L-Tetrahydrofolic Acid Chemische Eigenschaften,Einsatz,Produktion Methoden

• Chemische Eigenschaften

  Light Tan Solid

• Verwenden

  Tetrahydrofolic acid has been used to determine the inhibitory effect of tetrahydrofolate on polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs). A recent use of tetrahydrofolate (THF) is for studying the activation of riboswitches.

• Verwenden

  L-Tetrahydrofolic Acid is a folic acid derivative and coenzyme involved in the metabolism of amino and nucleic acids. We have observed that this material decomposes steadily over time. Use immediately upon receipt.

• Verwenden

  Asa folic acid derivative and coenzyme, L-Tetrahydrofolic Acid can be involved in the metabolism of amino and nucleic acids.

• Definition

  ChEBI: A derivative of folic acid in which the pteridine ring is fully reduced; it is the parent compound of a variety of coenzymes that serve as carriers of one-carbon groups in metabolic reactions.

• Flammability and Explosibility

  Not classified

• Biochem/physiol Actions

  Tetrahydrofolic acid is the parent molecule of the folate derivatives that donate one-carbon units to amino acids, nucleic acids, and lipids. Tetrahydrofolate metabolites participate in the synthesis of purine and pyrimidine and in synthesis and conversion of amino acids

• läuterung methode

  Very high quality material is now available commercially, and it should be a white powder. It can be dried over P2O5 in a vacuum desiccator and stored in weighed aliquots in sealed ampoules. It is stable at room temperature in sealed ampoules for many months and for much more extended periods at -10o. When moist, it is extremely sensitive to air whereby it oxidises to the yellow 7,8-dihydro derivative. In solution it turns yellow in colour as it oxidises, and then particularly in the presence of acids it turns dark reddish brown in colour. Hence aqueous solutions should be frozen immediately when not in use. It is always advisable to add 2-mercaptoethanol (if it does not interfere with the procedure for which it is used) which stabilises it by depleting the solution of O2. The sulfate salt is more stable but is much less soluble. The best way to prepare standard solutions of this acid is to dissolve it in the desired buffer and estimate the concentration by UV absorption in pH 7 buffer at 297nm ( 22,000 M-1cm-1). If a sample is suspect, it is not advisable to purify it because it is likely to deteriorate further as “dry box” conditions are necessary. Either a new sample is purchased or one is freshly prepared from folic acid. It has the above pKa values. [Hafeti et al.
