Two questions:
1. What are the 2 major functions of proteins?
2. Describe the structure of proteins.

1-Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.

2-The overall structure of the protein includes both alpha helices (green) and beta sheets (red). The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape.
