What are macromolecules and its importance

What are macromolecules

Macromolecules are large amounts of molecules that are formed by the polymerization reaction. It is also possible to manufacture polymer chains emitted from the polymer material.

These polymorphic materials are called monomers. Our body is made up of these macromolecules.

Creating Macromolecules

When many polymers are added, macromolecules are formed. This process is called dehydration synthesis. One leaves one monomer hydroxyl (OH) ion group and the second leaves the monomer-H ion.

Then the polymer is broken down by a process called hydrolysis. Bond between monomer is broken by water (H2O).

Important macromolecules for life

Macromolecules are important for our four types of life, which are as follows:


It is a type of biological mixture that is composed of oxygen, carbon and hydrogen molecules. Carbohydrate found in human body is a group of glucose or skeleton, which is called monosaccharide.

These are very important for us biologically because they work to preserve the different types of energies. Carbohydrate is cured by eating cereals, fruits, vegetables and so on.

When many skins are added together, polysaccharide is formed. Starch is a type of polysaccharide that acts as an energy storage plant. Through the hydrolysis process, the plants collects a sucker or glucose for themselves.


These are a large group of molecules. Inserting vitamins include fat, fatty acids, sterols, steroid hormones, cholesterol, etc. The most important function of lipid is to keep energy stored and stored.

Many carbon and hydrogen bonds are found in lipid, which makes them very high in energy. They can put a lot of calories in a small space.

They can not dissolve in water and are found in various forms in human body. These are essential for maintaining the structure of the cells.

nucleic acids

These are one type of biological molecules and are made up of DNA and RNA. These are made of monomer named Nucleotide.

Genetic instructions are found within the DNA which are important for all living organisms to live and body processes.

Genetic instruction found in DNA by RNA is converted into proteins. It has three parts: phosphate, pentose sugar and nitrogenous base.


These are complex organic compounds that are made up of amino acids polymers. It is helpful in the formation of tissues and muscles.

When we take protein by eating, then the body turns the protein into amino acids with the help of enzymes found in the stomach. Amino acids then make other types of proteins, which help in the maintenance of blood, bone, muscles and other organs.

Proteins are also responsible for the composition of our body cells, due to which our memory, hormone, speed etc. are functioning smoothly. Protein is found in many foods such as meat, egg, pulses, soybean etc.
