Question

Which information could a student determine from only the chemical formula of a protein? A) The color of the protein B) The number of molecules in each sequence that makes up the protein C) The physical arrangement of atoms in the structure of the protein D) The number of atoms of each element of the protein

Answer 1

Answer: D) The number of atoms of each element of the protein

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. In writing chemical formula of a compound, the number of atoms of an element present in the compound is usually written as a subscript to the symbol of that element. Example: The chemical formula of glucose is C6H12O6, this means that there are six carbon atoms, twelve hydrogen atoms and six oxygen atoms in one molecule of glucose.
