The structure of ephedrine is given, The pKa for ephedrine is 9.6. Answer the following questions about aqueous solutions of ephedrine. a. Draw the structure of the principal chemical form of ephedrine that results when it is dissolved in water. b. Draw the structure of the principal chemical form of ephedrine that results when it is dissolved in a buffer at a physiologically relevant pH of 7.4. c. Calculate the pH that results when 0.3 mole of ephedrine is dissolve in 2.0 L of 0.05 M perchloric acid (HClO4).
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
