  2. Fatty acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_metabolism

    The energy yield from a gram of fatty acids is approximately 9 kcal (37 kJ), much higher than the 4 kcal (17 kJ) for carbohydrates. Since the hydrocarbon portion of fatty acids is hydrophobic , these molecules can be stored in a relatively anhydrous (water-free) environment.

  3. Calcium propanoate - Wikipedia

    en.wikipedia.org/wiki/Calcium_propanoate

    Propionates prevent microbes from producing the energy they need, like benzoates do. However, unlike benzoates, propionates do not require an acidic environment. [4] Calcium propionate is used in bakery products as a mold inhibitor, typically at 0.1–0.4% [5] (though animal feed may contain up to 1%). Mold contamination is considered a serious ...

  4. Ketonic decarboxylation - Wikipedia

    en.wikipedia.org/wiki/Ketonic_decarboxylation

    The dry distillation of calcium acetate to give acetone was reported by Charles Friedel in 1858 [3] and until World War I ketonization was the premier commercial method for its production. [ 4 ] Ketonic decarboxylation of propanoic acid over a manganese(II) oxide catalyst in a tube furnace affords 3-pentanone .

  5. Dry distillation - Wikipedia

    en.wikipedia.org/wiki/Dry_distillation

    Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). The method may involve pyrolysis or thermolysis, or it may not (for instance, a simple mixture of ice and glass could be separated without breaking any chemical bonds, but organic matter contains a greater diversity of molecules, some of which are likely to break).

  6. Metabolism - Wikipedia

    en.wikipedia.org/wiki/Metabolism

    Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...

  7. Transesterification - Wikipedia

    en.wikipedia.org/wiki/Transesterification

    In the transesterification mechanism, the carbonyl carbon of the starting ester reacts to give a tetrahedral intermediate, which either reverts back to the starting material, or proceeds to the transesterified product (RCOOR 2). The various species exist in equilibrium, and the product distribution depends on the relative energies of the ...

    New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...

  9. List of food additives - Wikipedia

    en.wikipedia.org/wiki/List_of_food_additives

    Flavors are additives that give food a particular taste or smell, and may be derived from natural ingredients or created artificially. Flavor enhancers Flavor enhancers enhance a food's existing flavors. They may be extracted from natural sources (through distillation, solvent extraction, maceration, among other methods) or created artificially.
