4. The interactions on the backbone (not the side chains) contribute to the (circle one): primary/secondary/ tertiary/quaternary structure of the protein. On your drawing for #3 indicated the partial charges on the atoms near the new covalent bond. For alpha-helix, these atoms of opposite partial charges that are four amino acids away are interacting to form bonds. 5. The interactions between side chains contribute to the primary/secondary/tertiary/quaternary (circle one or more) structure(s) of the protein. 6. What happens when you denature a protein with heat or pH changes? Which bonds are most likely broken?

Proteins

We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.  

Protein Expression

The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
