Table 49. Specificity of meso-Inositol. 



Arabitol, sorbitol, dulcitol, mannitol and other sugar alcohols are inactive for yeast. 107 



* According to Posternak, 81 mytilitol is methylscyllitol, and isomytilitol is methyl-?neso-inositol. 



Schopfer 62 > 85 - 86 has tested the specificity of inositol for Rhizopus 

 suinus and the "inositolless" mutant of Neurospora crassa. Meso-inositol 

 is highly specific for both these organisms. (Table 49) 



An interesting stereochemical specificity has been observed in the rate 

 of the enzymatic oxidation of the inositols to ketones and diketones by
