Here we describe a method to directly visualize microregional tissue hypoxia in the mouse cortex in vivo. It is based on concurrent two-photon imaging of nicotinamide adenine dinucleotide (NADH) and the cortical microcirculation. This method is useful for high resolution analysis of tissue oxygen supply.

The energy released from the breakdown of the chemical bonds within nutrients can be stored either through the reduction of electron carriers or in the bonds of adenosine triphosphate (ATP). In living systems, a small class of compounds functions as mobile electron carriers, molecules that bind to and shuttle high-energy electrons between compounds in pathways. The principal electron carriers that will be considered originate from the B vitamin group and are derivatives of nucleotides; they are...

There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a different solvent. A simple way to predict which substances dissolve in which solvent is the phrase "like dissolves like". This means that polar substances, such as salt and sugar, dissolve in a polar substance like water. In contrast, non-polar substances are more soluble in non-polar solvents such as carbon tetrachloride. This selective solubility...

Standard Enthalpy of Formation

Enthalpy changes are typically tabulated for reactions in which both the reactants and products are at the same conditions. A standard state is a commonly accepted set of conditions used as a reference point for the determination of properties under other different conditions. For chemists, the IUPAC standard state refers to materials under a pressure of 1 bar and solutions at 1 M and does not specify a temperature. Many thermochemical tables list values with a standard state of 1 atm. Because...

NADH formation is driven by oxidation reactions in which metabolic substrates lose hydrogen atoms or electrons. Enzymes mediate that transfer, directing the removed reducing power to NAD+, which becomes NADH. This process links substrate oxidation to electron storage in a mobile coenzyme. The resulting NADH can later deliver those electrons to energy-producing pathways.
Each pathway contributes because it contains oxidation reactions that can transfer hydrogen atoms or electrons from metabolic substrates to NAD+. Glycolysis, pyruvate oxidation, and the citric acid cycle therefore represent distinct stages at which reducing power can be captured as NADH. Considering them together connects substrate breakdown with downstream electron delivery and cellular energy production.
NADH formation supports ATP production indirectly rather than supplying ATP itself. Once NADH delivers its high-energy electrons to the electron transport chain, electron transfer supports creation of a proton gradient. Oxidative phosphorylation then uses that gradient for ATP production. This sequence links oxidation reactions with cellular energy output through electron transfer and gradient formation.
NAD+ and NADH represent two functional states of the same coenzyme. NAD+ accepts hydrogen atoms or electrons during oxidation, whereas NADH carries the captured high-energy electrons onward to the electron transport chain. This conversion allows the coenzyme to connect reactions that extract reducing power from substrates with processes that support ATP production.
Researchers can investigate NADH formation by measuring it during relevant metabolic activity or by manipulating the process and observing resulting changes. The analysis can focus on glycolysis, pyruvate oxidation, the citric acid cycle, or mitochondrial function. These approaches help relate electron capture to redox balance and energy production rather than treating NADH as an isolated measurement.
Measurements of NADH formation can illuminate how cells produce energy, how mitochondria function, and how redox balance is maintained. Because the process occurs across major metabolic pathways, researchers can use it to examine metabolism in health and disease. Results become more informative when formation is considered alongside electron transport and ATP production.
