lipids and Cardiovascular disease Flashcards
(16 cards)
a kind of lipid
Triglyceride
Triglyceride structure
one glycerol and 3 fatty acid
Fatty acid have long tails made from hydrocarbon
Tails are hydrophobic (water repelling)
tails make lipids insoluble
Triglyceride are formed by
Condensation reaction
the fatty acid and glycerol are joined tg by
ester bonds
what are the 2 types of lipids
Saturated
Unsaturated
Saturated lipids are mainly found in
animal fats
Unsaturated lipids are mainly found in
plants
which type of lipids melts at lower temp
Unsaturated
saturated
no double bonds between carbon atoms
Unsaturated
double bonds between carbon atoms - cause the chain to kink.
Kink = bend
This kink prevents the molecules from packing closely together, making the lipid more fluid (e.g. in cell membranes).
High blood Cholestrol inc
risk of CVD
Cholestrol is a type of
lipids
what needs to be attached to the cholestrol and why?
protein, to move. so the body forms lipoprotein
2 types of lipoprotein
High density lipoprotein
Low density lipoprotein
HDLs
mainly proteins
transports cholestrol from body tissue to liver where its recycled
It reduces total blood cholesterol when the level is too high
LDLs
mainly lipids
transports cholesterol from the liver to the blood
It inc total blood cholesterol when the level is too low
