Amino Acids are joined by peptide bonds. ... Once all the amino acids join together or connect by peptides bonds, they form a sequence of amino acids also known as a polypeptide chain that become the primary structure of a protein. ... Disulfiede bridges are made by disulfide bonds. Disulfiede bonds are covalent bonds that usually come from the coupling of two think groups. The disulfide bridge is formed when the sulfur atom from one cysteine forms a single covalent bond with a sulfur atom from a second cysteine in a different part of the protein. ...

It is connected by peptide bonds, and the sequence determines the structure and shape of the whole protein. ... All covalent links in a protein are included in the primary structure. ... A beta pleated sheet is a form of shape where the bonds create a kinked shape, and attract across the space, as in the diagram overleaf. ... Various types of bonds are used in these links: hydrogen bonds between R groups, disulphide bonds between two cysteines molecules, as in the primary structure, ionic bonds between R groups containing amine and carboxyl groups, and hydrophobic reactions between R groups wh...
