Flashcards in CH5 fats Deck (36):
1

Saturated fat

no double bonds
raises blood cholesterol
solid at room T-lard, butter, meat fat

2

Mono unsaturated fat

one double bond (lack H atom)
lowers bad cholesterol, lower risk of Heart disease
Liquid at room T- olive oil

3

poly unsaturated fat

more that one double bond
reduce bad cholesterol levels
liquid at room Tem solid when chilled-salmon

4

transfat

hydrogen atoms added to unsat fatty acids
increase risk of cardio disease

5

triglycerides

1 glycerol and 3 fatty acids
stored in fat cells
released between meals for energy

6

chylomicron

lipoprotein produced in enterocyte to transport lipid from a meal
composed of fatty acids surrounded by phospholipids & proteins
soluble in water

7

micelle

capture lipid digestion products and transports them to enterocyte for absorption

8

Functions of lipids in body

protect, insulate organs
fat soluble vit, regulates cell function
maintains membrane
nerve cell transmition

9

structure of all fatty acids

carboxyl group COOH

10

2 essential fatty acids

linoleic acid
alpha liolenic acid

11

Linolenic acid Essential Fatty acid

omega 6 fatty acid
vegetables and nuts

12

Alpha linolenic acid Essential Fatty acid

amega 3 fatty acid
vegetables, soy, flaxseed
walnuts oil fish

13

triglycerides

omega 3 fatty acids found in fish and oil
eicosapentaenoic acid EPA
docosahexaenoic acid DHA

14

triglycerides

protect against cardio disease
stimulates prostaglandins and thromboxanes that reduce inflamatory response
reduce blood clotting and plasma trilycerides

15

sterols

multiple rings of carbon atoms
secrete cholesterol

16

bile

emulsifies fat
made in liver
stored in gallblader

17

cholesterol

synthesized in liver
used to make hormones
vit D
and bile

18

Very Low Density Lipoproteins

produced in liver and small intestine
transport tryglycerides into blood stream

19

Low Density Lipoprotein

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

20

High Density Lipoprotein

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

21

blood lipids normal range
total

<200mg/dl

22

blood lipids normal range LDL

Bad cholesterol
<100 mg/dl

23

blood lipids normal range HDL

good cholesterol
more than or = to 60 mg/dl

24

blood lipids normal range tryglicerides

<150 mg/dl

25

LDl

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

26

HDl

released in liver and small intestine
high level-> low risk of cardio disease

27

relation betwwen sat fat, cholesterol, and chronic disease

sat and trans fat
decease removal of LDL's from blood
increase Cholesterol level in blood
forms plaques that blocks arteries

28

Sat fat %

less than 7%

29

unsaturated fat

20-35 %

30

total fat

20-35%

31

hydrogenation

addition of H atoms to unsaturated fats (creates trans fat)
-helps reduce oxidation and resist rancidity
-risk of cardio disease

32

CCK role in digestion

along with secretin
produce gallbladder contraction to release bile

33

fiber does to fat

fiber eliminates ___ from bady

34

triglycerides storage

adipose tissue

35

(alpha linolenic acid) make
omega 3 fatty acids

DHA and EPA

36
