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 naturally occurring carbohydrate in fruit that is concentrated in the fruit's skin and the core. When cooked, Pectin solidifies to a gel, causing fruit preserves to set.Fruit uses Pectin to build cell walls with.o test to see how much Pectin is present in a fruit juice or stewed-down fruit, put 1 tablespoon of rubbing alcohol into a glass, and add 1 tablespoon of juice from the fruit (allow the juice to cool for a minute or two first), and let stand for 2 to 3 minutes. A jelly-like blob should form.
