WebLipids perform many functions within the body: 1) Store Energy – When we take in more energy than we need, the body stores it as adipose tissue (fatty tissue, which we call fat). Carbohydrates and lipids provide most of the energy required by the human body. As discussed in the Carbohydrates unit, glucose is stored in the body as glycogen. WebIn this process, the hydroxyl group of one monosaccharide combines with the hydrogen of another, releasing a molecule of water and forming a covalent bond known as a glycosidic linkage. For instance, the diagram below shows glucose and fructose monomers combining via a dehydration reaction to form sucrose, a disaccharide we know as table sugar. irb and public health
