Formation of high molecular weight products in the presence of fructose. a Formation of protein cross-links in presence of fructose. SDS-PAGE was conducted with the aliquots collected at day 6. MW: Molecular weight markers, −P: in the presence of fructose without plant extracts or AG. This observation was made on varying incubation periods for more than 100 times. b Progress of protein cross-linking over time in the presence of fructose. SDS-PAGE was conducted with the aliquots collected at day 1 (D1), day 2 (D2) and day 6 (D6) from lysozyme incubated with fructose in absence of plant extracts or AG. Experiment was repeated three times
