Ibuprofen

It is a non-steroidal anti-inflammatory drug or (NSAID). Because it has a different chemical structure to steroids, it is not as toxic.

It reduces pain by targeting compounds called prostaglandins which cause inflammation in the body.

Tropinone

Tropinone is a key member of the tropane alkaloid class of neutral products. From it one could obtain numerous congeners such as cocaine or atropine, a deadly poison but also used as a muscle relaxant in surgery.

When atropine was needed to overcome the effects of nerve gases during World War I, very little was available. That’s when Britain’s Sir Robert Robinson developed his classic one-pot, concerted synthesis of tropinone. To this day, tropinone’s only practical use is as a precursor to atropine. Robinson was awarded the 1947 Nobel Prize in Chemistry—however, not for his tropinone synthesis.

Quinine

Quinine is an alkaloid which can reduce fever, work against malaria, pain and swelling.

Quinine has a bitter taste. Classic tonic water is carbonated water infused with quinine. For added taste sometimes sugar or fruit acids are mixed in. The higher the level of quinine in the water, the more bitter it tastes. Legends claim, that the first type of quinine water was used in the British colonies of India in the 17th century.

In night clubs gin and tonic can glow a pale blue colour under the UV lights. This is due to the quinine in the tonic water being excited by the UV light

Morphine

Morphine is the main constituent of opium. Morphine was found in the Asian poppy plant. It has been used for over 6000 years as a way to treat pain and for its euphoric effects.

Morphine acts on the opioid receptors in the brain and central nervous system, reducing the perception of pain and the emotional response to the pain. Morphine has been part of American society since before the Civil War, where it was used to treat the soldiers’ pain from their battle injuries.

Using the drug for longer periods of time and can quickly lead to addiction. Morphine addiction develops when the brain begins to depend on the drug for the feelings it produces. When heroin enters the brain, it is converted back to morphine, so people struggling with addiction to heroin and other opiates are also addicted to morphine.

Cholesterol

Cholesterol from the Ancient Greek chole- (bile) and stereos (solid) is an organic molecule. It is a sterol (or modified steroid), a type of lipid. Cholesterol is biosynthesized by all animal cells and is an essential structural component of animal cell membranes.

1. Seventy-five percent of your total cholesterol arises naturally from your body (it's produced by your liver).

2. Your body needs cholesterol to perform valuable functions but doesn't need dietary cholesterol to do its job. It may take the blame for causing arterial blockages that can lead to heart disease and stroke, but cholesterol is essential for maintaining healthy cell walls and producing vitamin D as well as the sex hormones androgen and estrogen.

3. And the fact is, your body produces enough cholesterol to handle all these jobs; you don't need the cholesterol you get from food for your body to operate properly.

4. There's "good" cholesterol — high-density lipoproteins, or HDLs — and "bad" cholesterol, LDLs. Add them together and you get your total cholesterol.
