Glucose, fructose, lactose -- most of us know about these sugars and what they are found in. But galactose is very much a foreign term for most people. I remember hearing it in science class but I had forgotten all about since it's not something I hear often. But other sugars like fructose (fruit sugar) and lactose (milk sugar), I hear about all the time.
It sounds like galactose is a great sugar. It's efficient and apparently useful too. Why can't scientists find a way to make it dissolve in liquids? I bet galactose would quickly replace other sweeteners on the market if that happened.
