SIMPLE PROTEINS

The proteins are made of amino acids only.

Additional chemicals are absent.

These are of two types -   (i) Fibrous        (ii) Globular

(i)      Fibrous Protein -

  • 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.
  • Trypomyosin, Myosin & Actin - Present in muscle
  • Tubulin - Present in spindle fibres.

(ii)     Globular Protein -

  • 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)

  • Histone - It is basic protein, present in eukaryotes, arginine & histidine amino acids are more in quantitiy in histone protein, it combine with DNA to form chromosomes.
  • Protamines - Present in sperms.
  • Prolamines - Have maximum number of proteini amino acids - Hardein - Present in Barley. Glidine - Present in wheat. Glutelins - Present in Cerels. Zein - Present in maize. Oryzenin - Present in rice.
