This was a good video I watched the other day, where they tested protein content and go in to what protein actually is https://www.youtube.com/watch?v=tsOCD1gci60 (I 3rd-Party Tested The UK’s Top Protein Products).
Protein is made up of amino acids, different sources of protein have different amino acid profiles.
Animal protein matches the amino acids profile we need the best. Whey protein is close, soy isn't bad. You can vary your food groups to balance the amino acids, so if one source is low in one amino acid, you can compliment it with another source higher in another. I found the video intersting and been using protein supplements for near 20 years.
