Bioc192: Biochemical Functions Of Vitamins And Minerals

Front 1

Biochemical function of vitamin A

Back 1

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)

Front 2

Biochemical function of vitamin C

Back 2

Antioxidant, also important in the hydroxylation of amino acids for collagen synthesis, also helps with absorbing iron

Front 3

Biochemical function of vitamin D

Back 3

Used to absorb calcium and phosphorus to create bone, helps maintain a healthy nervous and immune system

Front 4

Biochemical function of vitamin E

Back 4

Maintenance of membrane integrity, prevents oxidation of unsaturated fatty acids

Front 5

Biochemical function of vitamin K

Back 5

Promotes normal growth and development, essential for kidney functioning and normal blood coagulation

Front 6

Biochemical function of vitamin B1 - Thiamin

Back 6

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

Front 7

Biochemical function of vitamin B2 - Riboflavin

Back 7

Acts as an electron carrier in redox reactions, also helps in intestinal absorption

Front 8

Biochemical function of vitamin B5 - Pantothenic acid

Back 8

Functions as part of coenzyme A - citric acid and blood cells

Front 9

Biochemical function of vitamin B6 - Pyridoxine

Back 9

Part of the coenzymes pyridoxal phosphate (PLP) and pyradoxamine phosphate (PMP). Used to treat PMS and carpal tunnel

Front 10

Biochemical function of vitamin B7 - Biotin (Vitamin H)

Back 10

Functions with folate in one carbon metalbolism and in amino acid and odd chain fatty acid catabolism

Front 11

Biochemical function of vitamin B12 - Cobalamin

Back 11

Bind enzymes, carboxylation reactions

Front 12

Biochemical function of vitamin B9 - Folate/Folic acid

Back 12

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)

Front 13

Biochemical function of mineral selenium

Back 13

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.

Front 14

Biochemical function of mineral iodine

Back 14

Essential hormone development in the human body

Front 15

Biochemical function of mineral iron

Back 15

Assists many enzymes, carries oxygen around the body

Front 16

Biochemical function of mineral zinc

Back 16

All types of metabolism, in particular: growth
