If you're converting from active dry to instant, you'll want to use about 75-80% of the yeast called for in the recipe. But I don't often bother, myself. The bread rises a bit faster than the recipe calls for, sometimes, but not much.
in digestion (biology): Digestion. The chemical reactions involved in digestion can be clarified by an account of the digestion of maltose sugar. Maltose is, technically, a double sugar, since it is composed of two molecules of the simple sugar glucose bonded together. The digestive enzyme maltase catalyzes a reaction in which a molecule of water is inserted at the point at which the two glucose units are linked, thereby...
One example of hydrolysis is the breakdown of starch, which is catalyzed by the enzyme amylase. Starch is broken down into smaller molecules, which consist of the sugar known as maltose. Maltose may then be further broken down into glucose molecules, under the influence of the enzyme maltase.
