The uronic acid
of RGP1, RGP2, RGP3, and RGP4 were 4.2, 13.6, 17.8, and 8.4%, respectively.
The composition of neutral sugars and uronic acids
and the molecular weights of the hemicellulosic samples were determined according to the literature .
Dietary fibre in blackberries and raspberries consisted mainly of polymers containing glucose (38%-40%), uronic acids
(29%-31%), and xylose (16%-20%).
The residual GAG oligosaccharides coupled to the proteoglycan peptide have a 4,5-unsaturated uronic acid
residue at the non-reducing terminus (Fig.
These junction zones are stabilized by interchain hydrogen bonds between the carboxylic group of uronic acid
and by hydrophobic interactions between methylester groups .
The result indicated that BCPs contained 51.20% of total carbohydrate, 48.47% of uronic acid
and 2.61% of protein.
content of the antler was determined by the method of Scott (1960) and Kosakaki and Yosizawa (1979).
Principal Component 4 with its strong uronic acid
component was correlated with seed weight (Table 2) and was used in the regression equation (Table 5).
This could be explained by the high uronic acid
content or HG presence in the sample.
The bands at 3420, 2931, and 1623 [cm.sup.-1] represent the stretching vibrations of O-H, C-H, and -CO[O.sup.-] (asymmetric vibrations) groups, respectively, in carbohydrate and uronic acid
Polysaccharides from Caulerpaceae consisted mainly of galactose and sulfate, small amount of arabinose, xylose, manose and uronic acid
(HAYAKAWA et al., 2000; GHOSH et al., 2004; CHATTOPADHYAY et al., 2007; JI et al., 2008; SCHEVCHENKO et al., 2009) .
