Biological Activity
| ln Vivo |
Bovinic acid (10E,12Z-conjugated linoleic acid, 10E,12Z-CLA) was detected in human adipose tissue, and its levels were positively correlated with milk fat intake [1] In dairy cows, dietary modifications (e.g., adjusting forage-to-concentrate ratio, supplementing with vegetable oils) increased the content of Bovinic acid in milk fat, a fatty acid beneficial to human health [2] |

| Additional Infomation |
9-cis,11-trans-octadecadienoic acid is an octadeca-9,11-dienoic acid having 9-cis,11-trans-stereochemistry. It is a conjugate acid of a 9-cis,11-trans-octadecadienoate. Bovinic acid has been reported in Skeletonema marinoi with data available. Conjugated Linoleic Acid is a slightly altered form of linoleic acid, which is an omega-6 fatty acid important to human health. It is found in beef and dairy fats. Bovinic acid is a naturally occurring isomer of conjugated linoleic acid (CLA), primarily found in milk fat and dairy products [1][2] Literature [1] conducted an epidemiological study involving human subjects: adipose tissue samples were collected, and Bovinic acid concentrations were quantified by gas chromatography; dietary intake data were obtained via food frequency questionnaires, revealing a positive correlation between milk fat consumption and adipose tissue Bovinic acid levels [1] Literature [2] focused on modifying dairy cow diets to enhance beneficial fatty acids in milk fat: different dietary regimens were applied to cows, milk samples were collected, and Bovinic acid content was analyzed by lipid extraction and chromatographic methods; results showed that dietary adjustments effectively increased Bovinic acid levels in milk [2] |
Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~356.57 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (8.91 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 2: 20 mg/mL (71.31 mM) in 50% PEG300 50% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.  (Please use freshly prepared in vivo formulations for optimal results.) |
