Fatty acids are molecules composed of a hydrocarbon chain with a carboxylic acid group ( - COOH) at one end. The smallest molecule that could be called a fatty acid is acetic acid (CH3COOH which is the acid in vinegar) in which the hydrocarbon chain is only on carbon long (a methyl group - CH3).
Fats are molecules composed of one to three (usually three) fatty acids bound by their carboxylic acid group to a glycerine molecule (see image above).

What two substances make up fats and oils?
Fats and oils are composed of glycerol and fatty acids. Glycerol serves as the backbone for triglycerides, which form the main structure of fats and oils, while fatty acids are the long hydrocarbon chains attached to the glycerol molecules.
Do molecules join to form fat in amino acids?
No, fat molecules are not formed by joining amino acids. Fats are made up of fatty acids and glycerol molecules, while amino acids are the building blocks of proteins. The process of joining fatty acids and glycerol forms a fat molecule through a process known as esterification.
Fats are absorbed into the villi in the form of what?
Fats are absorbed into the villi in the form of fatty acids and monoglycerides. These molecules are broken down by enzymes in the small intestine and then enter the villi for absorption into the bloodstream.
What cannot be form in fatty acids?
Fatty acids cannot form carbohydrates. Fatty acids are molecules composed of carbon, hydrogen, and oxygen, while carbohydrates are molecules composed of carbon, hydrogen, and oxygen in a different arrangement.
An alcohol that reacts with fatty acids to form fats?
Glycerol is an alcohol that can react with fatty acids through a process called esterification to form fats or triglycerides. This reaction forms ester bonds between the glycerol molecule and three fatty acid chains, resulting in the creation of a fat molecule.
What are the 2 monomers for fats?
The two monomers for fats are glycerol and fatty acids. Glycerol is a three-carbon alcohol, and fatty acids are long hydrocarbon chains with a carboxyl group at one end. When they combine through a condensation reaction, they form triglycerides, the primary form of fats in our bodies.
Do amino acid molecules join to form fats?
No. Amino acid molecules join together via peptide bonds to form peptides and proteins, not fats. Fats generally form from long chain fatty acids and glycerol.
Naturally occurring fats contain fatty acids in what formation?
Naturally occurring fats contain fatty acids in the form of triglycerides. Triglycerides consist of three fatty acid molecules linked to a glycerol molecule. This structure allows fats to store energy and be used as a fuel source by the body.
What two substances make up fats and oils?
Fats and oils are composed of glycerol and fatty acids. Glycerol serves as the backbone for triglycerides, which form the main structure of fats and oils, while fatty acids are the long hydrocarbon chains attached to the glycerol molecules.
Do molecules join to form fat in amino acids?
No, fat molecules are not formed by joining amino acids. Fats are made up of fatty acids and glycerol molecules, while amino acids are the building blocks of proteins. The process of joining fatty acids and glycerol forms a fat molecule through a process known as esterification.
What compounds form fat?
Fats are composed of molecules called triglycerides, which are made up of glycerol and three fatty acids. The fatty acids are chains of carbon atoms bonded together with hydrogen atoms attached. The types of fatty acids present in a fat molecule determine its characteristics.
What are the 2 types of building block molecules which are linked together by dehydration synthesis reactions to form neutral fats?
The two types of building block molecules that are linked together by dehydration synthesis to form neutral fats are glycerol and fatty acids. Glycerol is a three-carbon alcohol, while fatty acids consist of long hydrocarbon chains with a carboxylic acid group at one end.
What are the three molecules attached to glycerol molecules?
The three molecules attached to a glycerol molecule are fatty acids. These fatty acids form lipid molecules such as triglycerides, phospholipids, or waxes depending on the type and arrangement of the fatty acids bonded to the glycerol backbone.
Fats are absorbed into the villi in the form of what?
Fats are absorbed into the villi in the form of fatty acids and monoglycerides. These molecules are broken down by enzymes in the small intestine and then enter the villi for absorption into the bloodstream.
How many fatty acid molecules are needed to form a fat molecules?
3 fatty acids!
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 molecule are the fatty acids attached to?
Fatty acids are typically attached to glycerol molecules to form triglycerides or to other molecules to form phospholipids. In both cases, the fatty acids are attached through ester bonds.
