    Hi,
    I've just started 6th form at my local college and I chose A-Level Biology (why I'm not sure), but I am stuck on this one question which I don't understand at all and my teacher is the most unapproachable guy ever.

    "A triglyceride does not contain sucrose or bond x (which I think I identified as a glycosidic bond). Give one other way in which the structure of a triglyceride is different to a olestra."

    It's from a past paper which I can't find the mark scheme to and I literally have no clue what an olestra is.

    So if you could help, that would be great thanks!

    If you're not expected to know what an olestra is (e.g. it's not in your spec) the answer will be somewhere on the paper. If they've given you a diagram of the structure of an olestra then you must use your knowledge of triglycerides to identify another difference.

    Thanks very much for replying, I just sat and stared at it for ages and it clicked I think! It was something about what it contained!
    Thanks again!
