Building Blocks of Proteins

Proteins are essential biological molecules that perform a variety of functions within living organisms. They are made up of smaller units called amino acids, which are linked together by peptide bonds. Each protein has a unique sequence of amino acids that determines its specific structure and function. One common type of protein is an enzyme, which catalyzes biochemical reactions. Understanding the building blocks of proteins is fundamental in biology.
