Effect of Different Fatty Acid Types on Mitochondrial Dysfunction Associated With Brown and Beige Adipose Tissue

Adipose tissue serves as a dynamic endocrine organ that is pivotal in metabolic regulation. Augmenting mitochondrial activity within this tissue holds promise in combating obesity. Mitochondrial function is intricately modulated by diverse fatty acid compositions. This comprehensive review aimed to elucidate the molecular mechanisms underlying mitochondrial dysfunction induced by various fatty acid profiles. While saturated fatty acids (SFAs) pose a threat to mitochondrial integrity, polyunsaturated fatty acids (PUFAs), notably n-3, mitigate SFA-induced damage, concurrently regulating thermogenic gene expression. With regard to monounsaturated fatty acids (MUFAs), their impact on mitochondrial function in adipose tissue remains relatively unexplored. Although human studies are imperative for comprehensive insights, prioritizing the consumption of n-3 fatty acids and MUFAs has emerged as a strategic approach, potentially enhancing mitochondrial biogenesis and metabolic pathways. This synthesis underscores the critical need for further investigation of the differential effects of fatty acid types on adipose tissue mitochondria, offering potential avenues for obesity intervention.
