\nProteins have different types of structures. The primary structure refers to the sequence in which the various amino acids present in the proteins are linked to one another in the polypeptide chain. This sequence of amino acids is determined by mRNA. \nSecondary structure refers to the helical structure (left-handed helices and right-handed helices) of proteins. The alpha or beta helical structure is stabilized by hydrogen bonds. Alpha and beta-pleated sheet organization is an example of the secondary structure of a protein. \nThe tertiary structure of a protein refers to the overall three-dimensional view of protein. It includes bending and folding of long polypeptide chains to form a hollow woven ball-like structure. The structure is stabilized ‘H’ bonds, disulphide linkages, Van der Waals and electrostatic forces of attraction (ionic) etc. \nThe quaternary structure of a protein is an assembly of more than one polypeptide chain or subunit. A linear string of spheres, spheres arranged one upon each other in the form of a cube of plate etc., is the architecture of a quaternary structure of the protein. It also contains a hydrogen bond. \nEssential amino acids are not synthesized in the body of animals, so they are must be provided in the diet, whereas non-essential amino acids are synthesized in the animal body. \nThe most abundant protein in the whole biosphere is RuBisCO, and in the animal world, it is collagen.
