0

Riboflavin named Vitamin B2, is a B-complex vitamin which is found in foods and used as a dietary supplement. The sources of food for riboflavin includes milk, green vegetables, eggs, meat, almonds, mushrooms and other dairy products. It plays a key role in energy metabolism. The name riboflavin refers both to a component of its molecular structure and also its yellow color: ribo- with respect to the ribose (a simple sugar) portion of the molecule and flavin from the Latin word for yellow, flavus. Riboflavin is an orange to yellow compound with three ring structure and two nitrogens in each of two of rings. It has chemical formula C17H20N4O6 and has melting point at 290°C. Vitamin B2 could be rapidly broken down by heat and upon the exposure to light; it converts to lumiflavin, being a compound that sabotage Vitamin C. The IUPC name of Riboflavin is 7,8-dimethyl-10- ((2R,3R,4S)- 2,3,4,5-tetrahydroxypentyl) benzo[g]pteridine-2,4 (3H,10H)-dione.

Vitamin B2 is a water soluble vitamin which is involved in number of oxidative enzyme systems in electron transport. It is a central component of two major coenzymes flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) essential to all flavoproteins. These coenzymes has major role in cellular growth, function & development, energy production, metabolism of fats, steroids and fats. For the conversion of amino acid tryptophan to niacin requires FAD. Likewise, FMN is required for the conversion of Vitamin B6 to coenzyme pyridoxal 5’-phosphate. Vitamin B2 is required for various cellular processes. Moreover, riboflavin maintains normal levels of homocysteine which is an amino acid in blood.

Is Riboflavin stable during cooking and storage?

Riboflavin seems to be more stable than Vitamin C and Thiamint with regard to cooking and storage. Foods lose important riboflavin losses when exposed directly to light. It was a bigger concern when milk was packaged in clear glass bottles and delivered to your doorstep before people got out of bed. The milk would then be exposed to the morning sunlight till it was brought in the house. The milk producers no longer packaged their product in glass bottles as this helped milk to retain most of its riboflavin. Cooking foods and sun drying in an open pot results to significant losses of riboflavin losses. In addition like other water-soluble vitamins, it could be washed away during boiling and thawing.

This makes the clear view of riboflavin being heavily involved with aerobic energy metabolism. Typically, status of riboflavin is assessed by taking sample of blood and determining the activity of process which requires riboflavin for efficient operation. Being water soluble, riboflavin is lost from body in urine which makes obvious urine to look bright yellow short time after ingesting the supplements of riboflavin.

What happens if too little or too much Riboflavin is consumed?

Riboflavin deficiency occurs by itself. A person consuming diet low in riboflavin shows signs of deficiency after couple of months such as inflammation of mouth and tongue.

Digestive system when healthy allows proper absorption and use of nutrients from diet we consume. This makes the view clear that insufficient riboflavin causes fewer nutrients to be used for energy in the body.

  1. Cure for anemia

Anemia is caused due to the low production of red cells and being unable to deliver oxygen to blood and also blood loss. Vitamin B2 is engaged in these functions so helps to treat anemia. Along with it is also used for treating sickle cell anemia. Both of these conditions are caused due to the deficiency of riboflavin. Vitamin B2 demanded for steroid hormone synthesis and production of red blood cells. It assist in delivering oxygen to the cells and also to utilize iron. Those with riboflavin deficiency should add Vitamin B2 to the diet otherwise they would be prone to onset of anemia and sickle cell anemia. Vitamin B2 effectively lowers high amount of homocysteine in blood.
