What is Polymer of Amino Acids?

Polymer of amino acids or protein is an essential macromolecule that plays a critical role in our body. Proteins are made up of long chains of amino acids that are folded into complex shapes. There are 20 different types of amino acids that can be combined to form various types of proteins. The sequence of amino acids determines the unique function and properties of each protein.

Functions of Protein in Our Body

Protein is an important nutrient that our body needs to function properly. It performs various functions such as:

Structural Support

Protein provides structural support to the body by forming tissues, organs, and muscles. Collagen, a type of protein, is the most abundant protein in our body, and it provides strength and elasticity to our skin, bones, and tendons.


Proteins act as enzymes that catalyze chemical reactions in our body. Enzymes are responsible for breaking down food, producing energy, and synthesizing new molecules.


Proteins also act as hormones that regulate various physiological processes in our body. For example, insulin is a protein hormone that regulates blood sugar levels.


Proteins act as carriers that transport molecules like oxygen, carbon dioxide, and nutrients in our body. Hemoglobin, a protein found in red blood cells, transports oxygen from the lungs to the body tissues.

Sources of Protein

Protein is found in a variety of foods such as meat, fish, poultry, dairy products, beans, nuts, and seeds. It is important to consume a balanced diet that includes all types of protein sources to meet the daily protein requirement.

Protein Deficiency

Protein deficiency can lead to various health problems such as:


Protein deficiency can lead to malnutrition, which can cause stunted growth, weakened immune system, and delayed wound healing.

Muscle Wasting

Protein deficiency can cause muscle wasting, which can lead to weakness and fatigue.


Protein deficiency can cause edema or swelling due to the accumulation of fluid in the tissues.


In conclusion, protein is an essential nutrient that plays a critical role in our body. It provides structural support, acts as enzymes and hormones, and transports molecules in our body. It is important to consume a balanced diet that includes all types of protein sources to meet our daily protein requirement and avoid protein deficiency.
