Explanation:
Detailed explanation-1: -Carbon chains are principal features of both carbohydrates and lipids. What is the primary difference between these two types of macromolecules? Lipids always have longer carbon chains than carbohydrates.
Detailed explanation-2: -Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).
Detailed explanation-3: -Lipids contain the same elements as carbohydrates: carbon, hydrogen and oxygen (C, H, and O). However, lipids are mainly made of hydrocarbon chains (or rings) and contain fewer polar hydroxyl groups (-OH). This makes most lipids nonpolar hydrophobic molecules (they do not dissolve well in water).
