Iron binding protein is: September 2010: (A) Ferritin, (B) Ferropoin 1, (C) Transferrin, (D) Hephaestin
Answer is C. Ans. C: TransferrinIron-binding proteins are carrier proteins and metalloproteins which play many impoant roles in metabolism. They bind Iron and can therefore inhibit microbial growth.Two iron-binding proteins are lactoferrin and transferrin.Some of the iron after absorption is stored in ferritin, and the remainder is transpoed out of the enterocytes by a transpoer named ferropoin 1. Hephaestin is associated with ferropoin 1.
