Pectin from various parts of lemon, grapefruit, tangerine, and orange were isolated and characterized Tangerine had the highest pectin content among the four citrus species. Segment membrane contained as much as or more pectin than flavedo\/albedo. Anhydrogalacturonic content was highest in pectin from segment membrane of tangerine and flavedo\/albedo of grapefruit. Lemon pectin contained the highest methoxyl content (MC), and grapefruit contained the largest proportion of lower molecular weight (&lt; 10000 Da) pectin. Tangerine contained the highest neutral sugar in both flavedo\/albedo and segment membrane. The interdependency of heparin on factor-receptor interaction provides a means for identifying new antagonists of growth factor activity and thus for treatment of various diseases. These results showed that pectin significantly inhibited the binding of FGF-1 to FGFR1 in the presence of 0.1 mug\/mL heparin. The pectin from the segment membrane of lemon was the most potent inhibitor. The inhibition activity was significantly correlated with sugar content, MC, and size of pectin. Kinetic studies revealed a competitive nature of pectin inhibition with the heparin, a crucial component of the FGF signal transduction process. The observation that the heparin-dependent biological activity of FGF signal transduction is antagonized by citrus pectin should be further investigated for the use of these pectins as anti-growth factor agents for potential health benefits.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-56591","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"PATIL BS,TEXAS A&M UNIV,KINGSVILLE
