Parcourir une grande sélection de produits et pour en savoir plus sur Thymine, 99 %, Acros Organics™: Construction des éléments organiques Produits chimiques . Thymine deoxyribosi de. The phosphate of the nucleotides forms the backbone of the DNA double helix, while the hydrogen bonds between the bases run through the center of the helix and stabilize the molecule. Grain processing removes much of the thiamine content, so in many countries cereals and flours are enriched with thiamine. Thymine combines with the sugar deoxyribose to form thymidine. As the name suggests, thymine may be derived by methylation of uracil at the 5th carbon. Thymine is found in both prokaryotic and eukaryotic cells, but it does not occur in RNA viruses. Thymidine may be phosphorylated with up to three phosphoric acid groups to form deoxythymidine monophosphate (dDMP), deoxythymidine diphosphate (dTDP), and deoxythymidine triphosphate (dTTP). CAS Number: 65-71-4 . It is also known as 5-methyluracil or by the abbreviations T or Thy. Sign In It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2). A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. It forms the nucleotide, thymidine.
