In this blog, let's learn more about the topic of biochemistry, which is handled by our esteemed faculty member, Dr. V.S. Kumar. Today, let's focus on the topic ‘Collagen’.

              Collagen


1) Most abundant protein in the body
2) Major structural protein in ECM

  • Tropocollagen is the monomer unit
  • Consist of 3 α chains – left hand structures but on combination right handed triple helix

  • Components:
    Glycine residue, -OH proline & OH-lysine
    Gly-x-y repeat
    Synthesis:
    Endoplasmic recticulum of fibroblast

    Stage 1:

    Formation of α-chains → Combine → Pre-pro-collagen

    Stage 2:

    Hydroxylation of Proline & Lusine
    Glycosylation to OH- Lysine
    Intracellular event- convert → Pre-pro-collagen → Procollagen
    Extracellular event
    Stage: Tropocollagen is formed

    Types:

    Type 1: Skin & bONE
    Type 2: CarTWOlage
    Type 3: ArTHREE
    Type 4: Basemnet membrane floor

    Disorders of Collagen:

    Type 1:

  • Osteogenesis Imperfecta aka Brittle bone d’s
  • Osteoporosis
  • Ehler danlos syndrome
  • Type 2:

    Chondrodysplasia
    Osteoarthritis

    Type 3:

    EDS

    Type 4:

    Good Pasteurs & Alports Syndrome
    Scurvy → ATP-7x mutation
    Menkes kinky hairs disease
    Wilson’s (ATP-7B mutation)
