TABLE Vb. Behaviour of bdain in acidic solution. 



The summary of the above mentioned results becomes as follows : 



1. Amino acetic acid and a amino propionic acid retard the 

 destruction of glucose by sodiumhydroxide. 



2. This phenomenon is independent of the presence and the 

 quality of the monosaccharid, for the destruction of galactose by 

 sodium-hydroxide is retarded too by the substance mentioned. 



3. Amino acetic acid and .^-aminopropionic acid behave in alkalic 

 medium as acids. By further examination it was demonstrated that 

 they behaved as about one-basic acid. 



4. Just on the otfier hand the.se aminoacids in presence of hydro- 

 chloric acid behave as monacidic alkali, so that they considerably
