    Increase in blood fatty acid levels in unstressed conditions?

    Advertisements



    Here is an extra credit question from my undergrad physiology course which I am trying to answer, but cannot come up with a logical answer.
    "A resting, unstressed person has elevated plasma levels of free fatty acids, glycerol, amino acids, and ketones. Give two possible explanations for these findings, and describe what further lab tests might be used to distinguish between these two conditions."

    I was thinking about anorexia being one of the possibilities, but then isn't that an stressed condition itself? Also I was thinking about over-consumption of lipids, but why would that cause an increase in the ketone bodies as well? The question about the lab tests is also throwing me off, because I don't even know how these two conditions can be distinguished. I would really appreciate your insightful replies.
    Thank you.

    how about if he is on glucorcorticoids? elevated FAs, amino acids,gycerol all arise from increased catabolism propably going on to gluconeogenesis.also DM but i m thinking the DM guy will ve to be stressed.

    The person is a trained athlete with high activity of lipolysis resulting in elevated levels of glycerol and FFA. And the elevated levels of AA is due amino acid (alanine) mobilization to the liver for gluconeogenesis. Stress is subjective.
