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.
What types of covalent modifications commonly alter the
activity of proteins?
The DNA (deoxyribonucleic acid) is the genetic material of an organism that is passed on from the parent generation to the progeny. The DNA is transcribed to from the RNA (ribonucleic acid). The translation of RNA forms amino acids. Proteins are polymers of amino acids. Covalent modifications refers to the alterations created by enzymes on the protein structure that leads to removal or addition of chemical groups to the protein structure.
