It follows the curvature of the sacrum and is firmly attached to it by connective tissue. By forming an emulsion, bile salts increase the available surface area of the lipids many fold.

These molecules can pass through the plasma membrane of the cell and enter the epithelial cells of the intestinal lining. The bile salts surround long-chain fatty acids and monoglycerides forming tiny spheres Anus and rectums functiond and enzymes micelles. The micelles move into the brush border of the small intestine absorptive cells where the long-chain fatty Adelgazar 15 kilos and monoglycerides diffuse out of the micelles into the absorptive cells leaving the micelles behind in the chyme.

The long-chain fatty acids and monoglycerides recombine in the absorptive cells to form triglycerides, which aggregate into globules and become coated with proteins.

These large spheres are called chylomicrons. Chylomicrons contain triglycerides, cholesterol, and other lipids and Anus and rectums functiond and enzymes proteins on their surface.
