Extended Data Fig. 2: iglu#93 is an indole glycoside produced by wild strains but not by the N2 reference strain.
From: C. elegans as a model for inter-individual variation in metabolism
a, Quantification of indole glycoside iglu#93 in exo-metabolome extracts of the four strains. Data represent six biologically independent experiments and bars indicate mean ± s.d. p-values calculated by unpaired, two-sided t-test with Welch correction. b, Major fragmentation reactions of m/z 498.1983 (negative ion mode) and resulting fragment ions representing free indole and indole glycoside. Fragmentation is consistent with a deoxy-dimethyl sugar moiety, such as di-O-methylfucose50. c, Proposed structure of iglu#93. Stereochemistry and exact substitution patterns are unknown. Source data are provided as a Source Data file.
