Angela Santaguida, Andrew Stolman Chapter 5 Top Ten Concepts 1. Macromolecules are polymers 2. Polymers are covalently bonded monomers 3. Carbohydrates are used for energy, with the simplest being monosaccharides which are the building blocks of more complex sugars. 4. Hydrolysis breaks down polymers by having chemical compounds interact with water. 5. DNA carries all of the body’s genetic information. It is a nucleic acid that codes for proteins in the body. 6. Molecules have three main structural levels; Primary, Secondary, and Tertiary. Primary structure specifies its atomic composition, and the chemical bonds that keep them together. Secondary structure is the general three- dimensional form of polymers and nucleic acids. Tertiary structure is similar to Secondary, but it is

Lipids function as storage for energy in cells, assistants for cell signaling, and structural components of cell membranes. 8. The structural units of DNA and RNA are nucleotides, which are composed of a phosphate group, a pentose sugar, and a nitrogenous base. Nucleotides play important roles in both cell signaling and metabolism regulation. 9. RNA, or ribonucleic acid, is a nucleic acid that is transcribed from DNA, and is single stranded. RNA translates nucleic acids into proteins, and messenger RNA carries information from DNA out to the ribosomes so they can create proteins. 10. The main components of all biological membranes are phospholipids, glycolipids, cholesterol, and proteins....
