chemical ecology of food Flashcards
chemical ecology
the study of chemicals involved in the interactions of living organisms
secondary metabolites
organic compounds not directly involved in basic survival of the organisms
roles of secondary metabolites in plants
-defense
-competitive warfare
-pollinator attraction
-dispersal
-plant color, flavor, & odor
phenolic
aromatic ring with one or more hydroxyl groups
quinones
can inactivate proteins, browning in fruits & vegetables
flavonoids
plants response to infection, yellow or orange pigment, attract pollinators, & antioxidant
anthocyanins
produce the dark blue color in plants
flavonoids can be both
aglycone and glycosides
resveratrol
produced by fermented grape skins, red wine
coumarins
anti thrombotic, anti-inflammatory, and vasodilatory activity
tannins
tan leather, astringent, anti-diarrheic
psoralens
coumarins, citrus & carrot families, used in skin treatments.
alkaloids
contain nitrogen group
terpenoids
plant fragrance, microbial
lectins and polypeptides
bind to sugars, competition against microbial proteins
