Although all of these may play a part, the major driving force in protein folding is: a) hydrogen bond formation b) salt bridge formation c) steric interactions d) the hydrophobic effect A partially folded protein is called a a) peptide template b) active domain c) molten globule d) precursor protein Which of these processed is NOT seen in protein denaturation? A) subunits are dissociated b) folding is unraveled c) alpha helix and beta sheets are unraveled d) peptide bonds are 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.
