Respiratory Quotient (RQ) is the ratio of the volume of carbon dioxide produced to the volume of oxygen consumed in respiration over a period of time.

RQ=Volume of CO2 evolvedVolume of O2 absorbed; RQ for fats is about 0.7

Tripalmitin = C51H98O6

2(C51H98O6)+145 O2102 CO2+98 H2O

RQ=102 CO2145 O2=0.7
