Biological Activity

Additional Infomation

Elaidic acid is a 9-octadecenoic acid and the trans-isomer of oleic acid. It has a role as a food component. It is a conjugate acid of an elaidate and an Octadec-9-enoic acid anion. It derives from a hydride of a trans-octadec-9-ene. Elaidic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Elaidic Acid has been reported in Punica granatum, Cynomorium songaricum, and other organisms with data available. See also: Oleic Acid (subclass of).

Solubility Data

Solubility (In Vitro)

DMSO : ~13.5 mg/mL (~47.79 mM)

Solubility (In Vivo)

Solubility in Formulation 1: ≥ 1.35 mg/mL (4.78 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 13.5 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.)

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	3.5403 mL	17.7016 mL	35.4032 mL
	5 mM	0.7081 mL	3.5403 mL	7.0806 mL
	10 mM	0.3540 mL	1.7702 mL	3.5403 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
