Detailed explanation-1: -Carbohydrates and proteins are two types of macromolecules. Which functional characteristic of proteins distinguishes them from carbohydrates? nucleic acids. unable to catalyze reactions.
Detailed explanation-2: -Proteins are different from fats and carbohydrates due to the presence of nitrogen, carbon, hydrogen, and oxygen in them. Carbohydrates only contain carbon, hydrogen, and oxygen whereas fats contain fatty acids which contain a carboxyl group and an alkyl group, thus containing only carbon, oxygen, and hydrogen.
Detailed explanation-3: -If all three nutrients are abundant in the diet, carbohydrates and fats are used mainly for energy while proteins help make hormones, muscle and other proteins. Proteins in food are broken down into pieces called amino acids.
Detailed explanation-4: -The chemical structure of proteins contain carbon, hydrogen, oxygen, and nitrogen, while the chemical structures of carbohydrates and fats contain only carbon, hydrogen, and oxygen. Carbohydrates and fats do not contain nitrogen while protein does contain nitrogen.
