Whey protein is made from byproducts of cheese making. It has a high bioavailability. I would say there is no just straight protein since there are many sources you can get it from. - Mike

Like Mike said...all protein is straight protein. Like beef is beef.
There are different sources of protein, such as dairy, egg, soya, etc. The best quality would be whey isolate.
