How to calculate percentages of arginine 's side chain have positively charge at PH=7
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.
Biochemistry : How to calculate percentages of arginine 's side chain have positively charge at PH=7
INTRODUCTION:
Arginine : It is an amino acid with the chemical formula CN(CH2)3CHCO2H. Its molecule has a guanidino group which is attached to a standard amino acid frame. At the physiological pH of the body, the carboxylic acid is deprotonated(-CO2-), and then both the amino and guanidino groups are deprotonated, which makes the molecule a cation.
Physiological pH : When there is no pathological state in the body, it works and functions at a pH ranging between 7.35 to 7.45, and the average pH is 7.4.
We can calculate the number of protonated and deprotonated groups in Arginine with the help of Henderson-Hasselbach equation.
