Document Summary
Glycogen can be stored in the liver or muscles in animals. Cellulose is dietary fiber in our diets (not fuel) Colon cells can be damaged by toxic matter if holding" it in. Join because atoms have to bond to have a full valence shell. Remove hydrogen from one molecule, oh from another, h2o. Dehydration synthesis: removal of water and the subsequent bonding of building blocks. Hydrolysis: breaking molecules with water; blast water to break bond, split into h and oh. No bends, kinks, twists: all carbons bonded by single bonds, straight chain. Can be compressed solid animal fats solid at room temperature. Double bonds (at least one in hc chain) Glycerol + two fatty acids + one phosphate. Aspirin blocks enzyme that allows conversion of arachidonic acid to prostaglandin. The biomolecules most commonly serving as fuel for cell are carbohydrates, lipids, and proteins. Prostaglandins, specifically eicosanoid lipids, are lipids involved in inflammation and pain.
