1. Be able to draw and recognize the hydroxyl, carbonyl, carboxyl, amino, sulfhydryl, and phosphate groups that are found on organic molecules. Be able to recognize them on molecules like those examples in class. Which of these are normally ionized in biological solutions (cell cytoplasm, etc) What are the functional groups that are found in alcohols, carboxylic acids, thiols, and amines? Hydroxyl -OH Carbonyl >CO Carboxyl -COOH Amino -NH 2 Sulfhydryl -SH Phosphate -OPO 3 2- Hydroxyl, Carbonyl, Carboxyl, and Amino are ionized in biological solutions. Functional groups found in alcohols – Hyrdoxyl Carboxylic acids- Carboxyls Thiols – Sulfhydryls Amines – Amino 2. Define the term macromolecule. What is a polymer? How are important biological macromolecules lengthened and shortened by condensation and hydrolysis reactions? Macromolecules are large molecules such as carbs, lipids, proteins, and nucleic acids. In condensation, macromolecules are lengthened by the addition of another monomer, this takes place when a hydroxyl links with a hydrogen from a polymer and breaks a water molecule off. It is the exact opposite in hydrolysis. 3.
