Iodoacetate is an irreversible inhibitor of all cysteine peptidases, with the mechanism of inhibition occurring from alkylation of the catalytic cysteine residue (see schematic). In comparison with its amide derivative, iodoacetamide, iodoacetate reacts substantially slower. This observation appears contradictory to standard chemical reactivity ...
The ATP/ADP ratio and proton gradients generated by these processes play a central role in this coupling. Experimental evidence shows that inhibitors targeting glycolysis, such as 2-deoxyglucose or iodoacetate, stop both NADH and mitochondrial membrane potential oscillations, highlighting the enzymatic regulation within the glycolytic pathway.

Iodoacetamide is an irreversible inhibitor of all cysteine peptidases, with the mechanism of inhibition occurring from alkylation of the catalytic cysteine residue (see schematic). In comparison with its acid derivative, iodoacetate, iodoacetamide reacts substantially faster.
Therefore, glycolysis proceeds, but the ATP molecule that would be generated from 1,3-bisphosphoglycerate is lost – arsenate is an uncoupler of glycolysis, explaining its toxicity. [ 22 ] [ 23 ] As with other arsenic compounds, arsenate binds to lipoic acid , inhibiting the conversion of pyruvate into acetyl-CoA , blocking the Krebs cycle and ...
d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...

The first reaction is the oxidation of glyceraldehyde 3-phosphate (G3P) at the position-1 (in the diagram it is shown as the 4th carbon from glycolysis), in which an aldehyde is converted into a carboxylic acid (ΔG°'=-50 kJ/mol (−12kcal/mol)) and NAD+ is simultaneously reduced endergonically to NADH.
The FDA has banned red dye No. 3, as the synthetic additive is known to cause cancer. Nutritionists Ilana Muhlstein and Robin DeCicco discuss what this means for American health.
