PPAR-beta, or Peroxisome Proliferator-Activated Receptor Beta, is a type of protein that plays a crucial role in regulating fat metabolism and energy balance in the body. It is part of a larger family of receptors known as PPARs, which help control how cells respond to fatty acids and other nutrients. This receptor is found in various tissues, including the liver, muscle, and brain, and is involved in processes like inflammation and cell differentiation. Research suggests that PPAR-beta may have potential benefits for conditions such as obesity, diabetes, and cardiovascular diseases by improving lipid profiles and enhancing insulin sensitivity.
