Briefly discuss the absorption process and sites of biotin, folate. cobalamin, and ascorbic acid
In essence, human beings cannot synthesize biotin, and therefore the vitamin is required in water soluble form to perform the normal cellular function. The absorption process of biotin takes place in the small and large intestines (Said, 2011). The process involves the Na+ carrier that transports the vitamin in human beings. The sodium-dependent transports, also written as hSMVT is expressed in the apical membrane of the enterocytes. Folates exist as polyglutamate in the diet, which enables them to be converted to mono glutamates through an enzymatic process. The absorption process of the vitamin takes place in the intestines with ...
