Which Of The Following Contributes To The The Digestion Of Lipids?

What contributes to the digestion of lipids?


What enzymes are involved in lipid digestion?

They include gastric lipase, colipase-dependent pancreatic lipase, pancreatic lipase-related proteins 2 (PLRP2), carboxyl ester hydrolase or bile salt-stimulated lipase (CEH, BSSL), and pancreatic phospholipase A2.

Where does physical digestion of lipids begin?

Lipid digestion begins in the mouth, continues in the stomach, and ends in the small intestine. Enzymes involved in triacylglycerol digestion are called lipase (EC 3.1. 1.3).

What are the end products of lipid digestion?

The major products of lipid digestion – fatty acids and 2-monoglycerides – enter the enterocyte by simple diffusion across the plasma membrane. A considerable fraction of the fatty acids also enter the enterocyte via a specific fatty acid transporter protein in the membrane.

What are the 4 main digestive enzymes?


Which hormones are involved in lipid metabolism?

The principal hormones involved in lipid metabolism are insulin, glucagon, catecholamines, cortisol and growth hormone. The concentrations of these hormones are altered in chronic degenerative conditions such as diabetes and cardiovascular disease, which in turn leads to alterations in tissue lipids.

Which of the following is needed to digest lipids quizlet?

Bile is a fluid that contains important bile salts, needed for the breakdown of lipids in the small intestine. From the stomach, food passes into the duodenum, then the jejunum, and then the ileum.

What are the 2 types of digestion?


Where does lipid digestion begin quizlet?

Where does lipid digestion begin in the body? Lipid digestion occur in the mouth via lingual lipase, in the stomach via lingual lipase and gastric lipase, in the small intestine via pancreatic enzymes and bile salts. Finally absorption occurs in the jejunum.

What are some examples of chemical digestion?

Chemical digestion breaks down different nutrients, such as proteins, carbohydrates, and fats, into even smaller parts:

  • Fats break down into fatty acids and monoglycerides.
  • Nucleic acids break down into nucleotides.
  • Polysaccharides, or carbohydrate sugars, break down into monosaccharides.

How many different forms of lipids are commonly found in food?

The three main types of lipids are triacylglycerols (also known as triglycerides), phospholipids, and sterols. 1) Triglycerides make up more than 95 percent of lipids in the diet and are commonly found in fried foods, butter, milk, cheese, and some meats.
