(For more information about amino groups, see Chapter 15 'Organic Acids and Bases and Some of Their Derivatives', Section 15.1 'Functional Groups of the Carboxylic Acids and Their Derivatives'.) The amino acids in proteins are α-amino acids, which means the amino group is attached to the α-carbon of the carboxylic acid. The proteins in all living species, from bacteria to humans, are constructed from the same set of 20 amino acids A molecule that contains an amino group and a carboxyl group., so called because each contains an amino group attached to a carboxylic acid. Recognize amino acids and classify them based on the characteristics of their side chains.We end the chapter with a discussion of enzymes-the proteins that act as catalysts in the body. We begin our study of proteins by looking at the properties and reactions of amino acids, which is followed by a discussion of how amino acids link covalently to form peptides and proteins. Immunoglobulins recognize and breakdown foreign molecules. Protect cells or the organism from foreign substances Ovalbumin stores amino acids in the egg white that will be used by the developing bird. Insulin regulates the activity of specific enzymes in the body. Regulate the functioning of other proteins Hemoglobin transports oxygen from the lungs throughout the body. Transport substances from one place to another Myosin is one protein needed for the contraction of muscles. Keratin is the primary protein of hair and wool. Α-Amylase catalyzes the hydrolysis of starch and glycogen. Table 18.1 Classification of Proteins by Biological Function Classification
