Three types of PPARs have been identified: alpha, [[PPARG|gamma]], and delta (beta):<ref name="Berger_2002" />
* [[Peroxisome proliferator-activated receptor alpha|'''α''' (alpha)]] - expressed in [[liver]], [[kidney]], [[heart]], [[muscle]], [[adipose tissue]], and others<ref name="pmid22247890">{{cite journal |vauthors=Tyagi S, Gupta P, Saini AS, Kaushal C, Sharma S |title=The peroxisome proliferator-activated receptor: A family of nuclear receptors role in various diseases |journal=J Adv Pharm Technol Res |volume=2 |issue=4 |pages=236–40 |date=October 2011 |pmid=22247890 |pmc=3255347 |doi=10.4103/2231-4040.90879 |doi-access=free }}</ref>
* [[Peroxisome proliferator-activated receptor delta|'''β/δ''' (beta/delta)]] - expressed in many tissues, especially in [[brain]], [[adipose tissue]], and [[skin]]
* [[Peroxisome proliferator-activated receptor gamma|'''γ''' (gamma)]] - although transcribed by the same gene, this PPAR, by way of [[alternative splicing]], is expressed in three forms:
** γ1 - expressed in virtually all tissues, including [[heart]], [[muscle]], [[colon (anatomy)|colon]], [[kidney]], [[pancreas]], and [[spleen]]
** γ2 - expressed mainly in [[adipose tissue]]; it is 30 [[amino acid]]s longer than γ1
** γ3 - expressed in [[macrophage]]s, [[colon (anatomy)|large intestine]], [[white adipose tissue]]
