Linseed oil is a [[triglyceride]], like other fats. Linseed oil is distinctive for its unusually large amount of [[alpha-linolenic acid|α-linolenic acid]], which oxidises in air. The fatty acids in a typical linseed oil are of the following types:<ref name=vereshagin>{{cite journal |doi=10.1007/BF02632457 |pmid=5898097 |title=The triglyceride composition of linseed oil |year=1965 |last1=Vereshchagin |first1=A.

*The triply unsaturated α-linolenic acid (51.9–55.2%),
*The saturated acids [[palmitic acid]] (about 7%) and [[stearic acid]] (3.4–4.6%),
*The monounsaturated [[oleic acid]] (18.5–22.6%),
*The doubly unsaturated [[linoleic acid]] (14.2–17%).
