Fats and Oils The more viscous a substance is, the more saturated fats they have, and the less saturated.
Viscosity is a measure of how well a substance flows.
Mono saturates have one double bond
Poly saturates have more than one double bond
These fats are straight - this means they line up well so there is more friction between the molecules - so they are viscous or solid. Mono unsaturated fats
These fats contain a bend - this means they don't like up well so there is less friction between the molecules so they are not viscous or a liquid.
