This study explores the roles of various enzymes, including PpLOX1, PpLOX2, PpAOS1, and PpAOS2, as well as non-enzymatic processes in the hydrolysis and cyclization of fatty acid derivatives. We examine the formation of key compounds such as 12,13-EOT, 11,12-EETE, and cyclopentenone derivatives, emphasizing the significance of α-ketols and γ-ketols in plant metabolism. Understanding these pathways enhances our knowledge of plant biochemistry and their responses to environmental stimuli.
