Question

Accepted Answer

Basis of differentiation

Lipids

Fats

Definition

Are a class of organic molecules that are soluble in organic solvents but insoluble in polar solvents including water

Are an oily substance found in the body, under the skin or around the organs

Source

Are derived from plant sources such as seeds, nuts, and olives

Are derived from animal sources such as eggs, meat, and dairy

Correlation

Are a diverse group of biomolecules found in the animal body

Are a type of lipids

Physical Status

May occur as solid or liquids

Occur as solid substances

Solubility

Are soluble in organic solvents but not in polar solvents such as water

Is soluble only in non-polar solvents and insoluble in polar solvents

Types

3 types:

Triglycerides 
Phospholipids 
Steroids

2 types:

Saturated fat 
Trans fat

Function

Serve as energy storage reservoir  
Is a structural component of cell membrane
Transmit signals from one part of the body to another
Provide insulation and cushioning to internal organs

Are used as an energy source
Provide the body with insulation
