Question

7. Microelements (Fe, Zn, Mn, Cu, Co) as components of nutrition. Biochemical role.

(please explain with more explanation its my final exam question...thank you ! :))

Answer 1

Fe (iron) - It is the most essential tace element which is required for the proper growth and metabolism of the cell. It is also reequired to make Heamoglobin(Hb),Ferritin, tranferrin, myoglobin, heamosiderin molecules and fuction of some iron dependent enzymes eg. cytochrome oxidase, xanthine oxidase and peroxidase.

Zn (Zink)- It is 2nd most abundant trace element it is a cofactor of several enzyme which play significant role in metabolism eg. Dna ploymerase, alkaline phosphatase and corboxypeptidase.

Mn (maganese). Mn is involved in protein and fat metabolism and required for healthy nervous system, bone growth, digestive system and immune function. it is also nessesory for the functon of very important antioxidant enzyme Superoxide dismutase (SOD).

Cu (Copper). iT is third most important trace element transported through mettaloenzymes such as ascorbic acid. This trace element is needed for the erythropoesis, nerve conduction and immune function. It works as a catlyst for tyrosinase and asccorbic acid.

Co (Cobalt). Central in corrin ring of vitamin B12 defficiency of this minerals results in pernicious anemia
