Unit 2: Fats And Oils Flashcards
1
Q
Fats and oils are based on what
A
Based on glycerol, propane-1,2,3-triol
Esters of glycerol and long chain carboxylic acids
2
Q
Hydrocarbon chains
A
Can be from 4-24 C’s Long
Can be single bonded (saturated) or double bonded (unsaturated)
3
Q
Fat molecules
A
Packed together tightly, making fats solid at room temperature
4
Q
Oil molecules
A
Less tightly packed molecules make oils liquid because forces between molecules are weaker
5
Q
Hydrogenation
A
Addition of hydrogen to unsaturated oil “hardens” and increases melting point
6
Q
Glycerol and fatty acid ratio
A
1:3
