Naming the fats properly:
Oic acid
En
Di
Tri

Fatty acid
Double bonds
2 Number of double bonds
3 Number of double bonds

1

Linoleic acid

18:2w6

2

Linolenic acid

18:3w3

3

Arachidonic acid

20:4w6

4

Eicoapentaenoic acid

20:5w3

5

Docosahexaenoic acid

22:6w3

6

Palmaric acid

16:0

7

Stearic acid

18:0

8

Oleic acid

18:1w9

9

MAG

Monoacylglycerol

10

DAG

Diacylglycerol

11

TAG

Triacylglycerol three fatty acids attached to glycerol

12

A fatty acid

Carboxyl group and carbon chain

13

Acyl definition

An organic radical derived from an organic acid by the removal of the carboxylic hydroxyl group
Fatty acid attached to something

14

Acyl-CoA

Fatty acid attached to coenzyme A

15

Acyl carrier protein

Enzyme portion of fatty acid synthase
It holds an acyl group

16

Fat storage

TAGS
Three fatty acids on a glycerol ( saturated unsaturated or both)

17

Energy dense triglycerides

Reduced (lots of electrons)
Anhydrous (no water)
9kcal

18

Glycerol is attached to what chain

Long chain fatty acid

19

TAG broken down by what enzyme

ATGL

20

DAG Broken down by what enzyme

HSL

21

MAG broken down by what enzyme to form a free fatty acid

MGL

22

Lipoproteins are transported in the blood to where

Muscle and adipose tissue

23

What hydrolyzes TAGs

Extracellulsr enzyme LPL

24

Where is LPL produced?

Muscle and fat cells and must find its way to the lumen of the capillary (produced by target cells)

25

Lipoprotein lipase breaks down what

Breaks down surface of capillary(mostly skeletal muscle heart and adipose tissue)
Fatty acid
Glycerol

26

Lipoprotein lipase and muscle

FA oxidizes for energy

27

Lipoprotein lipase and adipose tissue

Re-esterfied to be store as TAGS

28

Lipoprotein lipase and exercise

Results in increase in skeletal muscles LPL

29

Diet and excess FA in the diet

Liver converts excess into VLDL
transported I. Blood to adipocytes
TAG removed (stored in lipid droplets)

30

Lipid droplets are what

Neutral lipids presents in cells especially adipocytes and are steroid synthesizing cells (adrenal cortex ovary testes)

31

Lipid droplets are where

Present in almost all cells

32

Where are TAG mostly stored

Larger amounts are in Subcutaneous and viscera, adipose tissue while smaller amounts are in Skeletal muscle fibers (1-2%)

33

Type I fibers have more...

Aerobic more mitochondria (oxidize more FA) store 2-3x more fat the Type II

34

IMTGs...

Fat storage depot if there are a lot of lipids available and are a source of FA to be used during exercise (increased energy expenditure)

35

IMTGs and normal populations

Have lower IMTG concentration and moderate insulin sensitivity

36

IMTG and athletes

Have elevated oxidative capacity higher concentrations of IMTG and greater insulin sensitivity

37

IMTG and obese individuals

Have higher IMTG concentration and low insulin sensitivity

38

Exercise ... IMTG

Decreases

39

IMTG Post exercise ....

Increases
