Document Summary

Vitamins are organic molecules our body needs in order to function: organic molecules contain carbon. Minerals are inorganic molecules (periodic table) that our body needs in order to function.

Make and maintain tissues like bones and blood. Organic molecules that we need to eat for our bodies to function well. We talk about vitamins being either water-soluble or fat soluble. Transported into intestinal cells using facilitated diffusion or active transport. Transported in the body bound to blood proteins. Are best absorbed when eaten with fat, absorbed in micelles. Are absorbed into intestinal cells via chylomicrons. Carried through lymphatic system, passes through intestinal wall. Transported in the body as lipoproteins or bound to transport proteins. Often stored in the body (in body fat), not easily excreted! Fat-soluble vitamins require bile and dietary fat for absorption.
