Origin of amino acid homochirality: Relationship with the RNA world
... (Fig. 2). 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 ...
