Most dietary riboflavin is consumed as a complex of food protein with FMN and FAD (Merrill et al., 1981; Nichoalds, 1981). In the stomach, gastric acidification releases most of the coenzyme forms of riboflavin (FAD and FMN) from the protein.
Plasma osmolarity: The osmolarity of blood plasma, which is a measure of the hydration status. The plasma osmolarity is sensitive to changes in hydration status during dehydration and rehydration.The normal plasma osmolarity is in the range of 280-300 mOs/kg.lasma osmolarity: The osmolarity of blood plasma, which is a measure of the hydration status.

Avascular necrosis is a disease that results from the temporary or permanent loss of blood supply to the bone. It is also called osteonecrosis, aseptic necrosis, or ischemic bone necrosis. When blood supply is cut off, the bone tissue dies and the bone collapses. If avascular necrosis occurs near a joint, collapse of the joint surface may occur. Avascular necrosis may occur in any bone, but most commonly occurs in the ends of a long bone. It may affect one bone, several bones at one time, or different bones at different times.
