Proteins: Structure, Types, Sources, and Functions Explained
Proteins are essential macromolecules that play a vital role in every living organism. They are often called the "building blocks of life" because they are involved in nearly every biological process, from providing structure to cells to catalyzing biochemical reactions. This blog explores proteins in detail, covering their chemical composition, types, sources, structure, and biological functions . What Are Proteins? Proteins are organic compounds made up of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. They are polymers of amino acids linked together by peptide bonds . These macromolecules are essential for the growth, repair, and functioning of all living cells. Proteins are present in every cell, performing structural, enzymatic, transport, and regulatory functions. Composition of Proteins Proteins are composed of chains of amino acids, which are their building blocks. There are 20 standard amino acids that join in various sequences to form thousands of p...
