In musical terminology, tempo (time in Italian; plural: tempi) is the speed or pace of a given piece. In classical music, tempo is usually indicated with an instruction at the start of a piece (often using conventional Italian terms). Tempo is usually measured in beats per minute (BPM).
Definition of polysaccharide. : a carbohydrate that can be decomposed by hydrolysis into two or more molecules of monosaccharides; especially : one (as cellulose, starch, or glycogen) containing many monosaccharide units and marked by complexity.
A disaccharide or biose is the carbohydrate which is formed when two monosaccharides (simple sugars) undergo a condensation reaction which involves the elimination of a small molecule, such as water, from the functional groups only. Like monosaccharides, disaccharides are soluble in water. Three common references are sucrose, lactose, and maltose. Disaccharide is one of the four chemical groupings of carbohydrates (monosaccharide, disaccharide, oligosaccharide, and polysaccharide). The most common types of disaccharidesâ sucrose, lactose, and maltose âhave twelve carbon atoms, with the general formula C 12 H 22 O 11.
