The oil comprises of multiple components, including oleic acids, palmitic acid, stearic acid, and behenic acid, which add to its overall texture and wellness.

As shown in Table (4), tetracosanic acid (C24H48O2), behenic acid (C23H46O2), docosahexenoic acid (C22H40O2), ecosapentadecenoic acid (C20H30O2), hexadecanoic acid (C16H32O2) and dodecanoic acid (C12H24O2) were found at 0.524, 2.491, 6.633, 3.259, 1.496 and 0.038%, respectively in fraction 3, while they were not recognized in fraction 4.
BGS oil contained appreciable amounts of stearic acid (66.57%), oleic acid (9.76%) followed by palmitic acid (0.85%), linolenic acid (2.19%), arachidic acid and behenic acid (1.04% and 1.93%), respectively.
According to ANOVA analysis, the amount of [omega]-9 palmitoleic acid (C16:1[omega]-9), [omega]-7 and [omega]-11 oleic acids (C18:1[omega]-7, C18:1[omega]-11), behenic acid (C22:0), and lignoceric acid (C24:0) did not differ statistically among the samples (p > 0.05), whereas for all other fatty acids a statistical difference was found (p [less than or equal to] 0.05) for this set of samples.
The amount (%) of fatty acids in the crude oil are: myristic, 0.12; palmitic acid, 10.80; stearic acid, 0.24; arachidic acid, 1.17; behenic acid, 0.42; oleic acid, 47.40; linoleic acid, 26.36 and linolenic acid, 0.01.
Behenamide is an unsaturated long-chain carboxylic acid amide derived from behenic acid. Behenic acid is synthesized by hydrogenation of erucic acid, which is further reacted with ammonia to produce behenamide.
The receiver operating characteristic curves of 3D, 7D, and 11D-phytanic acid, behenic acid, and threoninyl-a-glutamate exhibited excellent efficiency with area under the curve (AUC) values of 0.904 (95% confidence interval [CI]: 0863-0.944), 0.93 (95% CI: 0.893-0.966), and 0.964 (95% CI: 00.941-0.988), respectively.

[11] have found that fatty acids with a longer alkyl chain adsorb preferentially on the graphite substrate by the investigation of binary mixtures of myristic acid ([C.sub.13][H.sub.27]COOH) and behenic acid ([C.sub.21][H.sub.43]COOH) using STM.
