Chemical and biological studies of -carotene after exposure to smoke.

Considering the increase in consumption of and the use of the compound carotene (BC) as supplement, we investigated potential changes in the chemical and biological proprieties of BC after exposure to smoke (CSS). Our results showed that the BC exposed to CSS underwent 98.8% degradation and suffered loss of its antiradical activity.
