2091-26-1 Usage
General Description
"(8E,11E,14E,17E)-icosa-8,11,14,17-tetraenoic acid" is a long-chain polyunsaturated fatty acid. It contains four double bonds, which give it a flexible and fluid structure, making it an important component of cell membranes. This acid is also a precursor to eicosanoids, which are signaling molecules that play important roles in inflammation and immune response. It is found in abundance in fish and seafood, and is known to have cardiovascular benefits such as reducing the risk of heart disease and improving cholesterol levels. It also has anti-inflammatory properties and may have a role in maintaining healthy brain function. Overall, "(8E,11E,14E,17E)-icosa-8,11,14,17-tetraenoic acid" is an important and beneficial fatty acid with a variety of physiological functions.
Check Digit Verification of cas no
The CAS Registry Mumber 2091-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,9 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2091-26:
(6*2)+(5*0)+(4*9)+(3*1)+(2*2)+(1*6)=61
61 % 10 = 1
So 2091-26-1 is a valid CAS Registry Number.

Substrate specificity and regioselectivity of Δ12 and ω3 fatty acid desaturases from Saccharomyces kluyveri
Oura, Takahiro,Kajiwara, Susumu
experimental part, p. 3174 - 3179 (2009/04/07)
Δ12 and ω3 fatty acid desaturases are key enzymes in the synthesis of polyunsaturated fatty acids (PUFAs), which are important constituents of membrane glycerolipids and also precursors to signaling molecules in many organisms. In this study, we determined the substrate specificity and regioselectivity of the Δ12 and ω3 fatty acid desaturases from Saccharomyces kluyveri (Sk-FAD2 and Sk-FAD3). Based on heterologous expression in Saccharomyces cerevisiae, it was found that Sk-FAD2 converted C16-20 monounsaturated fatty acids to diunsaturated fatty acids by the introduction of a second double bond at the ν + 3 position, while Sk-FAD3 recognized the ω3 position of C18 and C20. Furthermore, fatty acid analysis of major phospholipids suggested that Sk-FAD2 and Sk-FAD3 have no strong substrate specificity toward the lipid polar head group or the sn-positions of fatty acyl groups in phospholipids.
