What is the equation for the hydrolysis of triglycerides?
Fats and oils are made up of triglycerides (triacylglycerols). Triglycerides contain 3 ester functional groups. Hydrolysis is a reaction with water. Acid hydrolysis of a triglyceride produces glycerol and fatty acids….Key Concepts.

What is the end product of triglyceride hydrolysis?
Hydrolysis of triglyceride into monoglyceride and free fatty acids is accomplished predominantly by pancreatic lipase. The activity of this enzyme is to clip the fatty acids at positions 1 and 3 of the triglyceride, leaving two free fatty acids and a 2-monoglyceride.
How are triglycerides formed reaction?
Triglycerides are formed by the condensation of one molecule of glycerol and three molecules of fatty acid. A condensation reaction between glycerol and a fatty acid (RCOOH) forms an ester bond. The R-group of a fatty acid may be saturated or unsaturated.
What are the chemical reaction of triglycerides?
A triglyceride is formed when the three hydroxyls (OH-) groups of a single glycerol molecule react with the carboxyl group (COOH-) of three fatty acids by forming ester bonds.
What is triglyceride hydrolysis?
Hydrolysis of triglycerides Triglycerides (fats) can be hydrolyzed to produce glycerol and 3 fatty acids in the presence of acid and heat or with a suitable lipase enzyme under biological conditions. When these fatty acids are neutralized with base they produce carboxylate ions which are used as soaps.
Why do we break down triglycerides?
Triglycerides cannot pass through cell membranes freely, and LPLs, special enzymes on the walls of blood vessels, must break triglycerides down into free fatty acids and glycerol; fatty acids can then be taken up by cells via fatty acid transporters.
How are triglycerides formed dehydration synthesis?
Triglycerides form via dehydration synthesis. Glycerol gives up hydrogen atoms from its hydroxyl groups at each bond, and the carboxyl group on each fatty acid chain gives up a hydroxyl group. A total of three water molecules are thereby released.
What is the formation of triglycerides called?
Triacylglycerols are formed by linking fatty acids with an ester linkage to three alcohol groups in glycerol. Triacylglycerols are the form in which fat energy is stored in adipose tissue. Triacylglycerols are sometimes referred to as triglycerides.
What are triglycerides write the synthesis?
The synthesis of a triglyceride is another application of the ester synthesis reaction. To write the structure of the triglyceride you must know the structure of glycerol and be given or look up the structure of the fatty acid in the table….Introduction.

How is triglyceride broken down?
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 is triglyceride synthesis?
Triglyceride synthesis Triglycerides are synthesized by esterification of fatty acids to glycerol. Fatty acid esterification takes place in the endoplasmic reticulum of cells by metabolic pathways in which acyl groups in fatty acyl-CoAs are transferred to the hydroxyl groups of glycerol-3-phosphate and diacylglycerol.
