WebMost water soluble vitamins are available for intestinal absorption from two sources: 1) the diet, and 2) synthesis by microbes in the large intestine or, in the case of ruminants, the rumen. These dual-origin vitamins include biotin, … However, micelle formation may also inhibit chemical reactions, such as when reacting molecules form micelles that shield a molecular component vulnerable to oxidation. Micelle formation is essential for the absorption of fat-soluble vitamins and complicated lipids within the human body.
