How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it acts on

  1. Acetate infusion increased muscle acetyl-CoA, citrate and acetylcarnitine, and resting active-form pyruvate dehydrogenase declined during 20 minutes of acetate infusion from 0.37 to 0.16 mmol per minute per kg wet weight, coinciding with an elevation in the acetyl-CoA to free CoA ratio from 0.28 to 0.73, whereas after the bicarbonate control infusion resting activity was similar to that before acetate.

Where it participates (unsigned role)

  1. During exercise acetyl-CoA, citrate and the acetyl-CoA to free CoA ratio were further elevated and the differences present at rest were resolved, with active-form pyruvate dehydrogenase increasing to the same extent with acetate and with the control infusion, so that during exercise its regulation appeared independent of variations in the acetyl-CoA to free CoA ratio and acetate infusion was not effective in perturbing the glucose-fatty acid cycle.
