November phytochemicals: the smell of garlic and the color of mac and cheese

Running a bit behind on the phytochemicals... but never fear: we'll catch up!
Happy #PhytochemicalFriday (and Halloween)! Today: diarylheptanoids - compounds found in various plants, including Tacca chantrieri (black bat flower: spooky!). This class of compounds includes curcumin (turmeric), and cyclic compounds (dotted orange bond) - many are antioxidants.

Happy #PhytochemicalFriday! Today: allicin, a (zwitterionic!) compound from garlic. Normal garlic cells contain alliin (an amino acid-like compound), but crushing garlic exposes alliin to an enzyme that converts it into allicin - the major contributor to the aroma of fresh garlic.

Bixin! An apocarotenoid from Bixa orellana (achiote) - a compound in the food additive annatto - an orange/red extract from achiote seeds. As ground seed, this compound is used in many South and Central American dishes and is used to color Gloucester cheese! #PhytochemicalFriday.

Galantamine, alkaloid from Galanthus spp. (snowdrops; Amaryllidaceae, perhaps antidote to Circe's poisons in Homer's Odyssey), not only has a very cool tetracyclic structure, but has been used to treat cognitive decline (Alzheimer's disease) and autism. #PhytochemicalFriday.
