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 an essential component of the cell membrane. The structure is typically made of a glycerol backbone, 2 fatty acid tails (hydrophobic), and a phosphate group (hydrophilic).
Detailed explanation-3: -In lipids, the components are the same but the ratio is less for oxygen, so it is 1:2: less than one for C:H:O.
Detailed explanation-4: -Lipids are composed of carbon, hydrogen and oxygen atoms, and in some cases contain phosphorus, nitrogen, sulfur and other elements.
Detailed explanation-5: -Carbohydrates (CHO) are composed of simple sugars (i.e. glucose, fructose, galactose) and are found mainly in plants (usually stored as starches or cellulose).
