How does bread turning into sugar work? Why aren’t carbs considered sugar?

Question

Title says it all

In: Biology

Answer 1

Your question is more a matter of language than chemistry:

_All_ carbohydrates _are_ sugars: sucrose, glucose, fructose, lactose, galactose, dextrose — you name em. They all belong in the saccharine category, and saccharine come from the Greek word for sugar: zachari.

However, when people talk about _sugar_, they almost exclusively refer to table sugar, which is a mix of fructose and glucose.

So to answer your two questions: bread doesn’t turn into sugar, it _is_ sugar — just not the same sugar as what you put into your coffee; and carbs _are_ sugars, but people simply refer to a particular few of them when they say that word.
