Dihomo-γ-linolenic acid (DGLA) is one of the 20-carbon fatty acids that can be metabolized to prostaglandins and thromboxanes (TXs) by cyclooxygenases 1 and 2 (COX-1/COX-2).1 The result of this metabolism in the human platelet yields TXB1. TXB1 is produced in small amounts when DGLA is added to washed suspensions of human platelets, while the major metabolism of this 1-series fatty acid is via 12-lipoxygenase.2 However, when co-incubated with amounts of ethanol often found in intoxicated humans, the metabolism of DGLA shifts to an enhanced production of TXB1.2 Urinary TXB1 or its metabolites may thus be a specific biomarker of prior ethanol abuse.

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.
