<applet load='Adenosine.pdb' size='300' frame='true' align='right' scene ='User:Karl_Oberholser/Sandbox_1/First_view/1'/> Observe that the adenine ring of adenosine is nearly perpendicular to the furanose ring and that a <scene name='User:Karl_Oberholser/Sandbox_1/Glycosidic_bond/1'>β glycosidic bond</scene> (colored green) connects adenine to ribofuranose. Groups on the ribofuranose, such as the hydrogen on the 2' carbon sterically hinder the rotation of the adenine about the glycosidic bond. This lack of ability to rotate results in two possible configurations. The <scene name='User:Karl_Oberholser/Sandbox_1/Anti_configuration/1'>''anti'' configuration </scene> which you have been viewing. shows the and when displayed in spacefill one can see that the <font color=orange> hydrogen </font> of the 2' carbon hinders the rotation of the purine ring about the glycosidic bond.
