Sucrose
Sucrose is the white table sugar you use every day, made from sugarcane or beets.
Think of it this way
Sucrose is like two small blocks snapped together inside a jar. One block is glucose and the other is fructose. Together they form one unit, table sugar. When you drop the pair into water, the blocks split apart and dissolve.
Explaining sucrose by grade level
Table sugar is called sucrose. Yeast is a tiny living thing that eats sugar. When you mix yeast with sugar and warm water, it makes gas. That gas is why bread dough puffs up.
