Q

Carbon chain lengths

A

Short: 4 or less

Medium: 6-12

Long: over 14

1
Q

What is a tricyceride made up of ?

A

3 fatty acids

One glycerol

2
Q

Characteristics of chain length

A

The longer the carbon chain the more solid it becomes at room temp

3
Q

What makes an unsaturated fatty acid

A

Double carbon bond

4
Q

How do trans fatty acids form

A

Cis goes through processing such as heat to form trans fat

5
Q

What are the essential fatty acids

A

Omega 3 and 6

6
Q

Which omega is pro/ anti inflammatory

A

Omega 3 - anti inflammatory

Omega 6 - pro

7
Q

What does 18:4n-6 show

A

18 carbon atoms

4 double bonds

Omega 6

8
Q

What does different ratios of n3/n6 cause

A

Different cell mediators to be produced

Higher 3 reduce inflammatory response which could have health benefits

9
Q

Ratio of 6/3 in Palaeolithic diet vs modern

A

1: 1
20: 1

10
Q

Omega 3 sources

A

Oily fish
Flax seeds
Hemp seeds
Walnuts

11
Q

Omega 3 supplementation

A

Mda indicates amount of damage

Fish oil increases mda

12
Q

What do lipoproteins do

A

Transport substances

13
Q

Examples of lipoproteins

A

Chylomicions

Very low density lp
Low density lp
High density lp

14
Q

Why are low density lipoproteins or ldl seen in a bad light

A

Stay in blood for longer increasing the chance they become wedged in a vesicles

15
Q

What do HDLs do

A

Reverse the cholesterol transport

16
Q

What is and what does HSL do

A

Hormone sensitive lipase

Converts tg’s into fatty acids and glycerols

17
Q

What is lipolysis and lypogenisis

A

Lipolysis- conversion of triglycerides into FA and glycerol

Lipogenesis - reverse process

18
Q

Why does exercise increase lipolysis

A

Exercise increases hormones which stimulates HSL

19
Q

What do the following things do and what are they

FABP
FAT
CPT

A

Transport FA into the cells

Fatty acid binding protein
Fatty acid translocase
Carnotineparmataltranspotase

20
Q

What regulates fat oxidation

A

Fat availability
Transport of FA
Oxidative capacity

21
Q

Why is fat not use in high intensities

A

Cho oxidation is much faster

22
Q

What happens to FFA during exercise

A

Increases

23
Q

When is fat oxidation highest

A

65% vo2 max

24
Q

Who was higher fat oxidation females or males

A

Females through all intensities

25
Q

After trying what increases in terms of fat and why

A

Triglycerol use and to spare glycogen

26
Q

Why happens to FFA after training

A

Better uptake due to more FA transporter

27
Q

Why are medium chain FA more available

A

They only have to go from intestine to liver to muscle

28
Q

What does a high fat diet do

A

Increase fat oxidation

Increases per curved exertion
