I do not like the way you reply questions!! I do not know anything at all but try to damn learn and damn frustrated with your bullies! But no choice as you are the one i need his advise. I read exactly what you wrote after first google i.e. "Gelatinize"! Thats why I oven baked barley which was a damn mistake!
I know Mark personally. He is definitely not a bully, as should be evident from the many posts he has, giving detailed information to so many questions. OK, some of his replies might be seen to be abrupt to some, but even a basic search about brewing generally will give answers to basic definitions of the brewing process. Just accept the way he responds, and learn from his wisdom!
Here's another link which should be helpful. This is the online 1st edition of this book, and the print version is now up to version 3+, but the basic information is still relevant. Definitely worth a read, and should answer most of your questions.
