Fats and oils are made from two kinds of molecules: glycerol (a type of alcohol with a hydroxyl group on each of its three carbons) and three fatty acids joined by dehydration synthesis. Since there are three fatty acids attached, these are known as triglycerides. “Bread” and pastries from a “bread factory” often con- tain mono- and diglycerides as “dough conditioners.” Can you figure out what these molecules would look like? The main distinction between fats and oils is whether they’re solid or liquid at room temperature, and this, as we’ll soon see, is based on differences in the structures of the fatty acids they contain.
Inorganic Molecules Northwest ISD By: Josiah Hernandez Inorganic Molecules are not 50% OFF very complex and are usually found in nonliving things. An ex- ample is a diamond because it contains just carbon and not hy- drogen. Oxygen and carbon diox- ide are two major inorganic sub- stances. They are important be- cause they deal with respiration and without respiration we wouldn’t be living. Gatlin.IncTel: 555 555 5555
