Document Summary

The fats, carbohydrates, and proteins are used for energy or to build structures. Metabolism is defined as the chemical changes that occur within a cell to either manufacture store energy, or build new cell structures. Energy molecule used by the body: adenosine triphosphate/atp. Triglycerides, which make up most of the fat found in the body, consist of three fatty acid chains attached to one molecule of glycerol. Proteins consist of long chains of amino acids linked together, and carbohydrates are long chains of monosaccharides (like glucose) joined together. Large molecules are broken down in digestive tract and absorbed: once in the body some may partially reform, while others stay as building blocks. The carbohydrates glucose is stored inside muscle and liver cells in the form of glycogen. Fats are stored as triglycerides inside fatty tissue called adipose tissue. The amino acids become structural or functional proteins inside the muscle cells.
