Acylated sterol glycosides (ASG) and sterol glycosides were found to increase consistently as the free sterols decrease in bean leaves exposed to ozone. The following fatty acids were detected in bean leaf ASG analyzed by separating the methyl esters by gas-liquid chromatography: palmitic, stearic, oleic, linoleic, and linolenic. All these fatty acid components increase in the ASG of ozonated leaves, with a major increase in linolenic acid. Ozone increases cell permeability. Sterols and their derivatives are important components of cellular membranes, and these changes may be one step in ozone toxicity. 9 references.
