Answer:
They have approximately similar molecular weight, chemical composition and solubility.
Explanation:
Macro molecules are bigger molecules having more weight. The molecular weight of the macro molecules is more than 10,000 Dalton. They are chiefly the carbohydrates, proteins, lipids, and nucleotide. These are found in the acid-insoluble pool. This means all macro-molecules are acid insoluble. They are all polymers. Their composition is similar, having carbon and hydrogen which forms bonds with other compounds like nitrogen, sulphur, phosphate, OH, etc. They are all basic components of the cell and cell membrane and all are organic molecules.
