The history of the airplane shows it was invented by Orville (1871-1948) and Wilbur (1867-1912) Wright. They got the patent 9 months prior to their flight in December 1903. The Early History of Flight. There are pictures showing Orville Wright on the plane flying.
Naturally occurring pectin is a soluble fiber found in many fruits and plants. Pectin is a great example of a natural polymer, and is composed of pectic acid and pectinic acid molecules. It is basically a compound with a bunch of sugars and acids attached to it. (I always find the chemical structure fun!) Every plant contains some amount, sometimes just a very small amount, of pectin.
Pectin is a soluble fiber found in most plants. In food, it is most commonly used to thicken jams, jellies, and preserves. The human body cannot digest pectin in its natural form. But an altered form of pectin, known as modified citrus pectin (MCP), has properties that allow it to be digested.
