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.

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 acts on

  1. PLP-dependent garlic alliinase cleaves alliin to the sulfenic-acid precursor; aminoacrylate formation leads to pyruvate and ammonia.

    **Alliinase and vitamin B6.** Garlic alliinase is a plant pyridoxal-5′-phosphate (PLP)-dependent enzyme, not a human enzyme. Structural studies resolved its cofactor-containing active site, an apo form, and a PLP-bound aminoacrylate intermediate. Alliin cleavage produces allylsulfenic acid and an aminoacrylate intermediate; the latter yields pyruvate and ammonia. Two allylsulfenic acid molecules condense to allicin with water loss. This links allicin formation to B6 chemistry in the plant. It does not show that taking B6 increases allicin production in a person.

What acts on it

  1. Alliinase localization to garlic bundle-sheath cells qualifies where precursor-enzyme mixing occurs after tissue damage.

    **Plant anatomy.** Alliinase was strongly localized to garlic-clove bundle-sheath cells, particularly around phloem, with little detected in storage mesophyll away from vascular bundles. Tissue disruption permits precursor–enzyme contact, but a uniform arrangement in every garlic cell is an oversimplification. Intact garlic still contains active metabolism and other constituents.

Where it participates (unsigned role)

  1. Garlic alliinase is a PLP-dependent plant enzyme; its structural cofactor requirement is not a human B6 supplementation experiment.
