___________ can be used by cells to store energy, form biological membranes, and serve as chemical messengers.
Outcome: Model structure and function of lipids and proteins. •Warm-up: 1. What are the building blocks of carbohydrates? 2. Name the importance of carbohydrates. 3. What are the three main types of carbohydrates? Differentiate them. 4. What is the function of cellulose? – Lipids are a large and varied group of biological molecules. Lipids are made mostly from carbon and hydrogen atoms and are generally not soluble in water. – The common categories of lipids are fats, oils, and waxes. – Lipids can be used to store energy. Some lipids are important parts of biological membranes and waterproof coverings. – Steroids synthesized by the body are lipids as well. Many steroids, such as hormones, serve as chemical messengers. -large and varied group of biological molecules that are generally not soluble in water-made mostly from carbon/hydrogen atoms-fats, oils, and waxes-can be used to store energy-some lipids are important parts of biological membranes and waterproof coverings-may steroids, such as hormones, serve as chemical messengers View Full Document. 1  2. Lipids: used To sTore energy, are The major componenTs of cell membranes, and serve as chemical messengers. 3. ProTeins: help cells keep Their shape, make up muscle tssues, speed up chemical reactons in cells, TargeT foreign partcles (such as bacTeria) for desTructon, and some carry messages or maTerials. 4. – Many animals store excess sugar in a polysaccharide called glycogen. – When the level of glucose in your blood runs low, glycogen is broken down into glucose, which is then released into the blood. – The glycogen stored in your muscles supplies the energy for muscle contraction. – Lipids are a large and varied group of biological. molecules. Lipids are made mostly from carbon and. hydrogen atoms and are generally not soluble in water. – The common categories of lipids are fats, oils, and. waxes. – Lipids can be used to store energy. Some lipids are. important parts of biological membranes and waterproof. coverings. – Steroids synthesized by the body are lipids as well. --used in determining ages of rocks, killing bacteria in food, treatment of cancer, and can follow the movement of substances in organisms. compounds (chemical) -a substance formed by the chemical combination of two or more elements in definite proportions (comparative relation) -compounds are special. --the physical and chemical properties of a compound are usually very different from those of the elements from which it is formed. --the properties are shown by a chemical formula. ----ex.) Water is H2O, table salt is NaCl, etc. Big idea: basic chemical principles that affect living things--the process of science helps Biologists investigate how nature works at all levels; from the molecules in cells to the biosphere. controlling the rate of reactions and regulating cell processes, forming cellular structures, transporting substances into or out of cells, and helping to fight disease. -can be used to store energy -some lipids are important parts of biological membranes and waterproof coverings -may steroids, such as hormones, serve as chemical messengers -lipids are formed when a glycerol molecule combines with compounds called fatty acids
