1

catabolism

burning/breaking down

2

anabolic

building up

3

3 stages of catabolism of food

1. break down into monomers
2. convert monomers to acetyl coA or another piece of citric acid cycle
3. feed into the citric acid cycle and gain energy

4

3 stages of anabolism

1. produce precursors such as aa, monosaccharides and nucleotides
2. activation of those precursors into reactive forms using ATP phosphorylation energy
3. assemble activated precursors into complex molecules such as proteins, polysaccharides, lipids, and NA

5

3 examples of complex carbs

cellulose, starches, glycogen - have more fiber and higher nutritional value

6

2 examples of simple carbs

glucose - monosaccharide, sucrose - disaccharide

7

what are linoleic and linolenic acids modified to make?

eicosanoids

8

what do eicosanoids effect

inflammation and other cell functions

9

is linoleic (w-6) usually Add to dictionary?

yes

10

what is linolenic (w3) usually?

anti-inflammatory

11

lipoids

molecules formed from linoleic acid(w6), Add to dictionary

12

resolvins

formed from linoleic acid (w6), down regulate inflammation especially in the presence of ASA

13

endocannabinoids effect what

affecting appetite, pain sensation mood and memory

14

what forms lipid rafts?

linoleic and linoleic acids

15

examples of omega 3 foods

sardines, salmon, flax seed, walnuts etc..

16

What specific pt populations may benefit from omega 3 rich diet?

depressed, inflammatory problems (CVD, fatigue, dry itchy skin, jt pain), DM2, brittle hair and nails, inability to concentrate

17

how many essential aa are there?

9 , example tryptophan

18

what is an example of a conditional aa?

tyrosine

19

what is a conditional aa?

aa that can be made, but not fast enough.. these become essential in times of illness stress or poor nutrition

20

how many calories recommended from fat?

less than 1/3

21

what is PRO recommendation

55-75 grams

22

what is sodium recommendation

less than 2300mg per day

23

what are 3 main factors that play into perceiving hunger

increases plasma glucose, stress, conditioned response

24

in the absorptive state is anabolism or catabolism rate higher?

anabolism

25

t/f the absorptive state is insulin dominant

true

26

besides storing chylomicrons what other roles do they play?

burned for energy in liver, muscle, and fat cells

27

during the absorptive state what converts glucose into TG

liver AND FAT CELLS THEMSELVES

28

post absorptive state is aka

fasting state

29

when does post absorptive state occur?

3-5 hours after absorption

30

what glucose level is normal or maintained

70-110mg / dl
