Proteins are macromolecules that are polymers made of monomers called amino acids.
These monomers have very similar structures and differ from one another only by the radical group, or R group or side chain. The other two gruops are the carboxyl or carboxilic acid (COOH) and the amine group (NH2)
Some of these monomers have groups that fall into three categories: polar (hydrophilic) which means that is compatible with water; non polar (or hydrophobic) which means it is not compatible with water (typically amino acids are clasified only in these two categories). Both groupes are non charged, so the third group are the charged amino acids that could be positively or negatively charged. These charged aminoacids are typically hydrophilic too.
The monomers are joined together by the peptide linkage.
The carboxyl group of the first monomer is joined to the amine group of the next monomer.
The sequence of monomers from start to finish is called the primary structure of a protein. The other structures mentioned in the excercise are easily enough the secondary, tertiary and in more complex proteins, the quaternary structures., which describe from the inside to the outside of the protein, the 3D conformation.
The joining of protein monomers to form a polymer is called a condensation reaction. One H of the carboxyl and one from the amine groups are lost, the oxigen comes form the carboxyl group, to form the water molecule H2O.
