Title: Collagen


1
Collagen
Collagen is the most abundant, and important,
structural protein It is the primary constituent
of connective tissue (e.g. skin) Collagen is a
rod-shaped molecule 3000Å long and just 15Å in
diameter It consists of three strands of
polypeptide chain coiled around one another in a
left-handed polyproline II helical conformation
2
Collagen
Collagen contains large amounts of proline and
has a glycine every third residue The prolines
stabilize the polyproline II helix (f,y)
(-70,140)
3
Collagen
A glycine every third residue is critical for the
three chains to pack against one another Genetic
mutations that result in something other than
glycine cause osteogenesis imperfecta (brittle
bone disease)
