RESUMO
Polyunsaturated omega-3 fatty acids (n-3 PUFA) are a family of essential fatty acids with many biological activities. These fatty acids are incorporated into cell membranes, changing their structural and functional characteristics. N-3 PUFA can act by modulating inflammatory responses at different levels. Omega-3 PUFA can be converted in the body to longer-chain n-3 PUFA at a limited rate and are differently converted in body systems. It appears that when specific longer-chain n-3 PUFA are desired these need to be supplemented directly in the diet. In different species some evidence indicates a potential effect on improving insulin sensitivity. Recently, a novel class of n-3 PUFA-derived anti-inflammatory mediators have been recognized, termed E-series and D-series resolvins, formed from EPA and DHA, respectively. N-3 PUFA derived resolvins and protectins are heavily involved in the resolution of inflammation. Supplementation with n-3 fatty acids in horses may help manage chronic inflammatory conditions such as osteoarthritis, equine metabolic syndrome, laminitis, and thereby help to improve longevity of sport horse.
