I had a fun interview with The Analytical Scientist and my friends and colleagues Coral Barbas and Georgios Theodoridis about the importance of good analytical chemistry. Please have a read of why we think that analytical chemistry needs to step into the light. 👇 tinyurl.com/mvs39c7c

#Throwback 🧪 COMMENT | Metabolites are not genes — avoiding the misuse of pathway analysis in metabolomics KS Lee, X Su & T Huan

Metabolites are not genes — avoiding the misuse of pathway analysis in metabolomics - Nature Metabolism
Pathway analysis, originally developed for gene expression data, has been adapted for metabolomics. However, owing to the unique characteristics and constraints of metabolites compared with genes, pathway analysis in metabolomics often yields misleading or nonsensical results.
