Toward Dollar Devices for Measuring Metabolic Biochemistry

Life as we know it involves four general classes of low molecular bio­ chemicals: carbohydrates, amino acids, lipids, and nucleotides. The synthesis and degradation of those chemicals, the anabolic and cata­ bolic processes that are the basis of all biochemistry, are dependent on the two key molecules of energetics: ATP (adenosine triphosphate) and NADH (nicotinamide adenine dinucleotide). These molecules are the fundamental basis of bioenergetics and, therefore, of all life as we know it, ranging from the most primitive, simple bacteria to the most recent primates [1,2].
