Lipids or fats are relatively large molecules that pack a high-calorie wallop (over 9 kilocalories per gram, compared with about 4 kilocalories per gram for either carbohydrates or proteins). While that's great if your body's storing fat to make it through food shortage (imagine how much more you'd weigh if your body had to store an equivalent amount of energy in the form of carbohydrates!) it's not so great if you're consuming a half gallon of ice cream and trying to watch your weight at the same time. 11.1. List at least three types of lipids have you learned about. 11.2. What is a primary characteristic of all lipids? 11.3.
