Sucrose cane sugar

Sources and Industrial Processes.—The industrial process of extracting and refining sucrose is most important. The sugar industry is one of the big industries of the world and a brief statement in regard to it will not be out of place. The amount of sucrose present in various plants may be given as follows . 

Pine apples, ii per cent I this is invert sugar. 

Only the first two of these sources are industrially important so far as obtaining the sugar in a commercial form is concerned. 

We shall follow the process as it is carried out with sugar beets though, in general, it is the same, or similar, when the sugar is obtained from the sugar cane. There are three general stages in the process. 

Concentration.—The next stage in the process is the purification and concentration of the juice and the crystallization of the sugar. The raw juice contains, as impurities, pectins, proteins and mineral salts. These are usually removed by the addition of lime at S °-go°, which causes the precipitation of the impurities. Care must be exercised however, or some sugar will also be precipitated in the form of calcium

Sucrose ( cane sugar, beet sugar ), melting point I7Q-186°C (decomposes). With the enzyme invertase, yields glucose plus fructose. Specific rotatory power +66,4°,... 

H.12 Energy is obtained in the body by a series of reactions which, overall, is equivalent to the combustion of sucrose (cane sugar), C12H22Ou, to carbon dioxide and liquid water. Write a balanced equation for its combustion. 

Sucrose, Cane Sugar or Saccharose, C12H22On.—Sucrose is very soluble in water from which it crystallises in large monoclinic prisms. It is sparingly soluble in alcohol. It is dextrorotatory, [a] °° = 66-5°... 

Sucrose (Cane Sugar, Beet sugar, Saccharose or (a-d-Glucosidoj-jS-d-fructofuranoside). 

There are many different types of sugar molecules. The type of sugar you use at home is called sucrose (cane sugar). Each sucrose molecule is made of atoms of carbon, hydrogen, and oxygen. When sugar molecules are heated to very high temperatures, each molecule... 

Sucrose (cane sugar) is a disaccharide in which the glycosidic link involves the anomer C-l of a-D-glucose and the anomeric C-2 of fructose. Sucrose (a-D-glucopyranosyl(l —> 2) (3-D-fruc.tofuranoside a-D-Glc(l —> 2) (3-D-Fru) does not have a reducing end because the reducing ends of both the constituent monosaccharides are involved in glycosidic bond formation (Section 4, Appendix).

Iron and silver are elements, and are made up of atoms. Sodium chloride (table salt) and sucrose (cane sugar), on the other hand, are compounds, and are made up of molecules. Nevertheless, the mole still works a mole of salt or sugar means 6.02 X 10 molecules of them. The molecular weights of salt and sugar are 58.45 and 342.3, respectively. Thus, 2.05 oz (58.45 g) of salt and 11.98 oz (342.3 g) of sugar contain the same number of molecules 6.02 X 10. ...

Give one qualitative and one quantitative statement about each of the following (a) water, (b) carbon, (c) iron, (d) hydrogen gas, (e) sucrose (cane sugar), (f) table salt (sodium chloride), (g) mercury, (h) gold, (i) air. 

Mannitol, sucrose (cane sugar) and glucose (corn sugar) are the best sugars used by the fungus for a carbon source. Mannitol maybe sterilized by autoclave. Sucrose and glucose should be Seitz filtered or they will produce lower levels of alkaloids. Sorbitol cuts alkaloid production in half and maltose drops alkaloid production to 1 /7 th that of mannitol.

Recall that proteins are also formed from smaller amino acid molecules by condensation reactions involving the loss of water molecules. Disaccharides include sucrose (cane sugar, used as a sweetener), lactose (milk sugar), and maltose (a product of the breakdown of starch). 

The French physicist Jean Baptiste Biot (1774-1862) then found that some liquids are optically active (that is, have the power of rotating the plane of polarization). For example, turpentine was found to be levorotatory, and an aqueous solution of sucrose (cane sugar, C12H22O11) was found to be dextrorotatory. The substances that were found to be optically active in solution were all organic compounds, produced by plants or animals.
