| Associated research grant: | 12/23970-2 - Biological changes of papaya pectins with possible benefits to human health, AP.JP |
Abstract Papaya is a fleshy fruit in which pectins are depolymerized in oligosaccharides throughout ripening. These compounds might exert beneficial health effects in human beings since they are consumed in a regular diet being and they are part of the soluble fibers fraction of fruits. The depolymerization of pectins is achieved by the action of hydrolases (pectinases), with polygalacturonases (PG), galactanases (GAL) and arabinanases (ARF) being the main ones. In this way, the objective of the proposed project is to analyze pectins and oligosaccharides extracted from unripe and ripe papayas and try to correlate with PGs, GALs and ARFs genes expression. The obtained results could indicate the probable sugars that are released during papaya ripening with potential benefits to human consumption. (AU) | |
