The effect of various vitamins

Vitamin A combined with opsin to
generate a rhodopsin, and rhodopsin is a sensitive material that retinal rod
cells are sensitive to low light. When lack of vitamin A, to weak light
sensitivity is reduced and cause blindness.

Vitamin C has reversible oxidation and
reduction, widely involved in many biochemical reactions. The primary function has
been the elucidation is involved in the synthesis of collagen. In addition,
there are several aspects as follows: in intracellular electron transfer
reaction plays an important role; participated in oxidation reaction of some
amino acids; promote intestinal iron absorption and in vivo transporter; reduce
transporter metal ion toxicity effect in vivo; can stimulate leukocytes
phagocytic cells and the function of the reticuloendothelial system; promote
antibody formation; it is natural inhibitors of carcinogenic nitrosamine;
involved in adrenal steroid synthesis.

Vitamin E has the following several
aspects:`the role of
biological antioxidant effect, by neutralizing peroxidation chain generates
free radicals and prevent the generation of free radicals caused oxidative
chain interruption, thus preventing the cell membrane lipid peroxidation and
caused a series of damage;a± – tocopherol can also affect the membrane phospholipid structure
and the influence of biofilm formation; bpromoting the eighteen carbon two acid into twenty carbon four acid thus
synthesis prostaglandin;cvitamin E and selenium deficiency can lower the body ‘s immunity and
resistance to disease; dvitamin E in biological redox systems is cytochrome reductase
cofactors; einvolved
cellular DNA synthesis regulation;freduces copper, mercury, arsenic, silver, other metals and toxic
element toxicity; gthrough containing selenium oxidized glutathione peroxidase turn into
reduced glutathione peroxidase and reduce other peroxide generated to save
selenium, reduce the impact of selenium deficiency; hvitamin E also relates to normal
phosphorylation reactions, such as the synthesis of vitamin C, pantothenic acid
synthesis as well as the sulfur-containing amino acids and vitamin B12

Vitamin H is also called the biotin, many
foods were containing biotin, such as liver, yeast, egg yolk, whole grains,
legumes, nuts, dairy products, it can not be directly absorbed by human body,
through enzyme separation, can be absorbed by the body, can help to conversion
of lactate into glucose, and assist cell DNA synthesis, researches by cosmetic
raw material suppliers
show that biotin can maintain the hair and skin
health, prevent hair loss, skin inflammation and eczema phenomenon, can prevent
anemia, make you have a beautiful complexion.

In vivo, biotin with coenzyme form widely
involved in carbohydrate, lipid and protein metabolism. For example, pyruvate carboxylation,
amino acid deamination, purine and the synthesis of essential fatty acid. Acoording
to biotin
, biotin deficiency is generally performed for poor growth,
dermatitis and hair or feathers fall.

Vitamin B12 in vivo is mainly in deoxyadenosyl cobalamin and mecobalamin
two coenzyme form to participate in a variety of metabolic activity, such as
allopurinol and porphyrin and synthesis, methyl transferHealth Fitness Articles, protein synthesis by
amino acid and carbohydrate and fat metabolism. And two important functions witch
is closely related to the deficiency is to promote the red cells in the
formation and maintenance of the intact nervous system. Vitamin B12 deficiency
will cause ruminant animal rumen fermentation products propionic acid metabolic
disorders. This is the basic metabolic damage produced by ruminant animal
vitamin B12 deficiency.
