Final answer:
Riboflavin, also known as vitamin B2, can be obtained from foods or synthesized in the body in small quantities. It is important for various physiological functions.
Step-by-step explanation:
Riboflavin, also known as vitamin B2, can be obtained from foods as well as synthesized in the body in small quantities. It is found in animal sources like milk, liver, kidney, heart, and egg yolk, as well as in sprouts. The daily recommended amount of riboflavin is 1.5-2.0 mg/day on average.
The body synthesizes riboflavin through a process of converting ribityl alcohol to riboflavin phosphate, also known as flavin mononucleotide (FMN), and then linking it to an adenosine nucleotide to form flavin adenine dinucleotide (FAD). These active coenzyme forms of riboflavin play important roles in various physiological functions, including carbohydrate metabolism and the regulatory functions of certain hormones.
While it is possible to obtain riboflavin from foods, the body can also synthesize it in small quantities, making it an essential nutrient that is required for bodily function.
