What is fatty part of milk called?

The fatty part of milk is commonly referred to as cream or milk fat. Cream rises naturally to the top of unhomogenized milk due to its lower density compared to the other components of milk. It can also be separated from the milk through skimming, centrifugation, or other methods of dairy processing. Cream contains a higher concentration of fat than whole milk and is often used in various dairy products, such as butter, cheese, sour cream, and ice cream.
