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...
As a result, the lactose is accompanied from the periplasm to the cytoplasm of the cell by an H+ proton. Lactose is a disaccharide carbohydrate found primarily in mammalian milk. The disaccharide consists of the monosacharides glucose and galactose. When the lactose is ingested and absorbed into the cell, the enzyme lactase breaks the disaccharide into its monosaccharide subunits. These are in turn used in the cellular respiration process and broken down further into energy for the cell. Lactose permease belongs to the family of so called Major Facilitators.
