چکیده

Opposing evidence exists for the source of hydrogen ions (H+) during ketoacidosis. Organic and computational chemistry using dissociation constants alpha equations all pertinent ionizable metabolites were used to (1) document atomic changes in chemical reactions ketogenesis ketolysis (2) identify sources quantify added fractional (~) H+ exchange (~H+e). All computations performed pH conditions spanning from 6.0 7.6. Summation ~H+e given substrates products each reaction resulted net pathway coefficients, where negative revealed ~H+ release positive uptake. Results that liver (pH = 7.0), ending acetoacetate (AcAc), β-hydroxybutyrate (β-HB), acetone −0.9990, 0.0026, 0.0000, respectively. During ketogenesis, was only evident HMG CoA production, which is caused by hydrolysis not dissociation. Nevertheless, there a though this diminishes with greater proportionality production. For muscle 7.1) brain 7.2), coefficients β-HB AcAc oxidation −0.9649 0.0363 (muscle), −0.9719 0.0291 (brain), The larger values result covalent oxidation–reduction. combined ketolysis, would be metabolic condition vivo, coefficient depends once again on final ketone body product. production liver, transference blood, ratio 0.6:0.2:0.2 β-HB:AcAc:acetone, blood transfer, total (ketosis) equate −0.1983, −0.0003, −0.2872, −0.4858, traditional theory bodies being acids causing systemic acidosis incorrect. yield differ depending though, general, small ketosis. Products formed (HMG-CoA, acetoacetate, β-hydroxybutyrate) are created as negatively charged bases, acids, body, acetone, does have pH-dependent groups. Proton or uptake predominantly modification, acid dissociation/association. Ketosis (ketogenesis ketolysis) results release. extent dependent between β-hydroxybutyrate, acetone.

Computational chemistry

Computational chemistry has come of age. With significant strides in computer hardware and software over the last few decades, computational chemistry has achieved full partnership with theory and experiment as a tool for understanding and predicting the behavior of a broad range of chemical, physical, and biological phenomena. The Nobel Prize award to John Pople and Walter Kohn in 1998 highlig...

A computational chemistry investigation of the intermolecular interaction between ozone and isothiocyanic acid (HNCS)

The binding energy and geometrical structure of all the possible dimeric systems of isothiocyanic acid (HNCS) with ozone have been investigated in the gas phase, theoretically. Six minima located on the singlet potential energy surface of the HNCS–ozone system at the MP2 level with binding energies (corrected with ZPE and BSSE) in the range 492.29–531.40 kcal/mol. All intermolecular interaction...

Figure 1. Process chart of feedback-driven hit generation. A random selection of molecules from the database initiates a cycle containing an assay, a learning and prediction step, and a selection of a new subset from the database. In case of an experimental in vitro assay, the selected compounds have to be synthesised. An in silico screening process avoids the rate-limiting step of chemical syn...
