Structure and properties of fatty acids
WebTriglycerides, or fats, are formed from the combination of glycerol and three fatty acid molecules. Triglycerides are formed through dehydration reactions. Another word for … Web1 day ago · Carbon's importance comes mainly from the enormous variety of structures that it can form due to its unusual four valence electrons. Most important of these structures is the carbon chain, which forms the "backbone" of fatty acids and carbohydrates, among other organic molecules. Other elements do share properties similar to carbon, in this regard.
