Triglyceride is the most common one we eat in our everyday food‚ they are fats and oils. This kind of lipid has a glycerol head with three fatty acid chains which is where the energy

metabolism: The sum of all biological chemical reactions inside a cell or organism Differences in catabolism and anabolism: Catabolism is an enzyme-regulated chemical reaction that releases energy. Complex organic compounds such as glucose‚ amino acids‚ glycerol and fatty acids are broken down into simpler ones. The energy of catabolic reactions is used to drive the anabolic reactions. Anabolism is also enzyme regulated but requires energy for taking the simpler broken down components from the catabolism

Structures and functions of the Digestion System This essay aims to explain the structure and functions of the digestion system‚ starting from consuming a cooked dinner to chemical and physical changes within the body‚ to prepare or help absorption of vital nutrients and help disposal of waste. The structure of the digestive system starts with the gastrointestinal tract‚ it is a tube that runs from the mouth to the anus and because of this some scientist says it is an external organ; there

able to assemble polymers from monomers and to disassemble polymers into monomers? Biological polymers (proteins‚ polysaccharides‚ nucleic acids) and lipids are assembled by dehydration synthesis; they are disassembled into their monomers (or into glycerol + fatty acids in the case of lipids) by hydrolysis reactions. 7. Explain why sugars are an essential part of our diet. Your brain can not function without glucose‚ it is also used for ATP construction within your cells‚ hence the use of insulin
