Unsaturated fats have less hydrogenâat least one of the carbons will have a hydrogen missing. Since there is no hydrogen for that carbon to bind to, the carbon atom forms a âdouble bondâ to a neighboring carbon atom instead. If a fat has one double bond, it is called âmonounsaturatedâ (missing one hydrogen).nsaturated fats have less hydrogenâat least one of the carbons will have a hydrogen missing.
