Question 16

bile

Answer 16

emulsifies fat
made in liver
stored in gallblader

Question 17

cholesterol

Answer 17

synthesized in liver
used to make hormones
vit D
and bile

Question 18

Very Low Density Lipoproteins

Answer 18

produced in liver and small intestine

transport tryglycerides into blood stream

Question 19

Low Density Lipoprotein

Answer 19

made by removal of all VLDL’s trigliceryde load
rich in cholesterol- taken to cells with LDL receptors
LDL not taken up be cells- taken up by live for degeneration

Question 20

High Density Lipoprotein

Answer 20

Produced in liver & circulates in blood
Picks up chol from dying cells , other lipptns
and arterial plaques
return cholesterol to body-> then recycles or eliminates from body through bile

LDl

Answer 25

Increases Blood cholesterol
Increases risk of cardio disease
oxidise->atherosclorosis

Question 26

HDl

Answer 26

released in liver and small intestine

high level-> low risk of cardio disease

Question 27

relation betwwen sat fat, cholesterol, and chronic disease

Answer 27

sat and trans fat
decease removal of LDL’s from blood

20-35 %

Question 30

total fat

Answer 30

20-35%

Question 31

hydrogenation

Answer 31

addition of H atoms to unsaturated fats (creates trans fat)

• helps reduce oxidation and resist rancidity
• risk of cardio disease

Question 32

Answer 32

along with secretin

produce gallbladder contraction to release bile
