COLLAGEN
C-terminal propeptide (procollagen)/ Covalent Cross links/
C vitamin/ Connective tissue/ Cartilage/ Chondroblasts/
Copper Cofactor (Covalent Cross linking)
Outside the cell is where collagen normally functions/ Osteoblasts/
Osteogenesis imperfecta
Lysyl hydroxylase/ Lysyl oxidase (oxidatively deaminates lysyl and
hydroxylysyl residues to form collagen cross links, last biosynthesis step)
Long triple helical fibers/ Ligaments
Alpha chains/ Attached by H bonds form triple helix/ Ascorbate
for hydroxylation of lysyl and prolyl residues of pro-Alpha chains (postranslational
modification)
Gly in every third position/ Glycosylation of hydroxyl group of
hydroxylysine with Glucose and Galactose; GOlgi allows
procollagen to GO outside of cell
Extracellular matrix/ Eye (cornea, sclera)/ Ehlers-Danlos
Syndrome
N-terminal propeptide (procollagen)/ Nonhelical terminal
extensions
