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...
Dietary lactose and sucrose are ready for digestion by their respective brush border enzymes. Starch, as discussed previously, is first digested to maltose by amylase in pancreatic secretions and, in some species, saliva. glucose generated by digestion of starch or lactose is absorbed in the small intestine only by cotransport with sodium, a fact that has exceptionally important implications in medicine.
