Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.
Proteins - structures, chemical bonding, denaturation, types of proteins. Read and learn more about proteins.
Proteins are molecules that support everything your body does. From helping you flex your muscles to breaking down nutrients in the foods you eat, proteins are hard at work.
Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another.
Proteins are large molecules made up of chains of amino acids that are important for cell function, tissue structure, and body regulation. Most people in the U.S. consume more protein than needed, with dietary guidelines suggesting about 6.5 ounces per day for men and about 5 ounces for women.
Proteins provide many of the structural elements of a cell, and they help to bind cells together into tissues. Proteins, in the form of antibodies, protect animals from disease, and many hormones are proteins. Proteins control the activity of genes and regulate gene expression.

Proteins are large, complex molecules that play many important roles in the body. They are critical to most of the work done by cells and are required for the structure, function and regulation of the body’s tissues and organs.
