Therefore, the ions appear to be cutinase generated and their distribution represents the spatial sites of the ester bonds that are hydrolyzed to release these subfragments. The parallel negative ion mode analysis of these samples, identified those hydroxy-FAs that were not dansylated, because these hydroxyl-groups were involved in the ester bonds that constitute the intact cutin polymer. This strategy identified the hydroxyl-groups of 10,dihydroxy, 9,10,trihydroxy and 9,10,trihydroxy FAs that are not involved in cross-esterification in the intact polymer and are were thus available for alkylation. In this study, we applied methods that can systematically characterize the bonding connections and patterns of the monomeric units within cutin by the combined use of cutin hydrolytic enzymes cutinases and high-resolution mass spectrometry. The systematic application of this strategy can greatly facilitate understanding the chemical architecture of this complex polymer.

Stable-isotope labeling analysis has been used to discover new metabolic A wide range of plant material, from single cells to whole plants, can be used to.
First, these molecular ions are located in the areas that have been treated with the cutinase enzyme, and the intensity of the generated ions is dependent on the concentration of the cutinase enzyme that was applied to that area.

Forty-three cutinases were selected for additional molecular studies, and these broadly represented the clusters. We submit that the systematic application of these methods will enable the construction of more accurate architectural models of cutin, which is a prerequisite to identifying cutin-biosynthetic components.
