INS and obesity due to melanocortin 4 receptor deficiency: While studies on the impact of BCFAs on ROS levels in the body are limited, Mika et al. [30] found that serum levels of C-reactive protein (CRP) and insulin were significantly and negatively correlated with levels of iso-BCFA (iso-C15:0, iso-C16:0, iso-C17:0, anteiso-C15:0, and anteiso-C17:0) in individuals with obesity compared to those without obesity.
