Answer: Single covalent bond in the long hydrocarbon chain.
Saturated fatty acids are long chains of hydrocarbon ( with single covalent bond) ending with the carboxylic group (-COOH).

Answer:
A. Proteins, Carbohydrates, or fats
Explanation:

The main nutrients we use for energy are carbohydrates, fats, and proteins. This is because they contain calories in them and the calories are what our body needs to create energy.
Our bodies, like a car, need fuel to function. The fuel we need comes from food. The food has energy stored in it so whenever we eat food, that stored energy is transferred to us. This food act as fuel for the cells in our body so they can carry all the metabolic processes and give us the energy to move, run, think, talk, digest and all of the biological processes we need to survive.
