Ans :
The triglyceride molecule shown in the picture has saturated fatty acid chains. Usually the plant based cooking oils have double bonds in them , which make it unsaturated and less viscous then the animal fats that are highly saturated compounds.
Since here the molecule has all saturated fatty acids , it tends to have higher viscosity relatively.
Add Answer to:
