Digestion and Absorption
The gastrointestinal absorption of riboflavin and flavin mononucleo- tide (FMN) was determined under control conditions and after oral administration of 600 mg sodium deoxycholate. ... Urinary excretion data also suggest an unusually prolonged absorption of riboflavin in the presence of the bile salt.
Bile contains bile acids, which are critical for digestion and absorption of fats (cholesterol)and fat-soluble vitamins (e.g.vit A)in the small intestine. Many waste products, including bilirubin, are eliminated from the body by secretion into bile and elimination in feces
It is suggested that in addition to their emulsifying action bile salts may stimulate the esterification of absorbed oleic acid by the intestinal mucosa. ... of fatty acids by the small intestinal mucosa, and the subsequent route of transport after absorption.
