Sorbitol 248-256 phospholipase A2 group IVA Homo sapiens 99-106 10567216-12 1999 Both H(2)O(2) and sorbitol increased phosphorylation of cytosolic phospholipase A(2) (cPLA(2)) and its intrinsic activity; both responses were blocked by SB 203580. Sorbitol 18-26 phospholipase A2 group IVA Homo sapiens 56-93
