The Chemical Building Blocks of Life
... Carbon and hydrogen atoms both have very similar electronegativities, so electrons in C—C and C—H bonds are evenly distributed, and there are no significant differences in charge over the molecular surface. For this reason, hydrocarbons are nonpolar. Most organic molecules that are produced by cells ...

The rationale was that since the free energy of aminoacyl phosphates hydrolysis is approximately 3 kcal mol−1 greater than that of the aminoacyl esters (aminoacyl-tRNAs) (Carpenter, 1960), aminoacylation would be spontaneous. This system aminoacylated the minihelix at the 3 -end and the c ...
