Glucose plants

Carbohydrates Ultimately, carbohydrates cire the product of photosynthesis, the process in plants that combines carbon dioxide, water, and energy with chlorophyll and other biomolecules to produce Ccirbohy-drates and release oxygen gas. The major carbohydrate formed during photosynthesis is glucose. Plants and animals sometimes combine simple carbohydrates such as glucose into more complicated carbohydrates such as stcirch, glycogen, and cellulose. 

Animals cannot convert acetyl-CoA derived from fatty acids into glucose plants and microorganisms can.

Ceramides and phytoceramides (amides of fatty acids with sphingosine or phytosphingosine) may be linked with galactose (animals) or with glucose (plants). The compounds thus formed are cerebrosides. Close examination of the stracture of these molecules reveals that their amphiphilic nature is intriguing. However, these types of molecules are not readily available and are very expensive. Therefore, their surface-active properties have not been extensively explored and none have become commercially available. 

M.p. 190-192 C. The enolic form of 3-oxo-L-gulofuranolactone. It can be prepared by synthesis from glucose, or extracted from plant sources such as rose hips, blackcurrants or citrus fruits. Easily oxidized. It is essential for the formation of collagen and intercellular material, bone and teeth, and for the healing of wounds. It is used in the treatment of scurvy. Man is one of the few mammals unable to manufacture ascorbic acid in his liver. Used as a photographic developing agent in alkaline solution. 

D-galactose, C HiiOe. Crystallizes in the pyranose form m.p. 1I8-120 C (monohydrate), 165-5" C (anhydrous). An isomer of glucose which is fairly widely distributed in plants. It is a constituent of raffinose and slachyose, of hemicelluloses, of pectin, of gums and mucilages, and of some glycosides. In animals it forms half the lactose molecule and is the sugar found in the brain. Chemically it is very similar to glucose. It has the structure... 

D-glucose, dextrose, C Hi20 . The most common hexose sugar. It is present in many plants, and is the sugar of the blood. It is a constituent of starch, cellulose, glycogen, sucrose and many glycosides, from all of which it can be obtained by hydrolysis with acids or enzymes. 

They are found in a great variety of plants and are strong fish poisons. On hydrolysis they yield a variety of sugars, frequently several molecules to each aglucone. Glucose, galactose, arabinose are the more common pentoses, methylpentoses and glucuronic acid are also obtained. 

This reaction is catalyzed by an enzyme called a dehydratase and is one step along the pathway by which plants convert glucose to certain ammo acids... 

Polysaccharides are macromolecules which make up a large part of the bulk of the vegetable kingdom. Cellulose and starch are, respectively, the first and second most abundant organic compounds in plants. The former is present in leaves and grasses the latter in fruits, stems, and roots. Because of their abundance in nature and because of contemporary interest in renewable resources, there is a great deal of interest in these compounds. Both cellulose and starch are hydrolyzed by acids to D-glucose, the repeat unit in both polymer chains. 

The UOP Sarex process has been used since 1978 for the separation of high purity fmctose from a mixture of fmctose, glucose, and polysaccharides (87,88). The pilot-plant performance of fmctose—glucose separation is given in Table 6.
