Prominent veins can appear anywhere due to inflammation...hands, feet and temporal region...anywhere, in fact
Through a system involving the enzymes carnitine palmitoyltransferase I (CPT-I) and carnitine palmitoyltransferase II (CPT-II), L-carnitine binds to fatty acid molecules, transports them into the mitochondrial matrix, and releases them for beta-oxidation, the process that breaks fatty acids down into acetyl-CoA units for energy production in the citric acid cycle
They also can reduce chronic inflammation, which disrupts sleep and impedes recovery
In older children or adults it may be considered if there are clinical symptoms suggestive of carnitine deficiency (hypotonia, lethargy), a significant decrease in the serum free carnitine levels, an impairment in hepatic function tests, or hyperammonaemia, even in the absence of VHE
