What Is DNA?- Meaning, DNA Types, Structure and Functions
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. They are the most widely occurring nitrogen … See more Purines are found in high concentration in meat and meat products, especially internal organs such as liver and kidney. In general, plant-based diets are low in purines. High-purine plants and algae include some … See more Purines and pyrimidines make up the two groups of nitrogenous bases, including the two groups of nucleotide bases. The purine bases are guanine (G) and adenine (A) which form corresponding nucleosides-deoxyribonucleosides (deoxyguanosine See more There are many naturally occurring purines. They include the nucleobases adenine (2) and guanine (3). In DNA, these bases form hydrogen bonds with their complementary pyrimidines, thymine and cytosine, respectively. This is called complementary … See more Many organisms have metabolic pathways to synthesize and break down purines. Purines are biologically synthesized as nucleosides (bases … See more Purine is both a very weak acid (pKa 8.93) and an even weaker base (pKa 2.39). If dissolved in pure water, the pH is half way between these two pKa values. Purine is aromatic, having four tautomers each with a hydrogen bonded to a different one of the four … See more Aside from the crucial roles of purines (adenine and guanine) in DNA and RNA, purines are also significant components in a number of other important biomolecules, such as See more The word purine (pure urine) was coined by the German chemist Emil Fischer in 1884. He synthesized it for the first time in 1898. The starting material for the reaction sequence was See more WebMar 1, 2024 · Synthesis of [15 N4 ] purine labeled cytokinine glycosides derived from zeatins and topolins containing a 9-β-d, 7-β-d-glucopyranosyl, or 9-β-d-ribofuranosyl group is described. These N6 -substituted adenine derivatives are intended as internal analytic standards for phytohormone analysis.
