The gall bladder produces bile which emulsifies the lipids, which allows them to stay mixed with the water in the digestive tract. The emulsified lipids then move on through the digestive tract into the small intestine. The pancreas produces the enzyme lipase and releases it into the small intestine where it digests triglycerides. The emulsified lipid- bile mixture forms micelles, which are droplets of digested lipids surrounded by bile. Micelles assist the absorption of lipids. Water-soluble fats are absorbed directly into the bloodstream. The cells of the intestinal mucosa rebuild triglycerides from fatty acids. These reassembled triglycerides are surrounded by phospholipids and proteins to form

Any remaining unabsorbed lipids are metabolized by the bacteria that live in the large intestine. Lipids are stored in the body in adipose tissue (the layer of fat that lies under the skin and around the internal organs). The lipids stored in adipose tissue are available for energy when energy is needed. Besides being stored in adipose tissue, lipids are an important component of cells, especially cells in the nervous system and brain. They also provide the lubricating oils that soften our skin....
