L-Carnitine What it does
Biochemical functions
The primary function of carnitine in the body is to facilitate
the burning of fatty acids for metabolic energy. Fat metabolism
occurs inside the mitochondria (see CoQ10 description, paragraph
2)
via beta-oxidation. However, fatty acids cannot penetrate the
inner mitochondrial membrane, and a transport system - composed
of carnitine and at least three enzymes - is required to effect
passage. Another equally important metabolic role is the removal
of the beta-oxidation products out of the mitochondria. Although
it is a perfectly natural substance, carnitine is widely
prescribed in Italy as a medicine for use in chronic fatigue and
muscle weakness and there are many clinical trials proving this.
