What is a "protein molecule"?
A protein molecule is a large, complex structure made up of one or more chains of amino acids, which are the building blocks of proteins. Proteins perform a variety of functions within living organisms, including speeding up metabolic reactions, copying DNA, responding to signals, and transporting molecules. Each protein molecule has a unique shape and function, determined by the order of amino acids and the way the molecule folds into its three-dimensional form. Proteins are essential for the structure, function, and management of the body's tissues and organs.
Example
