Bioavailability of Dietary Carotenoids: Intestinal Absorption and Metabolism
Various carotenoids with diverse structures are present in foods and have been reported to have beneficial effects on human health. Owing to their hydrophobicity, however, poor solubilization in the aqueous milieu of the digestive tract restricts their intestinal absorption. Fats and oils were found to increase the solubilization of carotenoids into mixed-micelles, which would therefore enhance...
متن کاملAbsorption, transport, and metabolism of carotenoids in humans
Vitamin A, which is an essential nutrient for humans, may be provided in the diet either as preformed vitamin A or as provitamin A carotenoids. The bioavailability of carotenoids in foods varies greatly, depending on many factors. Carotenoids are emulsified and then are solubilized in micellar form within the intestine with an absolute requirement for conjugated bile salts. Dietary carotenoids ...
متن کاملPhysiological Functions and Metabolism of COX
Prostaglandin metabolism plays a pivotal role in inflammatory processes and has also been demonstrated to have a role in carcinogenesis, tumor differentiation and tumor growth in breast cancer. Cyclooxygenase-2 (COX-2) is the key involved enzyme, as it triggers prostaglandin synthesis. We reviewed the current literature regarding the impact of prostaglandin metabolism on breast cancer and illus...
متن کاملPhosphatidylinositol-3,5-bisphosphate: metabolism and physiological functions.
Phosphatidylinositol (PtdIns) is a membrane phospholipid composed of diacylglycerol and a D-myo-inositol head group. In mammals, the hydroxyl groups at the D3, D4 and D5 positions of the inositol ring can be phosphorylated to yield seven phosphoinositide derivatives. PtdIns-3,5-bisphosphate [PtdIns(3,5)P2] is the most recently discovered species of phosphoinositide that is generated by the phos...
متن کاملIntestinal absorption of dietary carotenoids.
The assessment of carotenoid bioavailability has long been hampered by the limited knowledge of their absorption mechanisms. However, recent reports have elucidated important aspects of carotenoid digestion and absorption. Disruption of food matrix and increasing amounts of fat seem to enhance the absorption of carotenes to a larger extent than that of xanthophylls. Comparing different caroteno...
