Document Summary
Large family of sulfur-containing compounds found in plant families of the order of capparales: includes the brassica family. Over 100 that differ in r group. Development of a food composition database for estimation of dietary intakes of glucosinolates- relation to overall phytochemical concept. Important to advance knowledge of phytochemicals in relation to disease risk. Data allow for more thorough and accurate quantification of glucosinolate intakes. This data can be used in epidemiological studies- assess diet and analyze for glucosinolates. Sulfate group: imparts strong acidic properties ( ate in the name, glucosinolates can occur in nature as anions counterbalanced by a cation (usually potassium) R-group is derived from amino acids and is highly variable. They differ in their r-group side chains. They are broken down by a specific type of enzymes: myrosinases, located in plant vacuoles called myrosin cells. Myrosinases and glucosinolates are separate within the plant: precise location of glucosinolates isn"t clear (thought to be vacuoles)
