17-METHYLOCTADECANOIC ACID Usage And Synthesis

Description

17-methyl Stearic acid is a methyl branched-chain fatty acid that has been found in murine meibomian glands, C. cornucopioides mushrooms, and Phyllobacterium species. It has also been found in the aerial parts of C. ladanifer and its concentration exhibits seasonal variation.

Uses

17-Methylstearic acid is a methyl-branched fatty acid that has been found in mouse meibomian glands, C. cornucopioides mushrooms, and Phytobacter species. It is also found in the aerial parts of C. ladanifer, where its concentration varies seasonally.

Definition

ChEBI: A branched-chain saturated fatty acid that is octadecanoic (stearic) acid carrying a methyl substituent at position 17.
