Every 100 kcal of soybean sprouts brings 10.5 g of protein. On that measure it ranks 13th of the 31 soy foods in this database and 240th of all 796 foods on the site. Measured by weight instead, its 8.47 g per 100 g ranks 22nd in its group.
Protein accounts for roughly 42% of the calories in soybean sprouts, 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, soybean sprouts has 1.9 g of protein for each gram of fat (8.47 g against 4.45 g per 100 g).
Set against meatless deli slices, another soy food entry in the database, a serving carries about 3 g more protein (meatless deli slices has 5 g per 1 slice).
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 volume at 94 g, and it covers about 16% of the 50 g FDA Daily Value for protein.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
8.47 g. The 1 cup cooked serving used on this page weighs 94 g and so carries 8 g.
How much protein do you get per 100 calories of soybean sprouts?
10.5 g. That figure divides its 8.47 g of protein per 100 g by its 81 kcal per 100 g, so it does not depend on serving size.
Is the protein in soybean sprouts complete?
Yes. The protein in soybean sprouts supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own.
What share of the protein Daily Value is one serving of soybean sprouts?
About 16%. One 1 cup cooked serving has 8 g, and the FDA Daily Value for protein is 50 g.
