Biological macromolecules all contain carbon in ring or chain form, which means they are classified as organic molecules. They usually also contain hydrogen and oxygen, as well as nitrogen and additional minor elements. Four Classes of Biological Macromolecules. There are four major classes of biological macromolecules: carbohydrates; lipids; proteins

Elements & Macromolecules in Organisms (2.3) Most common elements in living things are carbon, hydrogen, nitrogen, and oxygen. These four elements constitute about 95% of your body weight. All compounds can be classified in two broad categories --- organic and inorganic compounds. Organic compounds are made primarily of carbon. Macromolecules Worksheet #2 Name Per. Part A. Classify each as a carbohydrate, protein, lipid or nucleic acid. 1. starch 10. polysaccharide 2. cholesterol 11. phospholipid 3. steroid 12. glycerol 4. glycogen 13. monosaccharide 5. nucleotide 14. cellulose 6.

In living organisms, carbon and hydrogen make easy partners. The element carbon has two orbiting layers, called shells, surrounding its nucleus. The outer shell contains four electrons. These four electrons can form separate covalent bonds with other elements, which means that they bond together by sharing electrons. Practicing Biology : For Biology - Cynthia Giffen, Jane B.

Macromolecules are grouped based on their chemical composition, and functions. Living things use carbohydrates as their main source of energy. Plants, some animals, and other organisms also use carbohydrates for structural purposes.
