The chromatograms showed 
clear indication of hydrolysis as indicated by improve in quantity and intensity of peaks of your hydrolysates. RH showed four distinct peaks on comprehensive elution, where as RH showed only 3 distinctive pea
ks with varying intensities. The peak corresponding towards the third group of components (F) was absent or merged with the fourth peak (F) in the case of RH. The intensity of very first peak (F) which corresponds to high molecular weight element was lower in RH in comparison with that of RH, and JNJ-63533054 eluted incredibly close to that of RH. Alternatively, the second peak (F) was eluted at larger elution volume in RH and the peak intensity was a lot larger than that of RH. In each the hydrolysates, the fourth peak representing the low molecular weight elements was eluted at almost similar volumes, even so, the intensity was a 
great deal higher for RH. Additional, the average molecular weight of peptides corresponding for the peaks was calculated. The initial peak eluted coincided using the molecular weight of . and . kDa for RH andRH respectively. The molecular weight in the components eluted at greater volumes couldn’t be determined as they were low molecular weight peptides which could not be HA15 extrapolated from the typical curve fitted using the molecular weight markers. From the chromatogram, it could be concluded that, RH contained a lot more medium and modest molecular weight peptides, whereas, RH contained a lot more higher molecular weight peptides. SDS Page Evaluation The molecular weight distribution with the hydrolysates was further confirmed by SDSPAGE pattern. The electrophoretic pattern indicated two intense bands at molecular weight region of kDa and under . kDa for RH, whereas the bands were not clearly visible for RH (Fig. b). This could be mainly because, the concentration of higher molecular components was much less in RH as revealed by gelfiltration profile, and these may have further undergone reduction within the presence of SDS. Higher proportion of shorter peptides under . kDa has been reported previously for catla roe hydrolysate with alcalase for min (Balaswamy et al.).

The chromatograms showed clear indication of hydrolysis as indicated by raise in number and intensity of peaks from the hydrolysates. RH showed 4 distinct peaks on complete elution, exactly where as RH showed only three diverse pea
ks with varying intensities. The peak corresponding to the third group of elements (F) was absent or merged together with the fourth peak (F) inside the case of RH. The intensity of first peak (F) which corresponds to higher molecular weight component was decrease in RH compared to that of RH, and eluted extremely close to that of RH. On the other hand, the second peak (F) was eluted at higher elution volume in RH along with the peak intensity was a great deal higher than that of RH. In both the hydrolysates, the fourth peak representing the low molecular weight components was eluted at just about equivalent volumes, nevertheless, the intensity was a lot larger for RH. Further, the average molecular weight of peptides corresponding towards the peaks was calculated. The first peak eluted coincided together with the molecular weight of . and . kDa for RH andRH respectively. The molecular weight of your elements eluted at larger volumes couldn’t be determined as they had been low molecular weight peptides which couldn’t be extrapolated in the regular curve fitted working with the molecular weight markers. In the chromatogram, it can be concluded that, RH contained additional medium and compact molecular weight peptides, whereas, RH contained additional high molecular weight peptides. SDS Web page Analysis The molecular weight distribution from the hydrolysates was additional confirmed by SDSPAGE pattern. The electrophoretic pattern indicated two intense bands at molecular weight area of kDa and below . kDa for RH, whereas the bands weren’t clearly visible for RH (Fig. b). This can be because, the concentration of high molecular elements was significantly less in RH as revealed by gelfiltration profile, and these may possibly have additional undergone reduction in the presence of SDS.
