How do lipids work with other molecules
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. WebLipids Lipids are esters of fatty acids and glycerol. In a lipid, there may be 1, 2 or 3 fatty acids combined with glycerol. Fatty acids 1, 2 and 3 may be the same, or different Lipid...
