What distinguishes saturated fats from unsaturated fats?

Saturated fats are distinguished from unsaturated fats primarily by their chemical structure, specifically the presence or absence of double bonds in their fatty acid chains. Saturated fats contain only single bonds between carbon atoms, which allows them to be filled to capacity with hydrogen atoms. This structure leads to a higher melting point, making saturated fats solid at room temperature. In contrast, unsaturated fats have one or more double bonds in their fatty acid chains, which introduces kinks in their structure and prevents close packing of the molecules, resulting in a liquid state at room temperature.

While other statements may touch upon characteristics of saturated or unsaturated fats, they do not capture the fundamental chemical difference that defines their categorization.
