Pls asap will give brainliest ! what are all proteins made of (this is called the primary structure)?

The overall three-dimensional structure of a polypeptide is called its tertiary structure. The tertiary structure is primarily due to interactions between the R groups of the amino acids that make up the protein. ... These include hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridge formation.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
