Cells were incubated with 14 C labeled glucose in the second position. The uracil synthesized in the cell is found to have labeled carbon ( 14 C) at the 4 th and 6 th positions. The pattern for such labeling in uracil should be determined. Concept introduction: Purines are heterocyclic organic compounds. Purine is composed of two fused rings, a pyrimidine ring, and an imidazole ring. Adenine and guanine, found in nucleic acids , are the purines. Moreover, purines are water-soluble compound and are metabolized by xanthine oxidase into uric acid.
