Source-derived summary

Auricolic acid is a linear fatty acid composed of 20 carbon atoms, with two double bonds at the position 11=12 and 17=18 and a hydroxyl-OH at the position 14. The compound's delta notation is 14-OH-20: 2Δ.

The acid is found in Lesquerella auriculata seed oil. Also, the compound has been isolated from Lesquerella ludoviciana, Lesquerella calcicola, Physaria saximontana and others from the genera Lesquerella and Physaria (Bladderpod oil).

Discovery

The acid was initially isolated in 1937 by researchers Kleiman, Spencer, Earle, Nieschlag, Barclay in the oil of Lesquerella auriculata and Lesquerella densiflora with the concentration of auricolic acid being between 30% and 40% of the total fatty acids.

Editorial summary

Begin with the source’s own compact description: “Auricolic acid” is fatty acid. The dossier treats that line as a proposition to test through Auricolic, acid and Fatty, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1937—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Auricolic, acid and Fatty is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “fatty acid” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 25, 2025. The linked authority identifier is Q53124145. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1937.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
