Define fatty acid?
In chemistry, especially biochemistry, a fatty acid is a carboxylic acid with a long aliphatic tail (chain), which is either saturated or unsaturated. Most naturally occurring fatty acids have a chain of an even number of carbon atoms, from 4 to 28. Fatty acids are usually derived from triglycerides orphospholipids. When they are not attached to other molecules, they are known as "free" fatty acids.
Formula for fat?
Depends which fat, there are many different compounds that are considered fatty acids. All contain an even number of carbons and a carboxyllic acid terminus. There are also 3 categories for these fats, saturated fatty acids, MUFAs (mono-unsaturated fatty acids), and PUFAs (poly-unsaturated fatty acids). A small 16-chain fatty acid which is completely saturated would look like this: CH3(CH2)14COOH Or C16H32O2
What is the chemical composition of fats?
Fatty acids and glycerol
What does the hydrolysis of a neutral fat result in?
glycerol and three fatty acids
What is the difference between a saturated and ' unsaturated fatty acid?
Saturated fatty acids have no double covalent bonds between carbon atoms. The carbon in the chain is saturated with all the hydrogens it can hold. Saturated fatty acids account for the solid nature at room temperature of fats such as lard and butter. Unsaturated fatty acids have double bonds between carbon atoms wherever the number of hydrogens is less than two per carbon atom. Unsaturated fatty acids account for the liquid nature of vegetable oils at room temperature.
Glycerol and fatty acids are found in what type molecule?
Unreacted fatty acids are rare in nature, but most fats and oils are triglycerides of fatty acids, and the acids can be recovered by hydrolyzing the triglycerides. This process is sometimes called "saponification" when the hydrolysis is aided by strong alkali, as in that instance the primary products (aside from glycerin) are salts of fatty acids, which are often good soaps.
How many types of fatty acids are found in human body?
There are two main types of fatty acids found in the human body: saturated fatty acids and unsaturated fatty acids. Unsaturated fatty acids can be further classified into monounsaturated and polyunsaturated fatty acids.
Distinguish between saturated fatty acids and saturated fatty acids?
There is no difference between saturated fatty acids and saturated fatty acids. If you meant saturated fatty acids and UNsaturated fatty acids, then the unsaturated ones are the ones with double (or, theoretically, triple) bonds in the carbon chain.
What functional group is responsible for the acidic properties of fatty acids?
The carboxyl group (-COOH) is responsible for the acidic properties of fatty acids. This group can donate a proton (H+) when in solution, leading to the release of hydrogen ions and contributing to the acidic nature of fatty acids.
What are unsaturated fatty acids?
Unsaturated fatty acids are fatty acids that have double bonds in their long carbon chains.
Unsaturated fatty acids that have changed to saturated fatty acids are called?
Hydrogenated fatty acids.
Are fatty acids polar or nonpolar?
Fatty acids are nonpolar.
What are the two essential fatty acids are?
Mono and polyunsaturated fatty acids.
Does triglyceride contain branched chains?
Triglycerides are composed of a glycerol molecule bonded to three fatty acids through ester linkages. The fatty acids can have branched chains, such as in the case of certain types of saturated fats found in nature. However, triglycerides typically contain predominantly straight-chain fatty acids.
Why is beef fat a solid at room temperature?
This is because it contains more saturated fatty acids then unsaturated fatty acids. Saturated fatty acids have a higher melting point then unsaturated fatty acids.
What is the difference between fatty acids and fats?
Fatty acids are the building blocks of fats. Fats are made up of a combination of different fatty acids. Fatty acids are the individual molecules that make up fats.
