What are vitamins functions?

Answer 1

B complex vitamins are water-soluble and mainly participate in the cell metabolism. There are 8 B vitamins which have slightly different, specific functions in the cell metabolism.

Depending upon the vitamin B we are talking about. That is,

Vitamin B1 or thiamine: essential nutrient required for carbohydrate metabolism; also involved in nerve function. Thiamine is converted in vivo to thiamine diphosphate, a coenzyme in the decarboxylation of alpha-keto acids. Deficiency of thiamine causes Beriberi.

Vitamin B2 or riboflavin: Is a minor but crucial component in metabolic processes. One of the is linked to the glutathione reductase activity (this enzyme catalyzes the NADPH-dependent reduction of glutathione disulfide, or GSSG, to glutathione, or GSH. GSH acts as a coenzyme in several enzymatically catalyzed reductions and plays an important role in the transport of amino acids into certain cells.). Glutathione reductase has an electron-transfer prostethic group, the flavin adenine dinucleotide or FAD. FAD as all flavins, contains the isoalloxazine ring, that allows it to perform processes of sequential electron transference. Humans are unable to synthezise the isoalloxazine component of flavins, so they have to consume food with flavin content, mainly in the form of riboflavin.

Vitamin B6 or pyridoxin: Crucial in aminoacid deamination, the first reaction of amino acid breakdown, to remove excess nitrogen through urea. The coenzyme pyridoxal-5'-phosphate (or PLP), a derivative of vitamin B6, is required by aminotransferases during degradation of amino acids.

Vitamine B12 or cyanocobalamine: It is converted by the body into its bioactive forms, such as: methylcobalamine and cobamamide, which serves as important enzyme cofactors. Severe deficiency may result in megaloblastic anemia and/or neurological impairment.

Answer 2

Every day, your body produces skin, muscle, and bone. It churns out rich red blood that carries nutrients and oxygen to remote outposts, and it sends nerve signals skipping along thousands of miles of brain and body pathways. It also formulates chemical messengers that shuttle from one organ to another, issuing the instructions that help sustain your life.

But to do all this, your body requires some raw materials. These include at least 30 vitamins, minerals, and dietary components that your body needs but cannot manufacture on its own in sufficient amounts.
