Differences Between Fatty Acids

What do saturated fatty acids not have?

A double carbon bond

What are the carbon atoms completely saturated with in a saturated fatty acid?

Hydrogen atoms in their structure

What mostly contains saturated fatty acids?

Mostly animal fats (except fish)

What do many plant oils contain?

Monounsaturated fatty acids

What do avocados, vegetables oils, nuts or fish contain?

Polyunsaturated fatty acids

What types of double bonds do unsaturated fatty acids contain?

Unsaturated fatty acids can have one (monounsaturated) or several double carbon bonds (polyunsaturated)

What does having more double bonds mean?

The more kinks the hydrophobic tail has

What does the amount of kinks in the hydrogen tail affect?

The packing of the fatty acids and the number of hydrophobic interactions (weak chemical forces of attraction) can be formed between them

What does the more saturated fatty acids have?

• A higher melting point

• Packed more densely and can form more bonding interactions between them

• More forces of interaction needs more energy to break
