Lipids are made of a triglyceride that is made from the alcohol glycerol, plus fatty acids. Include how its structure dictates its function. Their structure can vary significantly, influencing their function in biological systems. These tissues serve as reservoirs for energy and also play a role in insulating and cushioning the body. , Compare and contrast the four biomolecule families: carbohydrates, proteins, nucleic acids, and lipids. Lipids are nonpolar: As the hydrocarbon component (the alkyl group) of an organic compound increases in size, the relative contribution of a polar functional group to the physical properties of the molecule decreases. To understand the general structure and properties of lipids and phospholipids “Lipids are organic compounds that contain hydrogen, carbon, and oxygen atoms, which form the framework for the structure and function of living cells. How does the structure of an amino acid relate to it's function in cellular processes? Use the role of amino acids Carbohydrate - Energy, Structure, Nutrition: The importance of carbohydrates to living things can hardly be overemphasized. 2. Lipids accumulate in adipose cells (fat cells) in the body. Structure of Lipids. Lipids are made of 1 glycerol and 3 fatty acids (NO true monomer) Describe the structure of biologically-important molecules (carbohydrates, lipids, proteins, nucleic acids, water) and how their structure leads to their function. Cells make a variety of macromolecules needed for life processes from a relatively small set of monomers. Fats are also Learn about the structure of biological molecules for your IGCSE exam. Unlike carbohydrates and proteins, lipids are hydrophobic, meaning they do not dissolve in water. Carbohydrates, such as starch and glycogen, are used for energy storage and structure in plants and animals. 9 3 Monomer Polymer Cellular context Nucleotide (ex Lipids provide an energy storage structure and enable the transport of key compounds required for survival. Functions of carbohydrates. Carbohydrates are vital for energy in humans and Fats are a sub-group of compounds known as lipids that are found in the body and have the general property of being hydrophobic (meaning they are insoluble in water). c) Lipids mix poorly with water. Figure 1. Carbohydrates and lipids are essential elements in all living things. Lipids, however, are hydrophobic (“water-fearing”). 10 terms. Carbohydrates are furthe Structure: Carbohydrates are composed of carbon, hydrogen, and oxygen atoms, while lipids are primarily made up of fatty acids and glycerol.
