6. Hair, primarily made of a-helical Keratin protein, grows at a rate of ~ 15 cm/year. Based on your knowledge of an a-helix (pitch and # of amino acids per turn), calculate the rate at which peptide bonds must be synthesized (bonds per second) to account for the yearly growth of a hair follicle.
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.
Introduction :-
One member of the family of structural fibrous proteins known as scleroproteins is keratin. Vertebrates include the keratin type known as alpha-keratin. In vertebrates, it is the primary structural component of scales, hair, nails, feathers, horns, claws, and the outer layer of skin.
