What atoms make up proteins?

Some globular proteins can also play structural functions, for example, actin and tubulin are globular and soluble as monomers, but polymerize to form long, stiff fibers that make up the cytoskeleton, which allows the cell to maintain its shape and size. Other proteins that serve structural functions are motor proteins such as ... read more

Proteins are made up of monomers called amino acids which contain; Nitrogen (N), Carbon (C), Hydrogen (H) and Oxygen (O). Some also contain Sulfur (S) or phosphorous. read more

In brief, proteins are made up of monomers called amino acids. These amino acids are molecules composed of atoms of carbon, hydrogen, nitrogen, oxygen, and in some cases, sulfur. Amino acids, the monomers, are connected via peptide bonds, to form the polymer that is the protein. read more
