Effect of okra polysaccharide on α-amylase inhibition and its spectral analysis

The effects of okra polysaccharide on α-amylase and its UV spectra were studied in the test. The results showed that okra polysaccharide had strong inhibition ability on α-amylase,the increase of its concentration,and could lead to reversible competitive inhibition. Moreover,UV spectra showed that okra polysaccharide induced a blue shift of α-amylase warelength,and increased with the increase of its concentration. These results provided that interaction occured when mixed between the okra polysaccharide and α-amylase.
