  2. Glyoxylate and dicarboxylate metabolism - Wikipedia

    en.wikipedia.org/wiki/Glyoxylate_and_dicarboxyl...

    Glyoxylate and dicarboxylate metabolism describes a variety of reactions involving glyoxylate or dicarboxylates.Glyoxylate is the conjugate base of glyoxylic acid, and within a buffered environment of known pH such as the cell cytoplasm these terms can be used almost interchangeably, as the gain or loss of a hydrogen ion is all that distinguishes them, and this can occur in the aqueous ...

  3. Glyoxylate cycle - Wikipedia

    en.wikipedia.org/wiki/Glyoxylate_cycle

    Fatty acids from lipids are commonly used as an energy source by vertebrates as fatty acids are degraded through beta oxidation into acetate molecules. This acetate, bound to the active thiol group of coenzyme A, enters the citric acid cycle (TCA cycle) where it is fully oxidized to carbon dioxide. This pathway thus allows cells to obtain ...

  4. Glyoxylate reductase - Wikipedia

    en.wikipedia.org/wiki/Glyoxylate_reductase

    The studies have shown that these genes are in fact present in animals, but the redistribution of the genes suggest that either that (1) these genes encode other enzymes that take part in the glyoxylate cycle, but are not orthologous to the known enzymes in the cycle, or (2) animals have developed a new function for these enzymes that have yet ...

  5. Hopkins–Cole reaction - Wikipedia

    en.wikipedia.org/wiki/Hopkins–Cole_reaction

    The Hopkins-Cole reaction, also known as the glyoxylic acid reaction, is a chemical test used for detecting the presence of tryptophan in proteins. [1] A protein solution is mixed with Hopkins Cole reagent, which consists of glyoxylic acid. Concentrated sulfuric acid is slowly added to form two layers. A purple ring appears between the two ...

  6. Adamkiewicz reaction - Wikipedia

    en.wikipedia.org/wiki/Adamkiewicz_reaction

    The reaction relies on the interaction between glyoxylic acid and the indole ring of the amino acid tryptophan, a structural feature found in most proteins. When proteins are exposed to concentrated sulfuric acid and glyoxylic acid, the indole group undergoes a reaction that produces a highly colored compound.

  7. Glycine dehydrogenase - Wikipedia

    en.wikipedia.org/wiki/Glycine_dehydrogenase

    In enzymology, a glycine dehydrogenase (EC 1.4.1.10) is an enzyme that catalyzes the chemical reaction glycine + H 2 O + NAD + ⇌ {\displaystyle \rightleftharpoons } glyoxylate + NH 3 + NADH + H + The 3 substrates of this enzyme are glycine , H 2 O , and NAD + , whereas its 4 products are glyoxylate , NH 3 , NADH , and H + .

  8. Glyoxylic acid - Wikipedia

    en.wikipedia.org/wiki/Glyoxylic_acid

    Glyoxylic acid is one of several ketone- and aldehyde-containing carboxylic acids that together are abundant in secondary organic aerosols. In the presence of water and sunlight, glyoxylic acid can undergo photochemical oxidation. Several different reaction pathways can ensue, leading to various other carboxylic acid and aldehyde products. [31]

  9. Glyoxylate oxidase - Wikipedia

    en.wikipedia.org/wiki/Glyoxylate_oxidase

    The 3 substrates of this enzyme are glyoxylate, H 2 O, and O 2, whereas its two products are oxalate and H 2 O 2. This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with oxygen as acceptor. The systematic name of this enzyme class is glyoxylate:oxygen oxidoreductase.
