41. Disaccharides include sucrose, lactose, and maltose; purified sucrose, for instance, is used as table sugar.42. Maltose is an oligosaccharide, specifically a disaccharide , formed by the union of two glucose units ( monosaccharide ). 43. Monosaccharides may be chemically bonded together to form disaccharides such as sucrose and longer polysaccharides such as starch and cellulose. 44. Sucrose is a disaccharide composed of glucose & fructose; maltose is a disaccharide composed of two molecules of glucose. 45. Sucrose is a disaccharide composed of glucose & fructose; maltose is a disaccharide composed of two molecules of glucose. 46. Trehalase is the enzyme responsible for the degradation of the disaccharide alpha, alpha-trehalose yielding two glucose subunits. 47. If the functional group is present in bonding with another sugar unit, it is called a reducing disaccharide or biose. 48. One of the first toxins to be expressed is tracheal cytotoxin, which is a disaccharide -tetrapeptide derived from peptidoglycan. 49. The systematic name of this enzyme class is "'ATP phosphohydrolase ( disaccharide -importing ) " '. 50. Carbohydrates may be classified as monosaccharides, disaccharides or polysaccharides depending on the number of monomer ( sugar ) units they contain.
