If you let a piece of candy melt in your mouth - BUT NEVER SWALLOWED - would the sugar be absorbed through the walls of your mouth?
I’m assuming complex sugar
No it’s absorbed in your mouth , but it’s broken Down into maltose in your mouth due to action of salivary amylase
it’s mainly absorbed in small intestine via active transport or simple diffusion if found in small amount.
There are evidences that it’s absorbed in stomach. But that depends on type of sugar
