Explanation: A chemical formula of a protein or any compound is the representation of the number of atoms of each element present in that protein or compound using chemical symbols and numbers. A symbol of an element consists of either the initial letter or the initial letter with one small letter from its name. Examples: symbol of carbon atom is C and the symbol of calcium atom is Ca.
