describe carb digestion throughout the system
in the mouth, saliva begins chemical digestion of carbs. nothing happens to carbs in the stomach. in the small intestine carbs are broken down to monosaccharides before they are absorbed and then carried into the liver where the liver will turn it into energy. If no energy is needed it will put it into glucagon storage and is those are full then it will store it as fat.

glucose galactose fructose

glucose and fructose
31
what is maltose made of?
two glucose

what is lactose made of?

35
what is refined wheat?
they only use the endosperm. you lose a lot of the nutrients
36
what is enriched wheat?
