As we all know fatty acids are an important component of lipids in animals, plants and micro organisms. At some point or the other you might need to calculate fatty acid of a sample. That's where you can use our Fatty Acids Calculator to find out the fatty acids of a sample. All you have to do is just provide the specific inputs as per the tool like volume of sodium hydroxide, normality of sodium hydroxide, equivalent factor, weight of sample and click on the calculate button and leave the rest for us. You will get the resultant Fatty Acid Percentage in no time.

Volume of sodium Hydroxide (V):
Normality of sodium hydroxide (N):

Fatty Acids - Definition

Fatty acids are nothing but the building blocks of fat that exists in our bodies as well as the food we eat. In general our body while undergoing the digestion process will break down the fats into fatty acids which later can absorbed by the blood. They are even classified into two types depending on the nature of covalent bond they share such as saturated and unsaturated fatty acids.

Classification of Fatty Acids

Fatty acids are divided into two major groups on basis of the bond existing between them

  • Saturated Fatty Acids
  • Unsaturated Fatty Acids

Saturated Fatty Acids: These are the fatty acids that don't have double bonds. Usually, Saturated Fatty Acids are long chain carboxylic acids that contain 12 to 24 carbon atoms but doesn't have double bonds. Examples for saturated fatty acids include palmitic acid, lauric acid, etc.

Unsaturated Fatty Acids: In case of unsaturated fatty acids there exists one or more double bonds between the carbon atoms. Some of the examples include monounsaturated fatty acid, omega fatty acids, polyunsaturated fat, etc.

Fatty Acid Percentage Formula

The formula to determine the free fatty acids percentage is given by the equation = (V*N*F/Weight of the Sample)

  • Where, V - Volume of sodium hydroxide
  • N - Normality of sodium hydroxide
  • F - Equivalent factor

How to find Fatty Acids Percentage?

Follow the below mentioned steps inorder to obtain the fatty acids percentage manually. They are as follows

  • Firstly, determine the values of Volume of Soidum Hydroxide(V), Normality of Sodium Hydroxide(N), Equivalent Factor(F), Weight of the Sample, etc.
  • Next step is to find the profuct of V, N and F
  • And then divide the product obtained with the Weight of the Sample to obtain the Fatty Acids Percentage.

Solved Examples on Fatty Acid Percentage

Calculate the estimated percentage of free fatty acid if Volume of Sodium Hydroxide = 30, Normality of sodium hydroxide is 15 and Equivalent factor is 20, Weight of sample is 10.


Volume of Sodium Hydroxide = 30

Normality of Sodium Hydroxide = 15

Equivalent Factor = 20

Weight of the Sample = 10

Apply the given values in the formula Fatty Acid Percentage = (V*N*F/Weight of the Sample)

= (30*15*20/10)

= 900

Therefore, Free Fatty Acid Percentage is 900.
