Biochemical function of vitamin A |
Important for vision. Retinal comes from vitamin A, light converts 11-cis --> trans form which causes opsin to change shape (which sends a nerve signal) |
|
Biochemical function of vitamin C |
Antioxidant, also important in the hydroxylation of amino acids for collagen synthesis, also helps with absorbing iron |
|
Biochemical function of vitamin D |
Used to absorb calcium and phosphorus to create bone, helps maintain a healthy nervous and immune system |
|
Biochemical function of vitamin E |
Maintenance of membrane integrity, prevents oxidation of unsaturated fatty acids |
|
Biochemical function of vitamin K |
Promotes normal growth and development, essential for kidney functioning and normal blood coagulation |
|
Biochemical function of vitamin B1 - Thiamin |
Part of the coenzyme thiamin pyrophosphate (TPP) which assists in energy metabolism in all cells. Also situated on the membranes of nerve cells and has a role in nerve function. Has a rapid turn-over |
|
Biochemical function of vitamin B2 - Riboflavin |
Acts as an electron carrier in redox reactions, also helps in intestinal absorption |
|
Biochemical function of vitamin B5 - Pantothenic acid |
Functions as part of coenzyme A - citric acid and blood cells |
|
Biochemical function of vitamin B6 - Pyridoxine |
Part of the coenzymes pyridoxal phosphate (PLP) and pyradoxamine phosphate (PMP). Used to treat PMS and carpal tunnel |
|
Biochemical function of vitamin B7 - Biotin (Vitamin H) |
Functions with folate in one carbon metalbolism and in amino acid and odd chain fatty acid catabolism |
|
Biochemical function of vitamin B12 - Cobalamin |
Bind enzymes, carboxylation reactions |
|
Biochemical function of vitamin B9 - Folate/Folic acid |
Functions in one carbon metabolism, synthesis of purines and pyridamines - prevention of neural tube defects, failure of tube closing properly can result in spino bifida or anencephaly (if further up). (around 9 in 10,000 births) |
|
Biochemical function of mineral selenium |
Cofactor for enzymes - glutathione peroxidase (GPx) - helps arrest lipid peroxidation, control of free radicals, convert fatty acids peroxides into fatty alcohols. Iodothyronine deiodinase - thyroid function (T4-->T3). Thioredoxin reductase. 25 selonoproteins in mammals. |
|

Essential hormone development in the human body |
|
Biochemical function of mineral iron |
Assists many enzymes, carries oxygen around the body |
|
Biochemical function of mineral zinc |
All types of metabolism, in particular: growth |
