Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues
Amino acids are the building blocks of proteins. The beads (amino acids) are connected together by a string (bond), which forms a long chain (protein).
Therefore, a protein is "intact" or "whole." Proteins are connected together; free amino acids are not.
Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.
Proteins are made up of smaller building blocks called amino acids, joined together in chains.
There are 20 different amino acids. Some proteins are just a few amino acids long, while others are made up of several thousands. These chains of amino acids fold up in complex ways, giving each protein a unique 3D shape
They also assist with the formation of new molecules by reading the genetic information stored in DNA
