2026-06-15 A provenance-linked marine lipid MS/MS resource for structural trait evidence doi:10.57760/sciencedb.39857 en This dataset contains a provenance-linked marine lipid MS/MS evidence resource built around 830,423 representative MS/MS spectra. The release includes representative spectra, spectrum linkage indexes, source provenance records, strict retrieval evidence, dual-branch lipid candidate–trait evidence, parser correction audit records, blank-aware Q1 MS1 extracted-ion-chromatogram relative abundance anchors, PE-related evidence dossier records, scope-governance tables, claim–evidence matrices, manifests, checksums and source-license summaries. Candidate–trait records are provided as structured evidence rather than confirmed molecular identities. Q1 XIC records are relative abundance anchors rather than absolute quantification. Derived machine-learning views are provided for downstream reuse without model-performance claims. marine lipidomics; MS/MS; mass spectrometry; lipid structural traits; provenance; spectral evidence; retrieval evidence; parser audit; relative XIC; machine-learning views xiong xingchuang Yinchu Wang Wei Zhang Heng Zhou PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
