Purine Metabolism; de novo synthesis and salvage pathway, 2016: Transcript

Most cells actively turnover their NAs especial RNAs This results in the release of adenosine adenine guanine and hypoxanthine These are recovered thru salvage pathways . OBJECTIVES:. Nomenclature of nucleic acids: . a. nucleosides*. . b. nucleotides. Structure . and function of . purines and pyrimidines. . Origin . of atoms in the purine . ring and in the pyrimidine ring.. nucleotides is essential for . life . processes. nucleotides . are the . activated precursors . of nucleic . acids. As such, they are necessary for the replication of the genome . an . adenine nucleotide, ATP, is . C483 Spring 2013. 1.

Nitrogenous Bases. Planar, aromatic, and heterocyclic. Derived from . purine. or . pyrimidine. Numbering of bases is “unprimed”. Nucleic Acid Bases. Purines. Pyrimidines. Sugars. Pentoses. Purines are biologically synthesized as nucleotides and in particular as ribotides, i.e. bases attached to ribose-5-phosphate. . Purines are synthesized by two types of pathways, the de novo pathways and the salvage pathways.. De Novo. Synthesis of . Purine. Nucleotides. We use for . purine. nucleotides the entire . glycine. molecule (atoms 4, 5,7), the amino nitrogen of . aspartate. (atom 1), amide nitrogen of glutamine (atoms 3, 9), components of the . Metabolism.

Catabolism of Purines and Pyrimidines. OBJECTIVES:. Nomenclature of nucleic acids: . a. nucleosides*. . b. nucleotides. Structure . and function of . purines and pyrimidines. . Origin . of atoms in the purine . ring and in the pyrimidine ring.. One of the important specialized pathways of a number of amino acids is the synthesis of purine and pyrimidine nucleotides. . These nucleotides are important for a number of reasons. Most of them, not just ATP, are the sources of energy that drive most of our reactions.. Dr. Anissa Atif Mirza. Synopsis.
