Protein accounts for roughly 38% of the calories in mozzarella (part-skim), making it very protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Weight for weight, mozzarella (part-skim) has 1.5 g of protein for each gram of fat (24.3 g against 15.9 g per 100 g).
Set against fruit yogurt (lowfat), another dairy food entry in the database, a serving carries about 0.6 g less protein (fruit yogurt (lowfat) has 7.4 g per 1 container).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving quoted here is measured by weight at 28 g, and it covers about 14% of the 50 g FDA Daily Value for protein.
