The accumulating literature demonstrates that omega-3 polyunsaturated fatty acid (n-3 polyunsaturated fatty acid, N3PUFA) can be incorporated into the phospholipid bilayer of cell membranes in the human body to positively affect the cardiovascular system, including improving epithelial function, decreasing coagulopathy, and attenuating uncontrolled inflammatory responses and oxidative stress. Moreover, it has been proven that the N3PUFAs, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are precursors of some potent endogenous bioactive lipid mediators that mediate some favorable effects attributed to their parent substances. A dose-response relationship between increased EPA and DHA intake and reduced thrombotic outcomes has been reported. The excellent safety profile of dietary N3PUFAs makes them a prospective adjuvant treatment for people exposed to a higher risk of cardiovascular problems associated with COVID-19. This review presented the potential mechanisms that might contribute to the beneficial effects of N3PUFA and the optimal form and dose applied.

Polyunsaturated fatty acids (PUFAs), fatty acids with multiple unsaturated carbon-carbon bonds, constitute a crucial class of lipids. While the vast diversity of PUFA species arises from their structural variations, most of them are poorly investigated due to their limited availability. Here, we utilize solid-phase synthesis of PUFAs, which we have recently developed, to construct a PUFA library.

Reactive oxygen species (ROS) are responsible for the oxidative truncation of polyunsaturated fatty acids (PUFAs). The products of these reactions have been implicated in many diseases such as cancer and atherosclerosis. As increasing attention is directed toward these oxidized phospholipids (oxPLs), higher throughput methods are needed to examine interactions between oxPLs and scavenger receptors in the immune system.

Ferroptosis, an iron-dependent cell death mechanism characterized by excessive lipid peroxidation, has been implicated in numerous human diseases and organ pathologies. However, current detection methods necessitate invasive tissue sampling to assess lipid peroxidation, making noninvasive detection of ferroptosis in human subjects extremely challenging. In this study, we employed oxidative volatolomics to comprehensively characterize the volatile oxidized lipids (VOLs) produced during ferroptosis.

Flaxseed oil contains elevated levels of omega-3 fatty acids (n-3 FA), which have been shown to impact reproductive performance. This study aimed to determine the effects of a flaxseed oil-based supplement on reproductive parameters, feeding behavior, and lipid profile in beef heifers. Sixty Angus and Simmental × Angus heifers (14 months old ± 2 months), blocked by full body weight (BW; 396.

Dietary n-6 and n-3 polyunsaturated fatty acid (PUFA) balance critically modulates various physiological processes, including inflammation and cell death. This study investigated the effects of different n-6 PUFA ratios (1:1, 5:1, 10:1, 20:1) on ferroptosis in porcine IPEC-J2 intestinal epithelial cells. Cells treated with varying PUFA ratios showed a significant reduction in cell viability, which was alleviated by the ferroptosis inhibitor ferrostatin-1 (fer-1).
