  2. Purine metabolism - Wikipedia

    en.wikipedia.org/wiki/Purine_metabolism

    The amino acid glycine contributes all its carbon (2) and nitrogen (1) atoms, with additional nitrogen atoms from glutamine (2) and aspartic acid (1), and additional carbon atoms from formyl groups (2), which are transferred from the coenzyme tetrahydrofolate as 10-formyltetrahydrofolate, and a carbon atom from bicarbonate (1). Formyl groups ...

  3. Glycine - Wikipedia

    en.wikipedia.org/wiki/Glycine

    In the US, glycine is typically sold in two grades: United States Pharmacopeia ("USP"), and technical grade. USP grade sales account for approximately 80 to 85 percent of the U.S. market for glycine. If purity greater than the USP standard is needed, for example for intravenous injections, a more expensive pharmaceutical grade glycine can be ...

  4. Purine - Wikipedia

    en.wikipedia.org/wiki/Purine

    Purine is a heterocyclic aromatic organic compound that consists of two rings (pyrimidine and imidazole) fused together.It is water-soluble.Purine also gives its name to the wider class of molecules, purines, which include substituted purines and their tautomers.

  5. Pyridine - Wikipedia

    en.wikipedia.org/wiki/Pyridine

    Sulfonation of pyridine is even more difficult than nitration. However, pyridine-3-sulfonic acid can be obtained. However, pyridine-3-sulfonic acid can be obtained. Reaction with the SO 3 group also facilitates addition of sulfur to the nitrogen atom, especially in the presence of a mercury(II) sulfate catalyst.

  6. Glycylglycine - Wikipedia

    en.wikipedia.org/wiki/Glycylglycine

    Glycylglycine is the dipeptide of glycine, making it the simplest peptide. [1] The compound was first synthesized by Emil Fischer and Ernest Fourneau in 1901 by boiling 2,5-diketopiperazine (glycine anhydride) with hydrochloric acid. [2] Shaking with alkali [1] and other synthesis methods have been reported. [3]

  7. Glycine cleavage system - Wikipedia

    en.wikipedia.org/wiki/Glycine_cleavage_system

    The glycine cleavage system (GCS) is also known as the glycine decarboxylase complex or GDC. The system is a series of enzymes that are triggered in response to high concentrations of the amino acid glycine. [1] The same set of enzymes is sometimes referred to as glycine synthase when it runs in the reverse direction to form glycine. [2]

  8. Glycin - Wikipedia

    en.wikipedia.org/wiki/Glycin

    Glycin, or N-(4-hydroxyphenyl)glycine, is N-substituted p-aminophenol. It is a photographic developing agent used in classic black-and-white developer solutions. [2] It is not identical to, but derived from glycine, the proteinogenic amino acid. It is typically characterized as thin plates of white or silvery powder, although aged samples ...

  9. Sweetness - Wikipedia

    en.wikipedia.org/wiki/Sweetness

    The sweetness of 5% solution of glycine in water compares to a solution of 5.6% glucose or 2.6% fructose. [14] A number of plant species produce glycosides that are sweet at concentrations much lower than common sugars. The most well-known example is glycyrrhizin, the sweet component of licorice root
