Vitamin B6 and Vitamin B2 crystals

Vitamin B6 and Vitamin B2 crystals



Image Number: 870806-39

Caption:

Vitamin B6 (pyridoxine) and Vitamin B2 (riboflavin) crystals. Vitamin B6 is a water-soluble vitamin that exists in three major chemical forms: pyridoxine, pyridoxal, and pyridoxamine. In the liver pyridoxine and pyridoxamine are converted to pyridoxal 5'-phosphate (PLP) which is a cofactor in many reactions of amino acid metabolism. PLP also is necessary for the enzymatic reaction governing the release of glucose from glycogen. Vitamin B6 is needed for more than 100 enzymes involved in protein metabolism. It is also essential for red blood cell metabolism. The nervous and immune systems need vitamin B6 to function efficiently, and it is also needed for the conversion of tryptophan to niacin (Vitamin B3). Vitamin B6 deficiency can result in pyroluria. An overdose of pyridoxine can cause a temporary deadening of certain nerves such as the proprioceptory nerves, causing a feeling of dissembodiment common with the loss of proprioception. Vitamin B2 (riboflavin) is a soluble and heat stable factor in B complex vitamins. Like the other B vitamins, it supports energy production by aiding in the metabolism of fats, carbohydrates, and proteins. Vitamin B2 is also required for red blood cell formation and respiration, antibody production, and for regulating human growth and reproduction. It is essential for healthy skin, nails, hair growth and general good health, including regulating thyroid activity. Riboflavin also helps in the prevention or treatment of many types of eye disorders, including some cases of cataracts. Milk, cheese, leafy green vegetables, liver, yeast, almonds and mature soybeans are good sources of Vitamin B2.
