metabolite levels
The transformation here is a chemical change and could involve making or breaking a bond in a biopolymer, or making a natural product or metabolite.
Molecular biology techniques based on the specificity of biological recognition (bio-affinity) have been extensively developed for biomarker detection (nucleic acids, proteins, lipids, other metabolites).
Voxels of this size often include in their volume multiple tissue types, which seriously complicates interpretation of metabolite levels.
Clinical comparison of selective serotonin reuptake inhibitors metabolite, but in such low concentrations as to be thought to be negligible.
Carbon-13 enrichment of hepatic metabolites decreased with time.
Expanded ontogeny of neurotransmitters and their metabolites in the brains of fetal and newborn lambs.
The presence of a variety of metabolites in the bile provides the opportunity for uptake by both diffusion and oral ingestion.
Low serotonin and dopamine metabolite concentrations in cerebrospinal fluid from bulimic patients with frequent binge episodes.
