Structural diversification during glucosinolate breakdown: mechanisms of thiocyanate, epithionitrile and simple nitrile formation. [PDF]
SummarySecondary metabolism is characterized by an impressive structural diversity. Here, we have addressed the mechanisms underlying structural diversification upon damage‐induced activation of glucosinolates, a group of thioglucosides found in the Brassicales.

Metabolism and Recovery of Epithionitriles from Glucosinolates—A Human Intervention Study
ScopeEpithionitriles can be main glucosinolate hydrolysis products in Brassica vegetables such as cabbage or pak choi. Here, for the first time, the bioavailability and metabolism of longer‐chain epithionitriles (C4–C5) is studied in a human intervention study.Methods and resultsAfter consumption of a white cabbage or pak choi sprouts beverage, rich in

Identification Of N-Acetyl-S-(3-Cyano-2-(Methylsulfanyl)Propyl-Cysteine as a Major Human Urine Metabolite from the Epithionitrile 1-Cyano-2,3-Epithiopropane, the Main Glucosinolate Hydrolysis Product from Cabbage. [PDF]
Brassica vegetables such as cabbage or pak choi contain alkenyl glucosinolates which can release epithionitriles and to a lesser degree isothiocyanates upon enzymatic hydrolysis. Here, for the first time, the metabolism of an epithionitrile was investigated in humans, namely 1-cyano-2,3-epithiopropane (CETP). After consumption of Brassica oleracea var.

Development of a Gas Chromatography-Time-of-Flight Method for Detecting Glucosinolate Metabolites and Volatile Organic Compounds in Kimchi. [PDF]
This study examined the volatile organic compounds (VOCs) and metabolites of glucosinolate (GLS) contained in kimchi and analyzed GLS using myrosinase. The analysis was conducted using gas chromatography‐time of flight (GC‐TOF), and VOC and the metabolite quantities were detected and analyzed.

Sulforaphane and ophthalmic diseases. [PDF]
Sulforaphane (SFN) is an organosulfur compound categorized as an isothiocyanate (ITC), primarily extracted from cruciferous vegetables like broccoli and cabbage. This review comprehensively outlines recent research on SFN, elucidates its mechanisms of action, and discusses potential therapeutic benefits for eye disorders such as age‐related macular ...

Cooked Broccoli Alters Cecal Microbiota and Impacts Microbial Metabolism of Glucoraphanin in Lean and Obese Mice. [PDF]
Seven‐day cooked broccoli feeding increased the ability of the gut microbiota to metabolize glucoraphanin (GRP) into beneficial isothiocyanates (ITCs) leading to increased colonic NQO1 activity. Gut microbiota shifted, with Lachnospiraceae NK4A136 group and Dubosiella newyorkensis increasing on broccoli diet.
