Document Summary

Examples: milk, pastries, cookies, cake, cheese, hot dogs, biscuits, crackers, etc. Low fat = <3 grams fat per serving. Gastric lipase works only in an acidic. Gastric lipase acts on triglycerides containing short and medium chain fatty acid(less common) Longer fatty acid chain are not digested in the stomach(more common) Creates an interface with the water environment. Promotes the formation of micelles: increases the surface area for the lipase to act. Bile is produced in the liver: stored in the gallbladder, released by the gallbladder into the small intestine. Diffuse into the absorptive cells of the small intestine. Short and medium chain fatty acids are water soluble: enters the portal system, on to the liver. Long chain fatty acids reforms into triglycerides: eventually enters the lymphatic system. ***know how fat is broken down, where, and what is responsible for what. Transportation of digested lipids:from small intestine to cells. Packages as: vldl= very low density lipoprotein: vldl= triglyceride rich.
