Anthocyanin glucuronidation in rat liver microsomes
Anthocyanin glucuronidation in rat liver microsomes. Interpret through the linked experimental species, preparation, compartment and exposure; no universal causal effect is implied.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
Separate rat microsomal experiments glucuronidated anthocyanins when activated glucuronic acid was supplied.
Experimental context and source evidence
- evidence_access
- Primary indexed abstract reviewed; full methods, figures, exact doses or endpoint-specific species assignments may remain unextracted.
- experimental_model
- Rat liver microsomes with activated glucuronic acid; no inference to a specific human UGT isoform.
- interpretation_status
- Source-derived extraction of a fact-checked reference; access is explicit, not independent raw-data verification.
- limitations
- Interpret only within the recorded preparation, exposure and comparator. The complete source passage retains qualifications; unspecified doses/timing have not been extracted here. No clinical efficacy, nutrient deficiency or unique molecular mediation is inferred.

**Microbial cleavage and host conjugation are distinct steps.** Anaerobic human fecal incubations degraded glycosylated and acylated anthocyanins to B-ring-derived phenolic acids. Separate rat-liver microsome experiments produced glucuronides when supplied with activated glucuronic acid; the tested NADPH-supported P450 system did not hydroxylate or demethylate the pigments. These are model-specific positive and negative findings, not proof that all human metabolism is exclusively microbial or that every CYP interaction is absent.
