    Product Description

    Sterculic acid is a cyclopropene fatty acid that has been found in S. foetida.1 It is an inhibitor of Δ9-desaturase that decreases 9(Z)-myristoleic acid (Item No. 9002461) and increases oleic acid (Item No. 90260) and 9(Z),11(E)-conjugated linoleic acid (Item No. 90140) levels in the milk of lactating ewes when administered at a dose of 0.5 g per day.2 It also inhibits endoplasmic reticulum stress induced by 7-keto cholesterol (Item No. 16339) in ARPE-19 cells when used at a concentration of 1 µM and prevents the formation of choroidal neovascularization when applied to eyes at concentrations of 0.1 to 10 mM in a rat model of macular degeneration induced by laser injury.1 Sterculic acid binds to a variety of kinases, including calcium/calmodulin-dependent protein kinase kinase 2 (CAMKK2), mammalian sterile20-related kinase 3 (MST3), and p90 ribosomal S5 kinase 4 (RSK4).3 [Matreya, LLC.
