Lipids are made of ____
A
C H O
B
C H O N
C
C H O N P
D
C H O N S
Explanation: 

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). As such, phospholipids are amphipathic.

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 a diverse group of hydrophobic compounds that include molecules like fats, oils, waxes, phospholipids, and steroids. Most lipids are at their core hydrocarbons, molecules that include many nonpolar carbon-carbon or carbon-hydrogen bonds.

Detailed explanation-5: -Lipids include fats, oils, waxes, phospholipids, and steroids.
