The most common triglyceride component, with over half the mass, had (1) one linoleic and two linolenic acyls, or LNN or NLN using the codes of the table above.
There are smaller proportions of triglycerides with (4) one saturated, one linoleic, and one linolenic (XLN, LXN, etc.
[5] A more recent analysis (2009) of commercial oil found instead 80% (molar) of LLN, 14% PLN, 3% PPL, 1.5 RPL, and 0.5 SLN.
