Every 100 kcal of sharp cheddar cheese brings 5.9 g of protein. On that measure it ranks 49th of the 81 dairy foods in this database and 415th of all 796 foods on the site. Measured by weight instead, its 24.2 g per 100 g ranks 17th in its group.
Around 24% of the calories in sharp cheddar cheese come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
By weight, fat outweighs protein in sharp cheddar cheese: 33.8 g of fat per 100 g against 24.2 g of protein, a ratio of 0.7 to 1.
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 counted by piece at 28 g, and it covers about 14% of the 50 g FDA Daily Value for protein.
