As shown before, the rational formula for the amylogen group 

 is some multiple of 



Ci8H270i2"03' (Ci2H230ii)3 



and by making use of Fischer's formula for maitose, Synkiewski 

 writes the graphic formula for amylogen as f ollows : 



^^\CH(CHOH)4CH2— O— CH(CH0H)rCHCH0HCH20H 



/ "^\CH(CH0H)4CH2— O— CH(CHOH)2CHCHOHCH20H 

 C18H27O12 O^ 



\^Q>CH(CHOH)4CH2— 0-CH(CHOH)2CHCHOHCH20H 



Synkiewski suggested that this formula represents a half acetal of 

 the ten-hydroxyl alcohol of maitose, which is analogous to the alco- 

 holates of chloral ; and that it might be named " tri-malto tri-glu- 

 cosate," if the not impossible but as yet undiscovered triglucose 

 sugar were known to exist. 



In Order to combine all facts, including a ring combination of 

 the three glucose molecules, Synkiewski shows that the formula for 

 the amylogen nucleus could be written in accord with the arrange- 

 ment shown in Fig. 3, on p. 392.
