Nicotine

2007-07-20 01:02:46 · answer #2 · answered by Anonymous · 0 0

I think you have your answer, but I thought that I'd drop this in.

When working as a lab technician in a technical college as a summer job, I had to do a stock take of the chemicals. I had to inspect each bottle, and document the quantity and concentrations.

There were some dangerous chemicals that were in locked 'restricted' cupboards and there were a handful of small bottles where the real nasties were held, in a locked cupboard in a locked cupboard. I was under strict instruction that I could take out and inspect all of the bottles in this cupboard, except for the one on the left. That was the nicotine!!

Knowing the horrible effects of the other nasties that I was allowed to touch, it really put it in perspective. I have been vehemently opposed to smoking ever since.

Nicotine is an alkaloid found in the nightshade family of plants (Solanaceae), predominantly in tobacco, and in lower quantities in tomato, potato, eggplant (aubergine), and green pepper. Nicotine alkaloids are also found in the leaves of the coca plant. Nicotine constitutes 0.3 to 5% of the tobacco plant by dry weight, with biosynthesis taking place in the roots, and accumulating in the leaves. It is a potent neurotoxin with particular specificity to insects; therefore nicotine was widely used as an insecticide in the past, and currently nicotine derivatives such as imidacloprid continue to be widely used.

In low concentrations (an average cigarette yields about 1mg of absorbed nicotine), the substance acts as a stimulant in mammals and is one of the main factors responsible for the dependence-forming properties of tobacco smoking. According to the American Heart Association, "Nicotine addiction has historically been one of the hardest addictions to break." Nicotine is one of the most addictive substances known to man. In heavy smokers, the addiction can be comparable to the extremely potent drugs cocaine, and even heroin in terms of addiction intensity.[1]

History and name

Nicotine is named after the tobacco plant Nicotiana tabacum, which in turn is named after Jean Nicot, a French ambassador, who sent tobacco and seeds from Portugal to Paris in 1550 and promoted their medicinal use. Nicotine was first isolated from the tobacco plant in 1828 by German chemists Posselt & Reimann. Its chemical empirical formula was described by Melsens in 1843, and it was first synthesized by A. Pictet and Crepieux in 1893.

No, proper nouns have specific names. Marlboro Cigarettes is a proper noun, while cigarettes is just a regular noun.
