    What's the differences between the sugars?

    How are sucrose, fructose, lactose, and glucose the same and different? And are there other sugars?

    I always get confused by all the sugars.

    I'm a co-worker of Questor's and I had asked him this question. We thought we'd stop speculating and just post it!

    The reason I asked is because I love bananas, but I've seem some people state their dislike for the nutritional value within these boards, but I didn't know why.

    all carbohydrates are made of sugars

    the difference between all the sugars is they each have a different molecular configuration.

    But is there a difference in the amount of energy needed to break down the different sugars?

    this is a really good one:

    Sugars are called "saccharides". A "monosaccharide" has a single sugar molecule. There are three different types of monosacharides: glucose (aka dextrose), fructose, and galactose. These all have similar but different molecular structures.
    Combining two monosaccharides forms a disaccharide:
    glucose + glucose = maltose
    glucose + galactose = lactose
    glucose + fructose = sucrose

    I hope that helps....I was reaching way back into grade 11 biology.

    Different sugars are processed by the body different. Glucose can be converted to glycogen and stored in muscle. Fructose cannot, and is metabolised in the liver.

    So what happens to fructose? Is fructose worse than the others or better than the others or just different because it's processed by the liver.

    I looked over those links, I'm sorry I don't have much of a head for that stuff.

    Wow!

    Fantastic article! Exactly what I was looking for...

    So bananas aren't going to ruin my cut, but I need to balance them with glucose intake.

    That's what I got from that (and also that a few pieces of fruit arne't going to ruin anything really anyway).

    I like my fruits first thing in the morning. Post WO shake is always whey/dex. At bedtime I may throw in some fruit with my CC/PB meal, depending on if I have cals/carbs allotment left.
