Explanation:
Detailed explanation-1: -Castor oil contains ricinoleic acid, a hydroxy monounsaturated fatty acid, as main constituent of its fatty acid profile. This acid is cis-12-hydroxy-9-octadecenoic acid and has an unusual polarity due to position of the hydroxyl group.
Detailed explanation-2: -Ricinoleic acid is the principal fatty acid in castor oil, whereas 12-hydroxystearic acid is the principal fatty acid in hydrogenated castor oil.
Detailed explanation-3: -Ricinoleic acid is perhaps the most interesting acid of all because of the oils, it is only found in castor oil. In fact, around 90% of castor oil is ricinoleic. None of the other oils contain it at all.
