It is recommended you use lcarnitine as a positive control promotes betaoxidation, and etomoxir as a negative control inhibits betaoxidation. In biochemistry and metabolism, betaoxidation is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetylcoa, which enters the citric acid cycle, and nadh and fadh 2, which are coenzymes used in the electron transport chain. Pa is the most common saturated fatty acid accounting for 2030% of total fatty. Thus, the effects of coa and palmitate alone and in combine tion on succinic. Fatty acid metabolism other fatty acid oxidation 1. Oxidation is primarily involved in the degradation of fatty acids. Potential negative effects of excess lipid availability may combine with. For example, the 16carbon fatty acid palmitic acid palmitate at ph 7. In the mitochondria, loss of electrons from complexes i and iii of the electron transport chain etc can combine with. For etomoxir, it is recommended you preincubate your cells with 110um for an hour, and.
