How Are Ketones Excreted From The Body

Ketosis, Ketones, And How It All Works

Ketosis is a process that the body does on an everyday basis, regardless of the number of carbs you eat. Your body adapts to what is put in it, processing different types of nutrients into the fuels that it needs. Proteins, fats, and carbs can all be processed for use. Eating a low carb, high fat diet just ramps up this process, which is a normal and safe chemical reaction. When you eat carbohydrate based foods or excess amounts of protein, your body will break this down into sugar – known as glucose. Why? Glucose is needed in the creation of ATP (an energy molecule), which is a fuel that is needed for the daily activities and maintenance inside our bodies. If you’ve ever used our keto calculator to determine your caloric needs, you will see that your body uses up quite a lot of calories. It’s true, our bodies use up much of the nutrients we intake just to maintain itself on a daily basis. If you eat enough food, there will likely be an excess of glucose that your body doesn’t need. There are two main things that happen to excess glucose if your body doesn’t need it: Glycogenesis. Excess glucose will be converted to glycogen and stored in your liver and muscles.

    Which of the following are likely fates of acetone in the body?
    I. Excretion in the urine
    II. Conversion back to acetoacetate
    III. Involvement in the anabolism of amino acids
    I only (Correct answer)
    I and II only
    II and III only
    I, II, and III
    "A is correct. This question is asking us to determine from the passage the likely fate of acetone. The passage mentions that acetone has no metabolic utility. Thus choices II and III are incorrect. Acetone is simply excreted in the urine.
    B, C, D: All of these choices include either II or III, which incorrectly describle metabolic uses for acetone in the body."
    I was under the impression that ketone bodies enter circulation and can be taken up by other cells and converted back to acetyl-CoA. I will admit that the passage implied that acetone had no metabolic use, and I should have answered the question off the passage information and not my background information. But I was wondering what y'all think.
    Thanks!

    This might be useful also. Showing the one way conversion of acetone. I am just a little confused because I thought ketone bodies HAD metabolic use

    Welp, I just did some googling and found the answer. The only two ketone bodies are beta-hydroxybutyrate and acetoacetate, while acetone is just a waste product. "The product of the decarboxylation reaction, acetone, is a volatile waste product, and is largely excreted via the lungs."
    Hopefully this can help someone in the future with a similar problem.
    Cheers
