CHAPTER I INTRODUCTION A lot of people have been getting into the weight-loss bandwagon. Nowadays there are numerous supplements and drinks that promise significant weight loss after a certain amount of time following regular consumption. One famous chemical currently advertised is L-carnitine. The substance is water soluble which oxidizes and transports long chain fatty acids into the mitochondrion (Dokmeci et al.‚ 2005; Gulcin‚ 2006)‚ transeterifies and acetyl-CoA‚ oxidizes branched chain
