Collagen vs. Keratin: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on November 29, 2023
Collagen is a protein that provides structure and strength in skin, bones, and connective tissues, while keratin is a protein that strengthens hair, nails, and the outer layer of skin.

Key Differences

Collagen is a key structural protein found in skin, bones, and connective tissues, providing elasticity and strength. Keratin, on the other hand, is a protective protein found predominantly in hair, nails, and the outer layers of skin, providing rigidity and resilience.

The body's production of collagen decreases with age, leading to wrinkles and joint issues. In contrast, keratin production generally remains stable, but external factors can damage it, affecting hair and nail health.

Keratin

A sulfur-containing fibrous protein constituting the main structural protein of hard epidermal tissues, such as horn, hair, feathers, nails, claws, hoofs, and the like. It is an insoluble substance, and, unlike elastin, is not dissolved even by gastric or pancreatic juice. By decomposition with sulphuric acid it yields leucine and tyrosine plus various other acid-stable amino acids. The amino acid composition varies, but it usually has a high percentage of cystine, which stabilizes and insolubilizes the protein by forming intrachain linkages. A softer form of keratin is present in the epidermis and whalebone. Called also epidermose.
