This fish is mainly composed of saturated fatty acids (SFA: 57.36%) amount which, we can have myristic acid (C14:0), pentadecanoic acid (C15:0), palmitic acid (C16:0), heptadecanoic acid
(C17:0), stearic acid (C18:0) and arachidic acid (C20:0).
Each sample was then spiked with heptadecanoic acid
(0.5 mg/ml, 50 [micro]l).
was used as an internal standard.

Then the metabolite extraction procedure was carried out after adding two internal standard solutions (10 [micro]L of L-2-chlorophenylalanine in water, 0.3 mg/mL; 10 [micro]L of heptadecanoic acid
in methanol, 1 mg/mL) and 170 [micro]L of methanol.
Approximately 0.1 g of tree-borne seed oils were collected in test tubes, to which 0.5 mL heptadecanoic acid
(C17:0) (1 mg/mL hexane) was added as an internal reference.
A review of odd-chain fatty acid metabolism and the role of pentadecanoic acid (C15:0) and heptadecanoic acid
(C17:0) in health and disease.
(C17:0) varied between 0.85% and 2.52% in butter and 0.68% and 2.39% in ghee whereas arachidic acid (C20:0) was in the 0.32% to 0.98% range in butter and 0.21% to 0.90% range in ghee.
