How to make ethanol
By: Allegria Andretti
The alcohol ethanol, C2H5OH, can be produced in two ways, by fermentation and from crude oil. In ethanol fermentation, yeast is used to break down glucose and other sugars into ethanol and carbon dioxide. The glucose and other sugars used in this process come from...
What is a lipid molecule?
By: Tami Port MS
Lipids are organic molecules that are hydrophobic or insoluble in water because the non-polar, covalent bonds linking carbon and hydrogen aren't attracted to the polar bonds of water. The four major categories of lipids include fats, phospholipids, waxes and steroids.* Fats *Fats and oils...

Organic molecules are the chemicals of life, compounds composed of more than one type of element, that are found in, and produced by, living organisms. The feature that distinguishes an organic from inorganic molecule is that organic contain carbon-hydrogen bonds, whereas inorganic molecules do not...
