Upjohn
The Upjohn Company was an American pharmaceutical manufacturing firm (est. 1886) in Hastings, Michigan, by Dr. William E. Upjohn, an 1875 graduate of the University of Michigan medical school. The company was originally formed to make ''friable pills'', specifically designed to crush easily, and thus be easier for patients to digest. Upjohn initially marketed the pills to doctors by sending them a wooden plank along with a rival’s pill and one of Upjohn’s, with instructions to try to hammer the pills into the plank. History Upjohn developed a process for the large scale production of cortisone. The oxygen atom group must be in position 11 for this steroid to function. There are, however, no known natural starting materials with an oxo-group in position 11. The only method for preparing cortisone prior to 1952 was a lengthy synthesis, starting from cholic acid isolated from bile. In 1952, two Upjohn biochemists, Dury Peterson and Herb Murray, announced that they had invente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polysaccharide
Polysaccharides (), or polycarbohydrates, are the most abundant carbohydrates found in food. They are long-chain polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages. This carbohydrate can react with water (hydrolysis) using amylase enzymes as catalyst, which produces constituent sugars (monosaccharides or oligosaccharides). They range in structure from linear to highly branched. Examples include storage polysaccharides such as starch, glycogen and galactogen and structural polysaccharides such as hemicellulose and chitin. Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit. Depending on the structure, these macromolecules can have distinct properties from their monosaccharide building blocks. They may be amorphous or even insoluble in water. When all the monosaccharides in a polysaccharide are the same type, the polysaccharide is called a homopolysaccharide or homoglycan, but when more t ...
