Whats the difference between whey protein powder types?

I see different types with names approaching instantiated,isolate,gainer...what the difference with these?Thanks for the help.
Answers:
I dont know much more or less the terms instantised or ionized, as i just suggest they are terms used to market protein powders, and possibly they are just used to explain that they mix well and engage well into the blood stream.
whey protein isolate - is the most purest form of whey protein on the market, it have been isolated in it's extraction process, so it have very very minimal tubby and lactose, usually this form of whey protein is the best for repairing stressed muscle quickly. but it is also more expensive due to it high biological value(higher and purer protein). contains more next 90% protein.
whey protein concerntrate - a lower grade of whey protein, has some lactose and overweight still bound in the product, and is not as pure as wpi, these protein products contain about 20 - 89% protein.
Casein - this protein is the slowest react of all proteins, meaning it will drip into your blood stream and slowly brake down to be used over a longer term of time, it is the type of protein to be taken to suppress appetite or taken before bedtime to digest slowly over the night into your muscles. so it is not as hurried acting as the ones above. but can be used as said to slowly digest into the blood stream and eventually into the muscles.
Gainers/weight gainers - are usually a mix of whey protein isolate/concerntrate, and a carbohydrate powder, in which adds calories to your diet, so you are other in positive supply of nutrients to gain muscle or weight. some weightiness gainer powders may also have a supply of vitamins and minerials also. so this powder would be one to take to gain muscle and cargo. best wishes....
