Triglycerides are the major type of lipid in milk fat. Triglycerides are composed of three fatty acids covalently bound to a glycerol molecule by ester bonds. Milk fat is the major source of lipid used by the neonate mammal for accumulating body adipose in the initial days after birth.
[EDIT ADDED] When the lactase enzyme is added to the milk, the lactose, a double sugar or disaccharide of glucose and galactose, is split. When you drink the treated milk, you can taste the glucose, which is why the milk is slightly sweeter. Nutritionally, the treated milk is unchanged from its original form.
