Unsaturated fat
Unsaturated fat are fats that contain at least one double carbon bond in its fatty acid chain that also tend to be liquid at room temperatureCite error: Invalid <ref> tag; name cannot be a simple integer. Use a descriptive title. This is due to their chemical structure, double bonds are stronger than single bonds and they are also shorter, this creates kinks in the structure of the fatty acid chain which disrupts the van der walls intermolecular forces between the fat moleculesCite error: Invalid <ref> tag; name cannot be a simple integer. Use a descriptive title. This causes the unsaturated fats melting point to decrease as less energy is needed to break the intermolecular forces, meaning the transition state between solid and liquid is at a lower temperature and it is liquid at room temperature compared to saturated fats.
