Glucosinolates
Glucosinolates
These may be related to cyanogenic glycosides in biosynthesis
limited distributions in families
pathway is not as well worked out as that for cyanogenic glycosides, but also from several aa's also incorporation at extremely high levels
breakdown products are more or less volatile
S-glucosides,"myrosinases" break them down
Indole glycosides very sensitive
often missed in analyses
Distribution
Brassicaceae
Capparidaceae
Tovariaceae
Resedaceae
Tropaeolaceae
Limnanthaceae
Carica papaya
often involved in plant-insect interactions, many crop plants
carcinogenic or not?
broccoli, other brassicaceous crop plants
goitrigenic compounds
Pieris rapae
oviposits on Cardamine cordifolia in some sites, but not others
extract of Erysimum cheiranthoides ... then they won't accept plants that they usually will ... cardiac glycosides
need a balance of stimulants and repellents
