WebLarge biological molecules are generally composed of a carbon skeleton (made up of carbon and hydrogen atoms) and some other atoms, including oxygen, nitrogen, or sulfur. Often, these additional atoms appear in the context of functional groups. WebThe tertiary structure is the further folding of a polypeptide to give a more complex 3D shape. The shape is very precise and specific to the function of the polypeptide. The quaternary structure of a protein is if it is made of two or more polypeptides. Haemoglobin is an example with a quaternary structure because it has four polypeptides.
