L-Carnitine and Lipoproteins

The oxidation of fatty acids occurs in the mitochondria, but fatty acids are unable to cross the inner mitochondrial membrane unaided. L-carnitine is involved in the shuttle system that allows fatty acids to cross this inner membrane which allows β-oxidation … Continue reading

Extra-Virgin Olive Oil

Olive oil contains virtually no alpha linolenic acid (ALA) and only small quantities of linoleic acid (LA), but is instead composed of mainly monounsaturated oil. Despite this, research suggests that olive oil has a preventative effect against cardiovascular disease. Extra-virgin … Continue reading

Decreasing Arachidonic Acid Levels

Arachidonic acid is a polyunsaturated fatty acid (PUFA) (AA, 20: 4 (n-6)) that is enzymatically converted to a number of pro-inflammatory eicosanoids. In particular, AA is converted via COX (cyclooxygenase) enzymes to the series 2 prostanoids (prostaglandins and thromboxanes) and … Continue reading
