TECHNOLOGY FOCUS - BIOLOGY - Preferred Enzyme: The energy generator is enzyme concerned in (beta)-oxidation, acyl-CoA synthetase, acyl-CoA dehydrogenase, enoyl CoA hydratase, 3-hydroxy acyl-CoA dehydrogenase, (beta)-keto thiolase, acetyl-CoA acyltransferase, propionyl-CoA carboxylase, methyl malonyl-CoA epimerase, enoyl-CoA isomerase, 2,4-dienoyl-CoA reductase, fatty-acid acyl-CoA dehydrogenase, methyl malonyl-CoA mutase, citrate synthase, aconitic-acid hydratase, iso-citric acid hydrogenase, hexokinase, glucokinase, phosphoglucose isomerase, phospho fructokinase, aldolase, triose phosphate isomerase, glyceraldehyde-3-phosphoric acid dehydrogenase, phosphoglyceride kinase, phospho glyceromutase, enolase, pyruvate kinase, 2-oxo glutaric acid dehydrogenase, succinyl-CoA synthetase, succinate dehydrogenase, fumaric acid dehydrogenase, enzyme concerned in tricarboxylic acid cycle, malate dehydrogenase, enzyme concerned in (alpha)-oxidation, enzyme concerned in (omega)-oxidation monooxygenase and cytochrome P-450, lipase concerned in electron transport system, NADH dehydrogenase, nicotinamide adenine dinucleotide (NAD), nicotinamide adenine dinucleotide phosphate (NADP), coenzyme A, flavin adenine dinucleotide (FAD), guanosine 5'-diphosphate (GDP) and adenosine triphosphate (ATP).    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Apparatus: The reactor is removable from the surface electrode and contains nano electrode (15) electrically connected to the surface electrode. The energy generator consists of another electrode electrically connected to living body surface. Pulse voltage is applied to the living body surface using the storage battery as power source. The generator further comprises ultrasonic generator, electric power source and control apparatus. The exudation of saccharide, fats and/or fatty acid to the living body surface is promoted by generating ultrasonic wave using the storage battery. The electric power source supplies electric power for initial stage operation until the storage battery is charged. The control apparatus controls the decomposition amount. The electrical energy produced by enzymatic decomposition is monitored. The electric equipment is embedded in the living body.
