Question

True or False for all

1. Saturated fatty acids contain one or more double bonds between carbons, reducing the number of hydrogen atoms that can be bound to the structure

2. The triglycerides found in food contain a combination of saturated, monounsaturated, and polyunsaturated fatty acids

3. Triglycerides must be broken down into smaller components for absorption; after they are absorbed, they are resynthesized back into triglycerides to be transported around the body

4. A chylomicron contains diet-derived triglycerides and is absorbed directly into the bloodstream from the small intestine.

5. B-oxidation is the process of cleaving a fatty acid into two carbon segments and converting them to acetyl-CoA.

6. Ketone bodies can be produced as a result of fat metabolism, and an overreliance on fat metabolism can result in ketosis, which has been shown to be beneficial for optimal athletic performance.

7. During prolonged steady-state exercise (as with marathon running), there is a reduced reliance on carbohydrate and an increased dependence on fat oxidation for energy.

8. The percentage of energy derived from fat metabolism increases as activity and exercise intensity increases

9. Caffeine may increase the mobilization of fatty acids during exercise, but it does NOT appear to improve performance due to increased fat metabolism.

10. The daily recommendation of fat is independent of the other macronutrients and total energy

11. If done correctly, a reduction in dietary fat intake can be a strategy that results in the safe loss of body fat

12. Olives, sesame seeds, and flax seeds all contain fat

13. The typical American diet is usually too high in fat for an athlete in training

14. Both caffeine and carnitine supplementation have been shown to be effective for improving endurance performance and high-intensity activities lasting up to 20 minutes.

15. Omega-3 fatty acid supplements have been shown to reduce inflammation in athletes.

Answer 1

1. Saturated fatty acids contain one or more double bonds between carbons, reducing the number of hydrogen atoms that can be bound to the structure. (False)

The saturated fatty acid binds with the Hydrogen atoms. The fact is more numbers of hydrogen atoms a fatty acid has, the more saturated it is.

2. The triglycerides found in food contain a combination of saturated, monounsaturated, and polyunsaturated fatty acids. (True)

Triglycerides are the types of fat found in the blood. it is from fats like saturated, monounsaturated, and polyunsaturated fatty acids. Almost all types of fat found in food contribute to triglycerides.

3. Triglycerides must be broken down into smaller components for absorption; after they are absorbed, they are resynthesized back into triglycerides to be transported around the body. (True)

Triglycerides are break down in the process called emulsification to monoglyceride and fatty acids.

4. A chylomicron contains diet-derived triglycerides and is absorbed directly into the bloodstream from the small intestine. (True)

chylomicron is a component of blood and lymph, It is a lipoprotein which consists of cholesterol, triglycerides, phospholipids, protein, and phospholipids.
