Basically what the title entails, are fats considered esters? Or? Bcos in my textbook it's written that there are saturated and unsaturated fats (with the alkene functional group), yet in another portion it is written that fats are naturally occurring esters, so I'm kinda confused! Thank you!

They are esters with or without double bonds in the long chains.

Esters always have a hydrocarbon chain anyway, which can be either single or double bonded.

They are triglyceride esters. Made from an alcohol (propane-1,2,3-triol or glycerol) and 3 long chains fatty acids. The fatty acids are just long chain carboxylic acids often with around 18 carbons. These can be saturated or unsaturated.
