Early Work on the Structure of Pectin

Ehrlich was one of the first workers to attempt a detailed chemical investigation of pectin. He subdivided pectic materials into groups  

2 moles methyl alcohol 2 moles acetic acid D-Galactose L-Arabinose 

More recently, the chemical structure of the components of pectic materials has been investigated by the present writers, whose approach 

In view, however, of the most recent work on the structure of xylan, - which has been shown to contain combined L-arabofuranose residues in 

Pyranose and furanose forms of the methyl glycoside of 2,3-dimethyl-n-galacturonic
