Saturated fats definition (4)

Are not kinked within the structure (no C=C in carbon chain) and are saturated with many hydrogen atoms 

Solid at lower temperatures

Provide rigidity and less fluidity

Hydrophobic

Unsaturated fats definition (3)

Less saturated, meaning they have less hydrogen atoms because attached, because C=C in chain takes away bonding possibilities

Provide more fluidity to plasma membrane 

Trans definition

Straight saturated hydrocarbon chain

Trans = inflexible and straight

Heated cis becomes trans 

Cis definiton

Bent saturated hydrocarbon chain 

Has a double bond C=C 

Heated cis becomes trans 

Difference between monounsaturated and polyunsaturated fat 

mono = one C=C

poly = two or more C=C

Common features of lipids (3)

Hydrophobic

soluble in ethyl ether & chloroform -> non-polar solvents

Contains many hydrocarbons (chain or ring structure)

Composition of fatty acid (3)

Carboxylic acid group on one end (COOH, makes it fatty acid), hydrocarbon chain, methyl group on other end (CH3)

What are implications (effects) on having glyceride rich diet?

Obesity & Atherosclerosis (hardening of arteries)
