glucose
blood sugar; comes from digestion in liver(mono)
fructose
sugar in fruits; converted to glucose in the liver(mono)
galactose
combined with glucose to make milk sugar in mammary gland(mono)
sucrose
glucose+fructose; 25% of caloric intake for average american; table sugar (di)
lactose
glucose+galactose; milk sugar only; lactose intolerant= lack "lactase" enzyme (di)
maltose
glucose+glucose; smallest part of diet -- cereal, beer (di)
2 forms of polysaccharides
starch and fiber
starch
storage of CHO in plants; complex carbs; 50% of carb intake; grains, potatoes, corn;
amylose+amylopectin
fiber
mostly make up structural components in plans; can't digest!
exercise intensity on muscle fuel source
- high intensity = more carb
- low intensity = more fat
Carbohydrate fuel
1. blood glucose from liver
2. muscle glycogen
Fat Fuel
1. plasma free fatty acids (adipose tissue)
2. intramuscular triacylglycerols (IMTG)
Muscle fuel
1. Muscle glycogen
2. intramuscular triacylglycerols
Blood-borne fuel
1. plasma free fatty acids (adipose tissue)
2. blood glucose
low intensity vs. high intensity specific fuel sources
-low intensity: lacks muscle glycogen as fuel source so PLASMA FATTY ACIDS
-high intensity: MUSCLE GLYCOGEN!
Can muscle glycogen be transported?
NO! cannot be transported from one muscle to another
Glycogen
, - storage of CHO in animals
- long link of glucose molecules
- stored in liver and muscle
- liver glycogen -> blood glucose
- muscle glycogen-> local store of fuel for contraction
glycogen breakdown
1.glycogenolysis - glycogen -> glucose for fuel
2. glycogen is major source for high intensity
3. hit the wall when run out
muscle glycogen is key for performance
endurance!
CHO DISTRIBUTION:
1. plasma glucose (16 kcal)
2. liver glycogen (400 kcal)
3. muscle glycogen (1600 kcal)
what is the norm blood glucose level before exercise?
5 mM -- continues to decrease with exercise
order of energy source during exercise:
1. muscle glycogen
2. IMTG
3. blood glucose
4. plasma fatty acids
gluconeogensis occurs more than glycogenolysis during exercise. (T or F)
FALSE! break down of glycogen in liver happens way more than generation of glucose
from other sources
higher intensities of exercise lead to more glycogenolysis
true
gluconeogenesis
- happens in liver
- lactate can leave muscle and go to liver to be converted to glucose
liver produces 2 times as much glucose in intense exercise vs. rest (T OR F)
TRUE!
does glucose uptake increase or decrease with increase exercise intensity
increase!
ROLE OF CHO IN BODY
- brain uses almost only glucose for fuel
- primary fuel for muscles during exercise
- difficult to maintain intensity with depleted sugar levels
LIPIDS
- 3 kinds: simple, complex, and derived
- dietary fat = triglycerides
- same elements as carbs but linked differently
lipolysis
-triglyceride broken down to release fatty acids for energy
lipase
enzyme needed to break down triglycerides by adding H20
