Procollagen Type I N-Terminal Peptide

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** A polypeptide comprised of the amino-terminal portions of procollagen, which are proteolytically removed during the intracellular formation of type I collagen fibrils. Increased plasma or serum concentrations of these peptides are associated with both fibrillogenesis of type I collagen and bone formation.
