For caloric purposes this makes no difference. Thus - again, soy protein = egg protein. Both will give you energy. Even with fairly low levels of food consumption (i.e. not average american), as long as it is varied, we get all the essential amino acids. Please note that even people on pretty intense weight loss diets don't suffer from "essential amino acid depletion" The bacteria in our gut can synthesize all the amino acids by the way, including essential ones, from pretty much any source of nutrients.
