In your context, “metabolite system” essentially refers to the interconnected set of small-molecule metabolites and their pathways that can be profiled (metabolomics) to assess risks such as type 2 diabetes (T2D). This is closely related to what recent T2D metabolomics research calls the human metabolome.
Definition and Components
Metabolite system (metabolome-focused usage)
- The human metabolome is “the composite of all small molecules in a biological sample,” providing insight into biochemical processes, disease states, and drug responses.1
- A metabolite system can be understood as:
- The set of metabolites (amino acids, lipids, carbohydrates, acylcarnitines, etc.) present in blood, urine, or tissues
- The biochemical pathways and networks linking their synthesis, catabolism, and interconversion
- The integrated readout of upstream genetics, organ function (pancreas, liver, adipose tissue), and environmental/lifestyle factors.12
Relation to Type 2 Diabetes
- Large prospective cohorts show that multiple classes of metabolites (branched-chain and aromatic amino acids, specific carbohydrates, acylcarnitines, glycerolipids, phospholipids, ceramides) within this system are associated with future T2D risk.2
- A recent Nature Medicine analysis identified 235 metabolites related to T2D risk and derived a 44-metabolite signature that predicts incident T2D (AUC 0.62–0.86), with ~5-fold higher risk in the top vs bottom decile.1
- These T2D-associated metabolites are genetically linked to insulin resistance, glucose–insulin dynamics, ectopic fat deposition, energy–lipid regulation, and liver function and are strongly modulated by diet, physical activity, and adiposity
