Curcumin is often used as a food additive to colour the food yellow - its E number is E100 - read the food labels on the packet of food - can you find it in any foods that you enjoy?
What was discovered?
A molecule called curcumin in turmeric, which gives curry its familiar yellow colour, can destroy cancer cells of the gullet.
Why is it important?
Rates of cancer of the gullet (oesophagus) have been steadily increasing since the 1970's, so there is good reason to develop medicines to kill these cancerous cells.
Molecules found naturally in plants, like curcumin, may already be able to destroy abnormal cancer cells without harming our normal cells, so they can be quickly and easily developed as medicines.
What kind of molecule is curcumin?
Curcumin is a polyphenol, with two phenol groups
It can exist in two tautomeric forms - the keto and the enol forms
It is also called Natural yellow 3, but its systematic chemical name is
(1E,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione
Why does the plant make curcumin?
Curcuma plants make curcumin in their roots, which they also use to store food underground over winter for the new plants to use to grow the following spring.
The curcumin probably protects the food supply from being eaten by animals in the soil.
