Nucleic Acids: entrega.uribe_4
1 Nomenclature
1.1 According to the attached molecules
1.1.1 Sugar+Nitrogenous base = Nucleoside (also known as aglicone) Nucleoside + phosphate = Nucleotide Nucleotide 1 + ... + Nucleotide n = Nucleic Acid
1.2 According to the ammount of phosphate gropus
1.2.1 monophosphate
1.2.2 Diphosphate
1.2.3 Triphosphate
2 Main types
2.1 ARN: Ribonucleic acid
2.1.1 Bases A , G, U and C
2.1.2 Sugar Desoxyrribose
2.1.3 Functions Genetic information intracell messenger: RNAm Genetic information transport: RNAt
2.2 ADN: Desoxyribonucleic acid
2.2.1 Bases A,T,G and C
2.2.2 Functions Genetic information storage
2.2.3 Sugar Ribose
2.2.4 Structure Double helicoidal strand Phosphoric acid (outside); nitrogenous bases (inside)
3 Composed by nucleotides
3.1 Structure
3.1.1 Are composed by 5 carbon sugar (β-D-ribofuranose) Desoxyrribose Ribose Nitrogenous base Pirimidines Cytosine (C) Uracil (U) Thymine (T) Purines Adenine (A) Guanine (G) Phosphoric acid
3.1.2 General aspects Covalent N-glycosidic bond between C-1'(anomeric carbon of the sugar) And N-1 of the pirimidinic ring N-9 of the purinic ring 1 or more phosphate groups esterified to the hydroxyl group of the sugar or another -OH grups present in phosphoric acid Linear arrangement Cyclic arrangement
3.2 Physicochemical properties
3.2.1 Ionic Acidic behaviour many pKa's Ionic dissotiation equilibrium Can be feasibly crystalized
3.2.2 Complex formation Phosphate groups have affinity towards divalent cations Are involved into phosphate transference enzymatic reactions
3.2.3 UV light absrobance Allows to identify then by using spectrophotometric methods
