hyde acted by virtue of its combining power with P-hydroxy butyric acid, 

 forming a new compound which is glucogenetic. We know to-day that 

 acetaldehyde is a very important product, in the Intermediary metabolism 

 of carbohydrate, and it is very likely that the antiketogenetic effect of 

 glucose is brought about through acetaldehyde-p-hydroxybutyric acid or 

 acetaldehyde-aceto-acetic acid combination.
