Mitochondial function is important for triglyceride reduction

Mitochondrial function is a contributing, but not necessarily essential factor to lower the levels of triglycerides in plasma, according to Carine Lindquist‘s PhD thesis.


  1. 1-triple TTA reduces triglyceride levels in plasma as a result of increased hepatic mitochondrial oxidation.
  2. 1-triple TTA reduces triglyceride levels in plasma even when levels of L-carnitine are low.
  3. 1-triple TTA probably influences triglyceride clearance and biosynthesis.

(1) Rats fed for three weeks with 2-(tridec-12-yn-1-ylthio)acetic acid (1-triple TTA) had a five-fold increase of hepatic mitochondrial oxidation of fatty acids. Triglyceride levels in both plasma and liver decreased substantially, probably as a consequence of downregulated APOC-III and upregulated LPL and the VLDL receptor.

(2) L-carnitine is important for the catabolism of long-chain fatty acids in the mitochondria, but Lindquists second study shows that 1-triple TTA increases mitochondrial fatty acid oxidation even when L-carnitine levels are low. The results indicate that 1-triple TTA also influences changes in plasma clearance and reduced biosynthesis of triglycerides.
