α-Linolenic acid-d
5 (ALA-d
5) is intended for use as an internal standard for the quantification of ALA by GC- or LC-MS. α-Linolenic acid is an essential ω-3 polyunsaturated fatty acid found in plants.
1 In vivo, it is converted to the longer-chain fatty acids eicosapentaenoic , docosapentaenoic , and docosahexaenoic acid .
2 It is also catabolized
via fatty acid β-oxidation for energy or the synthesis of saturated and monounsaturated fatty acids, or stored in adipose tissue. Dietary consumption of ALA-containing foods is positively associated with a moderately lower risk of cardiovascular disease.

ALA-d
5 MaxSpec
? standard is a quantitative grade standard of ALA-d
5 that has been prepared specifically for mass spectrometry and related applications where quantitative reproducibility is required. The solution has been prepared gravimetrically and is supplied in a deactivated glass ampule sealed under argon. The concentration was verified by comparison to an independently prepared calibration standard. This ALA-d
5 MaxSpec
? standard is guaranteed to meet identity, purity, stability, and concentration specifications and is provided with a batch-specific certificate of analysis. Ongoing stability testing is performed to ensure the concentration remains accurate throughout the shelf life of the product.
