prod. by plants through photosynthesis

lactose
Dissachride
glucose and galactose
Maltose

Disaccharide
glucose and fructose
carb absorption in villi
Additional enzymes digest disac to mono
mono- absorbed into mucosa cells lining the small intestine then to bloodstream then to liver
carb absorption and release
Bdown fructose and galactose to glucose
if needed immediately for energy- glucose released to blood stream
carb storage
if glucose not needed it is stored as glycogen in liver and muscles
ratio of CHO in carb
CH2O
glucose role in cell
red blood cells
only use glucose for energy
used to maintain blood glucose
Insulin resistacnce
cell becomes less responsive to insulin
-When too much glucose inside cell- cell gets removs insulin receptors
cells stop making receptors preventing glucose into cell and causing hyperglycemia
