Untargeted Metabolomics Reveals Seasonal and Tissue‐Specific Metabolic Shifts in Holothuria cinerascens

Chemistry &Biodiversity, EarlyView.
Untargeted metabolic profiling of three body tissues from Holothuria cinerascens in South Africa using 1H‐NMR and UPLC–QTOF–MS revealed distinct tissue‐specific and seasonal metabolic variations, with the body wall and gut/mesentery exhibiting high metabolite diversity.
