  2. Pasteur effect - Wikipedia

    en.wikipedia.org/wiki/Pasteur_effect

    Despite the bactericidal effects of ethanol, acidifying effects of fermentation, and low oxygen conditions of industrial alcohol production, bacteria that undergo lactic acid fermentation can contaminate such facilities because lactic acid has a low pKa of 3.86 to avoid decoupling the pH membrane gradient that supports regulated transport.

  3. Carbohydrate catabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_catabolism

    The production of ATP is achieved through the oxidation of glucose molecules. In oxidation, the electrons are stripped from a glucose molecule to reduce NAD+ and FAD. NAD+ and FAD possess a high energy potential to drive the production of ATP in the electron transport chain. ATP production occurs in the mitochondria of the cell.

  4. Monosaccharide - Wikipedia

    en.wikipedia.org/wiki/Monosaccharide

    These specific monosaccharide names have conventional three-letter abbreviations, like "Glu" for glucose and "Thr" for threose. Generally, a monosaccharide with n asymmetrical carbons has 2 n stereoisomers. The number of open chain stereoisomers for an aldose monosaccharide is larger by one than that of a ketose monosaccharide of the same length.

  5. Auto-brewery syndrome - Wikipedia

    en.wikipedia.org/wiki/Auto-brewery_syndrome

    A case of urinary fermentation of carbohydrates by endogenous microorganisms leading to urinary ethanol has been reported. This single reported case is associated with diabetes due to the presence of sugar in the urine for the yeast to ferment. The person did not develop symptoms of intoxication, but did test positive in the urine for alcohol.

  6. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    After resorption in the gut, the monosaccharides are transported, through the portal vein, to the liver, where all non-glucose monosacharids (fructose, galactose) are transformed into glucose as well. [4] Glucose (blood sugar) is distributed to cells in the tissues, where it is broken down via cellular respiration, or stored as glycogen.

  7. Glucose - Wikipedia

    en.wikipedia.org/wiki/Glucose

    The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form—due to the presence of alcohol and aldehyde or ketone functional groups, the form having the straight chain can easily convert into a chair-like hemiacetal ring structure commonly found in carbohydrates. [53]

  8. Sugars in wine - Wikipedia

    en.wikipedia.org/wiki/Sugars_in_wine

    Sucrose is a disaccharide, a molecule composed of the two monosaccharides glucose, and fructose. Invertase is the enzyme cleaves the glycosidic linkage between the glucose and fructose molecules. In most wines, there will be very little sucrose, since it is not a natural constituent of grapes and sucrose added for the purpose of chaptalisation ...

  9. Fructolysis - Wikipedia

    en.wikipedia.org/wiki/Fructolysis

    Fructose is a dietary monosaccharide present naturally in fruits and vegetables, either as free fructose or as part of the disaccharide sucrose, and as its polymer inulin. It is also present in the form of refined sugars including granulated sugars (white crystalline table sugar, brown sugar , confectioner's sugar , and turbinado sugar ...
