Soy protein isolate is the more refined form of soy protein concentrate. This product has almost all of the carbohydrates, fiber and fats found in the original soy liquid removed, making it a very pure protein source for individuals with strict dietary goals. This protein is found in many vegan and vegetarian protein powders.
