stored at temperature of 2 - 8 °C.

The Keratin refers to a family of fibrous structural proteins. Keratin is the key structural material making up the outer layer of human skin. It is also the key structural component of hair and nails. Keratin monomers assemble into bundles to form intermediate filaments, which are tough and insoluble and form strong unmineralized tissues found in reptiles, birds, amphibians, and mammals. The only other biological matter known to approximate the toughness of Keratinized tissue is chitin.
