Sucrose, or table sugar with a chemical formula of C 12 H 22 O 11, is a common type of sugar made of glucose and fructose. Both sugars are then taken up by their specific transport mechanisms. 5. d) sucrose, lactose and maltose Sucrose is a disaccharide formed by glucose and fructose units joined by an acetal oxygen bridge from hemiacetal of glucose to the hemiketal of the fructose. It is broken down into many fields, reflecting the complexity of life from the atoms and molecules of biochemistry to the Biology Dictionary provides definition, examples and quiz for common biology terms, including molecular biology, cell biology, genetics, ecology and more! Sucrose is formed by plants, algae and cyanobacteria but not by other organisms. sucrose [soo´krōs] a disaccharide obtained from sugar cane, sugar beet, or other sources; used as a food and sweetening agent. Biology is the study of living things. Start studying AP Biology Ch. Sucrase is produced in the small intestine and aids in the digestion of sugar. c) lactose and maltose . Sucrose is the end product of photosynthesis and is found naturally in many food plants along with the monosaccharide fructose. The suffix -ase is used to signify an enzyme or identify a certain class of enzymes. In others, such as grapes and pears, fructose is the main sugar. It is a disaccharide , meaning that it is made up of two monosaccharide sugar units and a simple carbohydrate. sucrose in Biology topic From Longman Dictionary of Contemporary English sucrose su‧crose / ˈsuːkrəʊz, ˈsjuː- $ ˈsuːkroʊz / noun [ uncountable ] technical DF the most common form of sugar → fructose , lactose Examples from the Corpus sucrose • In the presence of each they received an infusion of a sucrose solution .

Sucrase (sucr-ase): This group of enzymes catalyzes the decomposition of sucrose to glucose and fructose. b) sucrose and maltose . When sucrose is consumed, the enzyme beta-fructosidase separates sucrose into its individual sugar units of glucose and fructose. n. A crystalline disaccharide of fructose and glucose, C12H22O11, extracted chiefly from sugarcane and sugar beets and commonly known as table sugar. Fruits and vegetables also naturally contain sucrose. Some disaccharides, such as sucrose, are nonreducing sugars, meaning they cannot donate electrons to other molecules. Sucrose occurs naturally in many foods and is often added to many processed foods to contribute sweetness. Dissachrides that are reducing in nature are: a) sucrose and lactose. Sucrose, or table sugar, organic compound, colourless sweet-tasting crystals that dissolve in water. Sucrose, or table sugar, is a common type of sugar made of glucose and fructose.
