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. The plasma osmolarity is sensitive to changes in hydration status during dehydration and rehydration.
serum osmolality. 1  a measure of the number of dissolved particles per unit of water in serum. 2  Measurement of the serum osmolality gives information about the hydration status within the cells because of the osmotic equilibrium that is constantly being maintained on either side of the cell membrane (homeostasis).
