When we refer to the backbone of a polypeptide, we are referring to the attachment between: Select one: O a. The amino, carboxyl group and the a-carbon O b. The peptide bond between two amino groups O c. The amino acids making the polypeptide O d. The amino and carboxyl groups only O e. The R groups of the amino acids Which of the following molecules is a polymer made from large number of building blocks called monomers linked together by covalent bonds? Select one: O a. Glucocorticoids, a steroid hormone O b. Waxes (such as beeswax) O c. Glycogen, that stored in liver cells O d. Cooking oils O e. Stearic acid (saturated fatty 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.
