What is Collagens (CAS: 9007-34-5)?

Collagens are a family of naturally occurring fibrous proteins, which are the principal structural proteins in animals. They are composed primarily of the amino acids glycine, proline, and hydroxyproline. Collagens are the most abundant proteins in mammals, accounting for approximately 25%–35% of total protein content. They are known for their strength and flexibility, making them essential for various biological functions such as skin, bone, and cartilage structure. Collagens are characterized by a triple helix structure and are found in various forms and types (I-XVIII).
