BIOMOLECULES
Elements present in Biomolecules & Carbohydrates, Lipids, Protein and Nucleic Acid
INTRODUCTION :
What keeps the world dynamic and alive are the diverse living organisms living in it. These organisms
are composed of cells that work together to perform life-changing processes.
A huge array of molecules is present in the cell. The structure of each molecule determines the
chemical reactions it is able to participate and the role it plays in the cell’s life processes. These molecules
produced by living organisms are called biomolecules.
Biomolecule, also called biological molecule, any of numerous substances that are produced by cells
and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of
functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.
Biomolecules are all biological materials exclusive of cells and structural proteins when they are used
as the “natural biomaterials” themselves. Biomolecules include proteins, lipids, etc., and can serve various
functions like providing structural integrity to the tissue-engineered constructs. These include various growth
factors, differentiation factors, and angiogenic factors essential in all categories of tissue engineering along
with bone morphogenic proteins with a broad range of functional properties. Many biomolecules may assist the
host with various functions like may support cell attachment, cell growth (or apoptosis), cell differentiation, cell
migration, neovascularization, etc. All the functions indeed may be performed differently according to the
biochemical, cellular, and biomechanical behavior.
Most biomolecules are organic compounds, and just four elements—oxygen, carbon, hydrogen,
and nitrogen—make up 96% of the human body's mass.
Biochemistry aims to explain biological form and function in chemical terms. One of the most fruitful
approaches to understanding biological phenomena has been to purify an individual chemical component, such
as a protein, from a living organism and to characterize its chemical structure or catalytic activity. As we begin
the study of biomolecules and their interactions, some basic questions deserve attention. What chemical
elements are found in cells? What kinds of molecules are present in living matter? In what proportions do they
occur? How did they come to be there? In what ways are the kinds of molecules found in living cells especially
suited to their roles?
Types of Biomolecules
There are four major classes of Biomolecules – Carbohydrates, Proteins, Nucleic acids and Lipids. Each of
them is discussed below.
