Which type of fats have all carbon's bonds filled or occupied by hydrogen atoms?

Saturated fats are characterized by their chemical structure, where all the carbon atoms in the fatty acid chains are fully bonded to hydrogen atoms. This means there are no double bonds between carbon atoms in the chain, making them "saturated" with hydrogen. This full occupation of bonds lends saturated fats their typically solid state at room temperature and is a common feature in animal fats, as well as certain plant oils, like coconut oil and palm oil.

In contrast, unsaturated fats, which includes both monounsaturated and polyunsaturated fats, have one or more double bonds between carbon atoms, resulting in fewer hydrogen atoms attached to the carbons. This absence of hydrogen results in a less saturated fat structure, often leading to a liquid state at room temperature. Trans fats, a type of unsaturated fat, have been chemically altered to remain solid or semi-solid, but they still contain double bonds that make them different from saturated fats.
