1. Atoms and bonds. Adenosine 5-triphosphate (ATP) is one of the important biomolecules in all living cells. structure serves as review of your prior knowledge of organic chemistry A) Using a pencil, draw the stereospecific structure of ATP. Be sure to show all atoms and all bonds (sce page 116 ol your textbook) NH₂ 10 DH B) In the structure you have drawn above, differentiate between polar and non-polar atoms. [Using a red pen, write partial and full electric charges on polar atoms: & St, l- and I+. Using a blue pen, draw circles around non polar atoms. ] C) In the structure above, number the atoms in the base and sugar. Indicate the chiral carbon atoms with a star (*). D) Below, list the major chemical groups (carbonyl, amino, alcohol, etc.) and chemical bonds (ester, glycosidic, phosphoanhydride, etc.) found in ATP.

Answer 1

NH, A and B) Structure of ATP: a 08 08 08 A N stvo 6+! :02P-o-po-osto LH HV 07 H &+ To+ OHHOS

NH2 c) Numbering: Zv o=P-o-Ⓡ-O-P-0–5. ONA Ņ2 * 1' 12 OHHO D) Functional groups: The base is Adenonine, that contains purin ring and one amino group at C6 position. Sugar part of ATP is ribose sugar, that contains two free hydroxyl groups. Triphospate is phosphate ester chain of three phosphate groups.
