Natural Product Identification
Common Name11Z-Eicosenoic acid
Description11Z-Eicosenoic acid, also called eicosenoic acid C20:1, Is a monounsaturated fatty acid that exists in three different forms: 9-Eicosenoic acid (gadoleic acid), an omega-11 fatty acid common in fish oils, 11-eicosenoic acid (gondoic acid), an omega-9 fatty acid characteristic of jojoba oil, and 13-eicosenoic acid (paullinic acid), an omega-7 fatty acid. Also, eicosenoic acid C20:1 Is one of the fatty acids that have been identified in hemp (cannabis) seed oil (PMID: 28448475 ). 11Z-Eicosenoic acid is expected to be in Cannabis as all living plants are known to produce and metabolize it.
