Arachidonic acid is the keystone essential fatty acid at the origin of the arachidonic acid cascade. It is converted by cyclooxygenase, lipoxygenase, and epoxygenase enzymes into more than one hundred fifty different potent primary autacoid metabolites in species ranging from fungi to plants to mammals. Arachidonic acid is stored in tissue phospholipids in esterified form, where it comprises a small but critically controlled percentage of the polyunsaturated fatty acid pool.1 Arachidonic acid ethyl ester is a more lipophilic form of arachidonic acid that can be incorporated into dietary regimens or fed to cultured cells as a source of exogenous arachidonate. It is one of the fatty acid ethyl esters that increase cytosolic Ca2+ concentration leading to pancreatic acinar cell injury due to excessive consumption of ethanol.2 Whereas arachidonic acid inhibits dopamine uptake, the ethyl esterified version does not retain this property.3

Cayman Chemical Company regularly evaluates our shipping methods to ensure product stability is maintained and our corporate environmental impact is minimized. Products selected for review are evaluated and shipping methods are certified by our Scientists. While occasionally our method of shipping a product may change, rest assured the shipping conditions on all Cayman Chemical products have been reviewed and validated.
Upon receipt, it is important to check the storage requirements of your products and place them at the appropriate temperature. Products shipped without ice may require frozen storage for long term stability.
Cayman Chemical was formed over thirty years ago by demonstrating the value of naturally growing gorgonian corals as a renewable, economically viable source of prostaglandins. Today we operate our business knowing that we owe our start to the renewable resources our environment had provided. As Cayman Chemical continues to grow we consistently evaluate our business processes to ensure we are operating at the highest environmental standards.
