Riboflavin Absorption in Children With Biliary Obstruction

Formation and Mode of Action of Flavoproteins

“…It has also been observed (17) that riboflavin absorption is increased by exposure to ,),-radiation, which decreases the rate of gastric emptying. The presence of bile salts increases uptake (106,155); furthermore, impaired riboflavin absorption is observed in children with biliary obstruction (107). Although bowel disorders might generally de crease uptake, children with gastroenteritis have normal levels of riboflavin (4).…”

Flavins: Riboflavin, FMN and FAD (Vitamin B 2 )

“…jejunum and ileum) in the guinea pig (Hegazy & Schwenk, 1983) and the rabbit (Said et al, 1993a). A role of bile salts is also indicated by impaired absorption of ribofl avin in cases of biliary obstruction in children (Jusko et al, 1971). A role of bile salts is also indicated by impaired absorption of ribofl avin in cases of biliary obstruction in children (Jusko et al, 1971).…”

Riboflavin and other flavins (vitamin B2)

“…Absorption is enhanced by the presence of bile salts in the intestinal lumen (Mayersohn, Feldman and Gibaldi, 1969). A role of bile salts is also indicated by impaired absorption in cases of biliary obstruction in children (Jusko et al, 1971). Bile salts may increase the absorption of riboflavin in the following possible ways.…”
