Biosynthesis of polyunsaturated fatty acids in lower eukaryotes (original) (raw)

Polyunsaturated fatty acids (PUFAs) play a crucial role in the structural integrity of cell membranes and serve as precursors for bioactive molecules such as eicosanoids. The biosynthesis of PUFAs occurs via two primary pathways identified in lower eukaryotes, particularly fungi and marine microalgae, highlighting the enzymatic variability and potential for biotechnological applications in producing nutraceutic oils. The study provides an overview of desaturases, which are essential enzymes in PUFA synthesis, and discusses their classification and function in different organisms.
