What are two differences between carbohydrates and lipids?

Answer 1

Lipids can store more energy, don't dissolve in water and don't form polymers. Carbohydrates have less energy but are water soluble and can be polymers.

The body stores energy that it does not use as fat (lipids) because lipids have a greater capacity to store energy than carbohydrates. This makes sense when you consider that if you don't exercise enough, you will have excess energy and will therefore gain weight.

Because they contain less oxygen than carbon, lipids are hydrophobic molecules that do not dissolve in water. On the other hand, carbohydrates have a lot more oxygen than lipids and are hydrophillic, meaning they do dissolve in water.

It is also possible to argue that lipids lack the capacity to form long chains known as polymers, whereas carbohydrates do.

Lipids also consist of carbon, hydrogen, and oxygen, but in different proportions than carbohydrates. Carbohydrates are hydrophilic, whereas lipids are hydrophobic.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
