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.

Peptide chain is a short chain of amino acids joined by peptide/amide bonds (covalent bond). The peptide bond is formed by the condensation of carboxyl group of one amino acid to the amine group of the another amino acid with release of water molecule. Each amino acids contains carboxyl group, amine group, hydrogen atom and side chain group. Based on the side chain amino acids can be charged polar, uncharged polar and non-polar.
Charge on the amino acids depends on it pKa values. pKa is the measurement of the acidity of any molecule or how tightly a proton is bound to it.
