The authors focused their attention on three essential molecules belonging to this primordial group of ubiquitary chemical compounds: myoinositol and D-chiroinositol, two stereoisomeric forms of inositol(s), and inositol hexakisphosphate, a metabolite of myoinositol.
Also, myoinositol and its metabolite, inositol hexakisphosphate, deserve to be carefully taken into consideration.
Two isomers of inositol hexakisphosphate were detected, though not in all soils: peaks at 4.2, 4.3 and 4.7 ppm were assigned to the myo-isomer (phytate), while a peak at 3.85-3.91 ppm was assigned to the scyllo isomer (Turner and Richardson 2004; Turner et al.
All other detected species represented small proportions of total signal; on average, these species represented the following percentages of total P in NaOH-EDTA extracts: 3% (lipid P); 1% (RNA P); 2% inositol hexakisphosphate (phyate rscyllo-\?(ty, 2% diester P; 2% pyrophosphate.
