fatty acid monosaccharide
is a building block of phospholipids
contains oxygen
has carbon atoms arranged in a ring

Question

Accepted Answer

# Brief Explanations:
- **Is a building block of phospholipids**: Phospholipids consist of glycerol, two fatty acids, and a phosphate - containing group. So, fatty acid is a building block of phospholipids ($✓$), while monosaccharides are not ($✗$).
 - **Contains oxygen**: Both fatty acids ($C_{n}H_{2n}O_{2}$) and monosaccharides ($C_{x}(H_{2}O)_{y}$) contain oxygen. So, both get a $✓$.
 - **Has carbon atoms arranged in a ring**: Monosaccharides (e.g., glucose has a ring - structure in its cyclic form), while fatty acids have a linear hydrocarbon chain with a carboxyl group at the end. So, monosaccharide has carbon atoms arranged in a ring ($✓$), and fatty acid does not ($✗$).

# Answer:
|  | Fatty acid | Monosaccharide |
|--|--|--|
| Is a building block of phospholipids | $✓$ | $✗$ |
| Contains oxygen | $✓$ | $✓$ |
| Has carbon atoms arranged in a ring | $✗$ | $✓$ |
