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)
