Which of the following statements about alpha-helix and beta-sheet structure are true? More than one answer is correct. -they are aspects of protein secondary structure. -they are maintained by hydrogen-bonding interactions within the polypeptide backbone. -most proteins fall into one of two categories: those composed entirely of alpha-helix, and those composed entirely of beta-sheet. -in both alpha-helix and beta-sheet, each amino acid (at position n) interacts with another amino acid at position n+4. -alpha-helix contains only hydrophobic amino acids, while beta-sheet contains only hydrophilic amino acids

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.
