What reaction occurs to form a triglyceride?
When a molecule of one glycerol molecule and three fatty acid molecules (R-COOH) join together, a condensation reaction takes place (ester bond formation) where three water molecules are removed and a basic lipid is formed which is called triglyceride.
How a triglyceride is formed via the condensation reaction?
Triglycerides are formed when condensation reactions occur between one glycerol and three fatty acids. Triglycerides can be either saturated or unsaturated, depending on the composition of the fatty acid chains.
What reactions break down triglycerides?
Triglycerides can be broken down through a reaction involving the pancreatic lipase enzyme responsible for hydrolyzing the ester bonds and allowing the fatty acids to be released from the glycerol molecule.
Do Lipids form through condensation?
Condensation is a chemical process by which 2 molecules are joined together to make a larger, more complex, molecule, with the loss of water. It is the basis for the synthesis of all the important biological macromolecules (carbohydrates, proteins, lipids, nucleic acids) from their simpler sub-units.
Do triglycerides release water during hydrolysis?
The hydrolysis reaction is reversible. It is called a condensation reaction because it produces water as a side product. The hydrolysis of a triglyceride is one of the oldest examples of a hydrolysis reaction, as it has been used for centuries to make soap. The reaction is called saponification.
Which reaction produces a solid triacylglycerol from a liquid triacylglycerol?
During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides. Triacylglycerols: Triacylglycerol is formed by the joining of three fatty acids to a glycerol backbone in a dehydration reaction.
Are triglycerides hydrophobic or hydrophilic?
Triglycerides comprise three fatty acids bonded to glycerol, yielding a hydrophobic molecule.
Are triglycerides polar or nonpolar?
Triglycerides are non-polar, and should dissolve immediately in our non-polar solvent.
How do you 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.
Are triglycerides soluble in water?
Triglycerides are completely insoluble in water. However, due to the ionic organic phosphate group, phospholipids demonstrate properties because the ionic group is attracted to water. Phospholipids have both a polar, hydrophilic end, and a nonpolar, hydrophobic end.
What’s the condensation reaction for carbohydrates?
A condensation reaction takes place releasing water. This process requires energy. A glycosidic bond forms and holds the two monosaccharide units together. The three most important disaccharides are sucrose, lactose and maltose.
What is the condensation reaction between glycerol and phospholipid?
Triglycerides and phospholipids are two groups of lipids A condensation reaction (removal of water) between a glycerol molecule and fatty acid forms an ester bond
What happens when glycerol and triglyceride are combined?
Each fatty acid is joined and combined with the glycerol forming an ester bond in three condensation reaction. Hydrolysis causes the breakdown of the triglyceride and produces glycerol and three fatty acids. These are the esters of fatty acids with alcohol (with higher molecular weight) other than glycerol.
What happens when a triglyceride is heated with soap?
When agitated with water in the presence of soap they form emulsions It takes place by heating a triglyceride with water at higher temperature and pressure in the presence of an enzyme called lipase which results in the formation of fatty acid and glycerol.
Why does a glyceryl tristearate dissolve in water?
The compound (glyceryl tristearate – C57H110O6!) which is created afterwards, is also referred to as a trigylceride. The molecule acquires many carbon atoms which are linked to hydrogen atoms; in the form of hydrocarbons and not in the form of -OH groups. It is due to THIS that fats don’t dissolve in water.
