3,4,5,6-Tetrahydrohippuric acid
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
The rat tracer study recovered shikimate-derived carbon in tetrahydrohippuric-acid.
Experimental context and source evidence

**Gut metabolism and host conjugation must be distinguished.** The 1978 rat study traced oral shikimic acid into urinary hippurate, hexahydrohippurate, tetrahydrohippurate, two dihydroxycyclohexanecarboxylate isomers, catechol conjugates and expired CO2. Antibiotic treatment suppressed the characteristic conversion, implicating initial gut-microbial transformations. Host metabolism of microbial products still occurs. Hippurate contains a glycine conjugate, but product detection does not establish clinically significant glycine depletion or an identical human quantitative pathway. No assertion that parent shikimic acid is directly converted to every final product in one reaction is made. [The metabolism of shikimate in the rat.](https://pubmed.ncbi.nlm.nih.gov/637841/)
