Does the study of metabolites from biological fluids (blood, urine and tissues) only comes under metabolomics? or does the investigation of plant metabolites by various techniques like LC, LC-MS and NMR etc also belong metabolomics.
technically speaking, the study of metabolites through analytical technologies is to be called metabolomics. But it depends on the researchers what name they want to give to their study.
Yes, our colleague is right. For example, some authors consider metabonomics the study of biological fluid metabolites by analytical techniques (LC-MS or NMR-based techniques). However, metabolomics is the study of metabolites.
Metabolomics deals with the study of metabolites present at some instance in living cell/tissue/organ/organism. Its basically the profiling of metabolites present at some stage of life/stress/disease etc. You'l be going to incorporate your transcriptome and proteome with your metabolome to elucidate the effect of stress/disease/stimulus/condition.
You can use different analytical approaches and tools to work out the metabolome.
All the investigation of a large group of micro molecular substances can be called metabolomics, whatever the samples are plasma, cultured cells and even processed beverage and food.
