What is the fat found in milk commonly known as?

The fat found in milk is commonly known as butterfat, which is the primary fat component in dairy products. Butterfat is responsible for the creamy texture and flavor of various milk products, including whole milk, cream, and butter. It is composed of a mixture of different types of fat globules and gives milk its characteristic richness.

The other options represent different dairy products or types of fat but do not correctly refer to the fat present in milk directly. Vegetable fat, for instance, refers to fats derived from plants and is not found in milk. Heavy cream is a dairy product that has a high fat content but is specifically the cream that rises to the top of milk when left to sit and is not synonymous with the fat itself. Cream cheese is a soft cheese made from milk and cream, featuring a blend of fat and protein but does not describe the fat found in milk.
