Vitamin B2Vitamin B2 also known as Riboflavin or E101 (additive) is a micronutrient required by humans and other animals for maintaining health. It is also responsible for causing the florescent yellow color in urine when a person has taken high dose B-complex preparations. Vitamin B2 is easily absorbed by the body and is the central component of cofactors FAD and FMN, required by all flavoproteins. The name riboflavin is derived from the sugar which forms part of its chemical structure, “ribose.” Ribose is a transposition of arabinose and “flavin.” Riboflavin is known as the vitamin which gives the orange color to solid B-vitamin preparations and the yellow color to vitamin supplement solutions.
