Enzyme

• Nucleic Acids


  Large, chain-like macromolecules containing phosphoric acid, sugar, and nitrogenous base
• Components of Nucleic Acids


  • Phosphoric acid
  • Sugar
  • Nitrogenous base
• Sugar


  1. carbon sugar called a pentose
• Types of Pentose


  • Ribose: RNA
  • Deoxyribose: DNA
• Phosphoric acid


  Composed of one or more phosphate groups (PO4)
• Nitrogenous bases


  • Purine
  • Pyrimidine
• Purine bases


  • Adenine
  • Guanine
• Pyrimidine bases


  • Cytosine
  • Thymine
  • Uracil
• Nucleoside


  Macromolecule composed of a nitrogenous base joined to a pentose
• Nucleotide


  Macromolecule composed of a nitrogenous base, a pentose, and linked (esterified) to one or more phosphate groups
• Phosphate is linked to the 5'-OH of the pentose in a 5'-ribonucleotide (RNA)
