Fats are hydrolised to fatty acids and glycerol by fat digestion which is aided by enzymes called lipases. Since fat molecules are large in size, a larger surface area needs to be provided; this occurs during emulsification in which bile, produced by the liver, is secreted, by the gall bladder, onto fat globules in the duodenum to emulsify fats into small droplets on which lipase can function in order to break-down the fats and produce glycerol and fatty acids. Hydrogen carbonate is secreted, as well, in order to neutralize the hydrochloric acid from the stomach; an almost-neutral pH (7.5) is optimal for the activity of lipases.
Fat is formed through a condensation reaction between glycerol and a fatty acid, where three fatty acids bond to the three hydroxyl groups of glycerol to form a triglyceride. This reaction also releases three molecules of water as a byproduct.
"Fat" Molecules are composed of 3 molecules of fatty acids and 1 molecule of glycerol bonded together by dehydration synthesis
An ester. The hydroxide on the glycerol reacts with the carboxylic acid of the fatty acid.
Mono, di and triglycerides are formed, depending on how many fatty acids combine with the glycerol.

What is a fat molecule made of?
A fat molecule is made of three fatty acid molecules attached to a glycerol molecule. The fatty acids provide energy storage and insulation, while glycerol serves as a backbone for the fatty acids to attach to.
What is the 3-carbon backbone of a fat?
The 3-carbon backbone of a fat is called glycerol. Glycerol is a key component of triglycerides, which are the most common type of fat in the body. It serves as a scaffold to which three fatty acid molecules can attach through ester linkages.
Which lipid will give a single molecule of fatty acid when hydrolyzed?
A triglyceride will give a single molecule of fatty acid when hydrolyzed through the process of lipolysis. Triglycerides consist of three fatty acid molecules attached to a glycerol molecule. Upon hydrolysis, one fatty acid is released along with glycerol.
How many fatty acid molecules are needed to form fat molecule?
It typically takes three fatty acid molecules to combine with a glycerol molecule in a process known as esterification to form a triglyceride, which is a type of fat molecule.
How many fatty acids is in a typical fat?
A typical fat molecule consists of three fatty acids attached to a glycerol backbone, forming a triglyceride.
What 2 types of molecules are needed to form a fat molecule?
To form a fat molecule, you need one glycerol molecule and three fatty acid molecules. These molecules combine through a process called dehydration synthesis to form a triglyceride, which is the basic structure of a fat molecule.
What is the end product of fat digestion?
The end products of fat digestion are fatty acids and glycerol.
During digestion fat is changed into?
Fatty acid molecules and glycerol
What are the sub unit that make up fat?
glycerol and fatty acid
What are components of fats?
Fats are composed of fatty acids, which are chains of carbon and hydrogen atoms. They also contain glycerol, a type of alcohol that connects the fatty acids together to form triglycerides. Different types of fats can vary in the length and saturation of their fatty acid chains.
What are the molecular units of fat molecules?
Fatty acid molecules and glycerol molecules.
What is a fat molecule made of?
A fat molecule is made of three fatty acid molecules attached to a glycerol molecule. The fatty acids provide energy storage and insulation, while glycerol serves as a backbone for the fatty acids to attach to.
What are the products of the acid catalyzed hydolysis of a fat?
Hydrolysis is the process of breaking down a compound with the action of water. The products of the acid catalyzed hydrolysis of a fat are fatty acids and glycerol.
What molecules are released when fat undergoes a hydrolysis reaction?
When fat undergoes a hydrolysis reaction, it is broken down into glycerol and fatty acids. Glycerol is a three-carbon alcohol, and fatty acids are long hydrocarbon chains with a carboxylic acid group at one end.
What is the end product of fat digestion called?
Simple sugar, amino acid, fatty acids, or fatty acids and glycerol
How are fat molecules formed?
Fat molecules are formed through a process called esterification, where a glycerol molecule combines with fatty acids. This bond forms a triglyceride molecule, which is the main type of fat found in our bodies and in food. Fat molecules can be stored in adipose tissue for energy reserves or used for various metabolic processes in the body.
What is each fat or oil made of?
It is made up of glycerol(alcohol) and fatty acid(carboxylic acid)
