Similarly, the band at 1440 [cm.sup.-1] associated with [v.sub.s] (O=C-O) vibration of nonesterified groups in pectin was also overlapped with more intensive peak at 1419 [cm.sup.-1], which is typical for vs (COO-) of salts of pectic acid. Moreover, bands typical for deformation vibrations of absorbed water [delta] ([H.sub.2]O) (the signal around 1650 [cm.sup.-1]) could also influence on the bands in the region from 1600 [cm.sup.-1] to 1700 [cm.sup.-1], similar to the report of Chylinska et al.

Plant cell wall can be categorized into 3 layers: layer one is adhesive between cell and another called "middle lamella" composed of calcium pectate (pectic acid binding [Ca.sup.2+]), layer two is a real cell wall synthesized during cell division called "primary cell wall" composed of cellulose, hemicellulose, and pectic substances, and layer three synthesized after primary cell wall or in nongrowing stage of cell called "secondary cell wall" composed of cellulose, hemicellulose, and lignin [27, 28].
