ISSA Nutritionist Practice Exam

Which of the following is the correct number of carbons for a medium-chain fatty acid?

1. 4-10

2. 10-12

3. 6-8

4. 8-12

The correct answer is: 4-10

Medium-chain fatty acids, which are often used in various dietary and therapeutic contexts, are defined as fatty acids that contain a specific range of carbon atoms. The correct range for medium-chain fatty acids is typically between 6 to 12 carbon atoms. This definition makes it clear that fatty acids with 4 to 10 carbons do not fully meet the established criteria for medium-chain fatty acids, as they include shorter-chain fatty acids which are classified differently. The correct range for medium-chain fatty acids is therefore reflected in choices that suggest carbon counts starting from 6 to 8 and going up to 10 to 12, but primarily fall within the accepted classification of 6 to 12 carbons. Understanding the range is crucial for nutritional applications, especially in areas such as metabolism, weight management, and specific health dietary plans.
