Introduction of Biochemistry | Bio-Molecules

What is Biochemistry? 

Term Biochemistry was first coined in 1903 by Carl Neuberg. Carl Neuberg was the founder of biochemistry.

Defination: Biochemistry is basically the study of chemical elements present in the living organisms and it is the study of dynamic processes taking place in living organisms.


Biochemistry as termed as biological chemistry or physiological chemistry. Carl Neuberg father of biochemistry studied the structure of biomolecules and the movement of soluble biomolecules inside or outside the cells.

In the middle of 1900s, the demand of biochemistry increased in the field of medication, microbiology, and nutrition. Biochemistry is concerned with the study of large chemical molecules like carbohydrates, lipids, and amino acids. It is also the study of functions and chemical construction of biomolecules within a living organism.


What are Biomolecules:

Biomolecules are that molecule that plays a vital role in the preservation and metabolic developments of living organisms. The human body is the collection of foremost elements such as carbon, hydrogen, oxygen, and nitrogen that combine to form a prodigious diversity of molecules called biomolecules. Due to the combination of the foremost elements four major complex biomolecules are formed that are named as, carbohydrates, proteins, lipids and nucleic acids. These molecules play a very vital role to distinguish the nature and functions of biomolecules.`


Biochemistry of Bacterial cell and Mammalian cell.

All living organisms made of organic compounds such as carbohydrates, proteins, lipids and nucleic acids. Among inorganic substances are carbon dioxide, water, acids, basis, and salts.

Typically, an animal cell and bacterial cell consist of following chemical compounds as shown in the chart:
