Fats ingested in the diet are digested in the small intestine. The triglycerides are broken down into monoglycerides and free fatty acids, then imported across the intestinal mucosa. Once across, the triglycerides are resynthesized and transported to the liver or adipose tissue.
How dietary fat is metabolized?
Digestion is the first step to lipid metabolism, and it is the process of breaking the triglycerides down into smaller monoglyceride units with the help of lipase enzymes. Digestion of fats begin in the mouth through chemical digestion by lingual lipase.
How fat is absorbed in the body?
The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fats, carbohydrates, and proteins. Your liver produces bile that helps you digest fats and certain vitamins.

When we metabolize fat during exercise where does it go?
Fatty acids are the most abundant source of endogenous energy substrate. They can be mobilized from peripheral adipose tissue and transported via the blood to active muscle. During higher intensity exercise, triglyceride within the muscle can also be hydrolyzed to release fatty acids for subsequent direct oxidation.
What is the role of liver in fat metabolism?
The liver plays a central role in all metabolic processes in the body. In fat metabolism the liver cells break down fats and produce energy. … If your blood sugar levels increase, for example after a meal, the liver removes sugar from blood supplied by the portal vein and stores it in the form of glycogen.

Where is excess fat stored?
If you’re carrying extra pounds, it means you’re taking in more energy (calories are units of energy) than you’re using. “The extra energy is stored in adipose tissue all around your body in the form of triglycerides,” says Dr. Burguera. Smaller amounts of energy are stored in your liver and muscles as glycogen.
Where does fat go when you lose weight?
The correct answer is that fat is converted to carbon dioxide and water. You exhale the carbon dioxide and the water mixes into your circulation until it’s lost as urine or sweat. If you lose 10kg of fat, precisely 8.4kg comes out through your lungs and the remaining 1.6kg turns into water.
What are the 2 major sources of fat used during exercise?
Fat and carbohydrate are the two major energy sources used during exercise. Either source can predominate, depending upon the duration and intensity of exercise, degree of prior physical conditioning, and the composition of the diet consumed in the days prior to a bout of exercise.
What is the most important factor in weight fat loss?
Portion control, or reducing the number of total calories, is really the most important factor for weight loss. The composition and quality of those calories are important for fat loss.
What is an advantage of fat as a source of fuel for exercise?
As a fuel, fat could be considered to have several advantages over carbohydrate, but from an exercise perspective it also has several disadvantages. It advantages are that it yields over twice as much energy as carbohydrate (9 kcal v 4 kcal) and that the body potentially has an abundant supply of it.
