1. A fat molecule is composed of two types of smaller molecules, including only one molecule of_ . 2. A fat molecule also includes one, two, or three molecules. 3. A fat molecule with only one fatty acid is called a_ . 4. A fat molecule with three fatty acids is called a triacylglycerol, or a . 5. A fatty acid includes a carboxyl group (-COOH) at one end as well as a long_ . 6. The hydrocarbon chains found in fats store a lot of energy. They also make fats____ , or insoluble in water.Fill in above blanks.a. hydrophilic b. fatty acid c. triglyceride d. monoglyceride e. glycerol f. hydrocarbon chain g. hydrophobic

A fat molecule is made up of two parts with one part been the glycerol backbone and three fatty acid tails. A fat molecule with just one fatty acid chain can be regarded as a monoglyceride and with three fatty acids, you have a triglycerides.

One end of the fatty acid is made up of even number carbon-carbon chains at one end and the -COOH on the other end making it a carboxylic acid. The hyrocarbon chains of the fatty acid is hydrophobic in nature and always cluster up in molecules such as in the biological cell meembrane.
