Which Of The Following Is A True Statement Regarding Triglyceride Digestion?

Which of the following is a true statement regarding triglyceride digestion quizlet?

Which of the following is a true statement regarding triglyceride digestion? Triglycerides are digested into free fatty acids and monoglycerides by pancreatic lipase.

What happens when triglycerides are digested?

After ingested triglycerides pass through the stomach and into the small intestine, detergents called bile salts are secreted by the liver via the gall bladder and disperse the fat as micelles. Pancreatic enzymes called lipases then hydrolyze the dispersed fats to give monoglycerides and free fatty acids.

What is true regarding triglycerides?

When you consume — or your body creates — excess triglycerides, they’ re stored in fat cells for later use. When they’re needed, your body releases them as fatty acids, which fuel body movement, create heat and provide energy for body processes. For good health, your triglyceride level should be less than 150 mg/dL.

What is essential in the digestion of triglycerides?

Once triglycerides are emulsified, then triglycerides can be enzymatically digested in the small intestine. Enzymes that are made by the pancreas and small intestine are lipase enzymes. These enzymes act to split fatty acids from glycerol leaving glycerol, fatty acids, and monoglycerides to be absorbed.

Which of the following is a risk factor for cardiovascular disease quizlet?

Smoking; smoking, hypertension, and high cholesterol are major risk factors for cardiovascular disease.

Which food combination does not contain cholesterol quizlet?

Which food combination does NOT contain cholesterol? E. peanut butter and jelly sandwich.

What enzyme digests triglycerides?

Lipases hydrolyze triglycerides (fats) into their component fatty acid and glycerol molecules. Initial lipase digestion occurs in the lumen (interior) of the small intestine.

What are the steps of lipid digestion?

The digestion of certain fats begins in the mouth, where short-chain lipids break down into diglycerides because of lingual lipase. The fat present in the small intestine stimulates the release of lipase from the pancreas, and bile from the liver enables the breakdown of fats into fatty acids.

How are triglycerides broken down in the body?

Lipolysis. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl CoA, which is used by the Krebs cycle

What are 3 functions of triglycerides?

Triglycerides and cholesterol are different types of lipids that circulate in your blood:

  • Triglycerides store unused calories and provide your body with energy.
  • Cholesterol is used to build cells and certain hormones.

What are the 3 types of triglycerides?

The three types of fatty acids that compose triglycerides are saturated, monounsaturated and polyunsaturated fatty acids.

What is the source of triglycerides?

Triglycerides are fats from the food we eat that are carried in the blood. Most of the fats we eat, including butter, margarines, and oils, are in triglyceride form. Excess calories, alcohol or sugar in the body turn into triglycerides and are stored in fat cells throughout the body.

Where does chemical digestion of triglycerides begin?

The first step in the digestion of triglycerides and phospholipids begins in the mouth as lipids encounter saliva. Next, the physical action of chewing coupled with the action of emulsifiers enables the digestive enzymes to do their tasks.

What enzyme digests cholesterol?

Cholesterol esterase (CE) (bile salt-stimulated esterase or carboxyl ester lipase) primarily hydrolyzes cholesterol esters. It is synthesized in the pancreas and is released in response to CCK in a fully active form.

What are the typical end products of triglyceride digestion quizlet?

1) Glycerol, monoglycerides, and fatty acids are absorbed from the lumen of the small intestine into the small intestinal cells. 2) Triglycerides are reassembled within the cells lining the small intestine. 3) Triglycerides are packaged into chylomicrons.
