The order of amino acids can affect the protein's shape.
It allows the amino acids the ability to accept or donate protons to facilitate reactions as well as to form ionic bonds.
This is how Diversity is obtained.
primary structure
Peptide sequence or amino acid sequence is the order in which amino acid residues, connected by peptide bonds, lie in the chain in peptides and proteins. The sequence is generally reported from the N-terminal end containing free amino group to the C-terminal end containing free carboxyl group. Peptide sequence is often called protein sequence if it represents the primary structure of a protein.
Amino acids---->peptide---->polypeptide--->protein.
Amino acid = Smallest building block of proteins; 20 of them. In this order. Amino acid < dipeptide ( two peptides ) < polypeptide (many peptides ) < Protein
Primary protein structure is the order of amino acids that compose the protein and their arrangement into 2 dimensional structures like sheets or helixes is secondary. Tertiary structure is the mixed composition of secondary forms to make a three dimension protein and quaternary structure is how the protein becomes part of a functional unit like hemoglobin inside of a blood molecule.

The order of amino acids in a protein determines its structure and function.

The sequence of nitrogenous bases (A, T, G and C) forms a code for the sequence of amino acids in a protein. The code is a triplet code. This means that three bases code for one amino acid. So, the order of the bases in a gene determines the order of the amino acids in a protein.

The four levels of protein structure are differentiated from each other by the complexity of their polypeptide chain. Proteins are constructed from 20 amino acids. The levels are the hydrogen atom, a Carboxyl group, an amino group and a variable or "R" group. They have a primary structure, the order in which the amino acids are linked to form a protein. Secondary structure , coiling and folding of the polypeptide chain. Tertiary structure, is a 3-D structure of a protein chain. Quaternary is the structure of a protein macro molecule formed by interactions between several polypeptide chains..

The R groups of the amino acids in its active site
Amino acid order is of great importance to a protein's function. Every amino acid has unique chemical properties that affect the function of a protein. In the case of an enzyme, those amino acids in the active site of the protein must be able to properly bond to the substrate, activate it chemically, and possibly put a certain amount of strain on the bonds within the substrate in order to make it more susceptible to a chemical reaction. And in the case of other functional proteins (such as receptors or muscle protein), the amino acids in the bonding site must similarly be of the right type so that bonding of various substrates can cause the right change in the shape of the protein. Additionally, the amino acids in the nonactive areas of the protein must be such that the protein folds properly.
