No. Fatty acids become esterified after interaction with an alcohol.
Essentially, there is no difference. Some prefer to use the term non-esterified fatty acid (NEFA) compared with free fatty acid (FFA) because many find the term FFA confusing with respect to fatty acids that circulate within the bloodstream which are 'bound' to albumin, but not esterified to another chemical moiety compared with intracellular fatty acids that are not 'bound' to albumin which are also not esterified to another chemical moiety.
Biodiesel is composed of Fatty Acids with Methyl, Propyl or Ethyl Esters. Some common forms of biodiesel are Methyl Linoleate and Ethyl Stearate. ==Methyl Linoleate== Chemical Formula: C19H34O2 ==Ethyl Stearate== Chemical Formula: C20H40O2

It is necessary to give the name of this compound for an answer.
Biodisel is obtained from vegetal or animal fats by transformation in fatty acids esters.
what is the process called that adds tree glycerol to 3 fatty acids? Glycerol is a sugar alcohol containing three hydrophillic hydroxyl groups. When these three OH groups are esterified with three fatty acids, the product is a triglyceride.
Biodiesel does not have a regular molecular formula because it is a mixture of different molecules. It is prepared from the esterification of fatty acids with methanol, and a typical fatty acid is stearic acid, CH3(CH2)16COOH. The ester would therefore be CH3(CH2)16COOCH3, or C19H39O2.
These molecules are highly hydrophobic because the long chains of fatty acids esterified to a glycerol molecule. They are the most important lipids in plasma membrane that form the so-called lipid bilayer. When the fatty acids present in triacylglycerols are saturated, they become a strong water repelent to the cell. When these fatty acids have one or more unsaturated bonds, they turn to be more akin or water tolerant. While the unsaturated bonds are more present in fatty acids, the more water tolerant they will be.
Fatty acids and glycerol
Fat is actually not a compound, it is a mixture of many esterified acids called 'fatty acids'. But it is basically a triglyceride, a triester of Glycerol (C3H5(OH)3) with fatty acids (R):CH2ORCHOR'CH2ORThe symbol R represents 'aliphatic carboxyl groups' with linear, even numbered, alkane chains.General formula -C(O)-(CH2)2n-CH3 with n=0,1,2,3....Some examples of possible fatty acids (esterified, all very common in fat)Stearate (from stearic acid): -C(O)-(CH2)16-CH3 with n=8, so 'octadecanoate'
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.
