Final answer:
The major fates of amino acids in the body include conversion to energy or glucose, incorporation into proteins, and storage as fat.
Step-by-step explanation:
The major fates of amino acids in the body include:
- Conversion to energy or glucose
- Incorporation into proteins
- Storage as fat
Amino acids can be broken down into energy for the body, stored as triglycerides for later use, or converted into acetyl CoA. These processes ensure that amino acids can serve as a metabolic fuel source when needed. However, it is important to note that excess amino acids cannot be stored like carbohydrates or fats, so they must be converted into glucose or triglycerides to meet the body's energy needs.
