Respiratory Quotient (RQ) value of tripalmitin is

Respiratory quotient value for tripalmitin is 0.7.
The chemical formula for tripalmitin is C₅₁H₉₈O₆.
The equation for aerobic breakdown of tripalmitin is

$2\left({\mathrm{C}}_{51}{\mathrm{H}}_{98}{\mathrm{O}}_6\right)+145{\mathrm{O}}_2\to 102{\mathrm{CO}}_2+98{\mathrm{H}}_2\mathrm{O}+\mathrm{Energy}.$

$\mathrm{R}.\mathrm{Q}=\frac{{\mathrm{CO}}_2}{{\mathrm{O}}_2}=\frac{102}{145}=0.7$

(1) 0.09 is not RQ for any respiratory substrate.

(2) When proteins are respiratory substrates, the ratio would be about 0.9.

(4) 0.07 is not RQ for any respiratory substrate.
