"John is doing a paper on amylases- Amylases are enzymes formed when grain is malted. Amylases convert starch to sugars for the yeast to convert to alcohol. Amylase can be purchased to use on unmalted grains. Folks are interested in ways to use amylases.

I have a much better picture somewhere but i can't seem to locate the book. Amaylases are most effective at diferent temperatures. Deferent styles of mashes are designed to take advantage of these temperatures for various reasons. I prefer the compromise of a simple single temperature mashing. The other picture uses little cartoon characters to illustrate what each type of amalyse does to the starch molicules in order to make them easy for the yeast to convert."

"scotty,

Here's a few pictures that may be useful.

Starch is just a bunch of glucose (alpha-glucopyranose) molecules linked together via a(1,4) or a(1,6) bonds. The dashed lines represent a continuation of the chain. The a(1,6) bonds are where the branching occurs. An a(1,4) read ""alpha-one-four"" bond is between carbon #1 and carbon #4 ... and an a(1,6) bond is between carbon #1 and carbon #6. For starch, that's all there is to it.

[ATTACH=CONFIG]840[/ATTACH]

Here's an example of the structure when there's a bunch of branches (amylopectin).

[ATTACH=CONFIG]841[/ATTACH]

Those bonds are what we're trying to break when we use enzymes. Ideally, we're left with a bunch of glucose molecules for our yeast.
