Detailed explanation-1: -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).
Detailed explanation-2: -Lipids are organic compounds that contain the same elements as carbohydrates. In carbohydrates the C:H:O is 1:2:1, this is why they are called carbohydrates, carbon, and hydrous, which is water.
Detailed explanation-3: -Lipid of any type contains the same structural elements as carbohydrates (Carbon, Hydrogen, and Oxygen). However, in lipids, the ratio of hydrogen to oxygen is considerably greater. For example, the common lipid, stearin, has as many as 18 hydrogen atoms for every oxygen (see figure below).
