Sažetak

Glucosinolates are unique group of secondary plant metabolites. They are specific chemical compounds i.e. phytochemicals occurring in about 16 botanical families of the order Capparales. For the human diet, the most important are representatives of the Brassicaceae
like cabbage, Brussels sprouts, broccoli, cauliflower, radish, mustard. In this review, we will elaborate all the relevant steps in the food supply chain of Brassica vegetables and their influence on intake and bioavailability of glucosinolates and bioactive breakdown products in
relation to human health. Plants possessing glucosinolates also contain an enzyme, myrosinase (β-thioglucoside glucohydrolase; EC 3.2.3.1). When glucosinolates and myrosinase come in contact with each other in the presence of water, the enzyme immediately
causes the hydrolysis of the glucosinolates. Those breakdown products of glucosinolates are also biologically active. Except consuming fresh, vegetables are often processed. Depending
on conditions during processing, degradation of glucosinolates can occur resulting in change of their bioavailability and biological activity. Numerous epidemiological studies have proven
positive influence of consumption of Brassica vegetables on human health. Glucosinolates and their enzymatic hydrolysis products have the potentially beneficial activities as antioxidants, antifungal, antibacterial, bioherbicidal, biopesticidal, antimutagenic and
anticarcinogenic agents. Next to their positive effect on human health, the antinutritional effects and the possible toxicity of glucosinolates were also observed. Those effects should
also be taken in account and there is a need for further investigation of these effects.
