  • Keratin - present in hair
  • Elastin - Present in elastic fibre, also called yellow fibres (form ligament) because these fibres are yellow in colour.
  • Collagen - Present in tendon also called white fibre, it is present in maximum amount in human body. Also present in dentine of teeth in the form of Shape's fibre.

  • Albumin - Present in maximum amount in blood, it maintains blood colloidal osmotic pressure.
  • Globulin - It is of 3 types -
  • a - globulin - e.g. ceruloplasmin (Copper transporting protein) b - globulin - e.g. transferrin (Iron transporting proetin) g-globulin - e.g. antibodies (Immunoglobulin)
