Here we show isolated human platelets can be used as an accessible ex vivo model to study metabolic adaptations in response to the complex I inhibitor rotenone. This approach employs isotopic tracing and relative quantification by liquid chromatography-mass spectrometry and can be applied to a variety of study designs.

The Citric Acid Cycle
0 Views •
2019
The citric acid cycle, also known as the Krebs cycle or TCA cycle, consists of several energy-generating reactions that yield one ATP molecule, three NADH molecules, one FADH2 molecule, and two CO2 molecules. Acetyl CoA is the point-of-entry into the citric acid cycle, which occurs in the inner membrane (i.e., matrix) of mitochondria in eukaryotic cells or the cytoplasm of prokaryotic cells. Prior to the citric acid cycle, pyruvate oxidation produced two acetyl CoA molecules per glucose...

Adenovirus particles are engineered to contain either the unnatural amino acid analogue azidohomoalanine or the azido sugar O-GlcNAz. The azide group of each is chemoselectively ligated via "click" chemistry reactions as a means of viral surface modification.

Pyruvate Oxidation

After glycolysis, the charged pyruvate molecules enter the mitochondria via active transport and undergo three enzymatic reactions. These reactions ensure that pyruvate can enter the next metabolic pathway so that energy stored in the pyruvate molecules can be harnessed by the cells. First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

13C-isotope labeling is a useful technique for determining the cell central metabolism for various types of microorganisms. After cells have been cultured with a specific labeled substrate, GC-MS measurement can reveal functional metabolic pathways based on unique labeling patterns in proteinogenic amino acids.
FAQs
Its thioester bond is reactive, while the neighboring carbonyl groups provide additional sites for transformation. Together, these features allow acetoacetyl-CoA to participate in condensation, cleavage, and carbon-transfer reactions. This combination makes the molecule useful as an intermediate that can connect simpler acetyl units with later metabolic products.
Thiolase forms acetoacetyl-CoA by joining two acetyl-CoA molecules through a condensation reaction. The resulting four-carbon intermediate retains the thioester functionality and adjacent carbonyl groups needed for further reactions. This step demonstrates how acetyl-CoA can be converted from a simple carbon donor into a more versatile metabolic building block.
HMG-CoA synthase combines acetoacetyl-CoA with another acetyl-CoA molecule to produce HMG-CoA. This reaction extends the carbon framework and transfers acetoacetyl-CoA into a downstream intermediate. Consequently, the compound serves as a branching point linking acetyl-CoA metabolism with pathways involving ketone-body production and cholesterol biosynthesis.
The adjacent carbonyl groups help explain why acetoacetyl-CoA can undergo several chemically distinct transformations rather than serving only one pathway. They support reactions that rearrange, cleave, or transfer carbon-containing units while the thioester connects the substrate to coenzyme A. These properties are central to its role in biochemical carbon metabolism.
Acetoacetyl-CoA is an important intermediate for studying ketone-body production and the biochemical handling of carbon during energy use. Its position among acetyl-CoA-derived compounds helps researchers examine how carbon moves through pathways associated with changing energy demands. The molecule therefore provides a chemically defined point for investigating these metabolic processes.
Acetoacetyl-CoA contributes to the study of cholesterol biosynthesis because HMG-CoA synthase uses it with acetyl-CoA to form HMG-CoA. More broadly, its reactive thioester and carbonyl groups support carbon-transfer chemistry used to construct complex carbon-containing molecules. It therefore connects fundamental reaction chemistry with larger biosynthetic pathway analysis.
