Which of the following statement about proteins is correct a. alpha helix and Beta pleated sheets are considered quaternary structures b. a single polypeptide only has primary sytructure, secondary, tertiary, and quaternary structures require more than one polypeptide c. there are 30 essential amino acids that are the monomer building blocks of proteins d. polypeptides have a distinct polarity (directionality) with one end refered to as the free amino end, and the other called the free carboxyl end
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.
