Q. 16.2 - An Introduction to General, Organic, and Biological Chemistry

Question

Classify each of the following proteins according to their function:

a. insulin, a protein needed for glucose utilization

b. antibodies that disable foreign proteins

c. casein, milk protein

d. lipases that catalyze the hydrolysis of lipids.

Step-by-Step Solution

Answer

(part a). Insulin, a protein needed for glucose utilization—Hormone

(part b). Antibodies that disable foreign proteins-Protection

(part c). Casein, milk protein-Storage

(part d). Lipases that catalyze the hydrolysis of lipids—Enzymes

Step 1: Given data (part a)

Proteins are polymers of amino acids that are joined together by peptide bonds. In their structure, amino acids have both amine and carboxylic functional groups.
