the only known microbial habitats that contain similarly high concentrations of simple sugars include saps and fruit nectars, rhizospheres of agro-ecosystems including sugar beets and biofilms on mosses and marine macroalgae14,15.
All of the following affect the rate of diffusion of a substance except a. the concentration gradient of the diffusing particles. b. the presence of other solutes in the solution. c. the density of the solution. a. A dialysis t...

(the relative content of each individual sugar) because fructose, glucose and sorbitol have approximately 1.7, 0.8 and 0.6-fold the sweetener power of sucrose.20 The early findings of Robertson and Meredith21 suggest that low-quality peaches contain lower fructose and higher sorbitol and glucose ...
In addition to these free sugars, sorghum stalks contain cellulose and hemicelluloses, both of which are polymers composed of carbohydrate monomers (hence second generation sugars). Sweet sorghum could therefore be used for the simultaneous production of first and second generation ethanol (Barcelos ...
Several microorganisms have been reported to contain the unusual sugar 6-deoxy-l-talose as a cell wall component. It is the objective of this paper to present experimental evidence for the biosynthesis of this sugar in a cell-free extract of Escherichia coli 045 according to the following ...
[2,9]. Yeasts are considered a well-balanced source of amino acids and can provide vitamins (mainly the B group) [10]. They also contain lower amounts of nucleic acids (5–12%) than bacteria (8–14%), which is beneficial for a human food or animal feed ingredient [2,10]. ...
Which of the following best describes a lipid? A. Lipids are biomolecules that contain the ester functional group. B. Lipids are biomolecules that contain fatty acids. C. Lipids are biomolecules that have negative effects on a person's health. D. Lipids Which of the following substances...
It is distinct from the known glycosidase inhibitors, such as nojirimycin, that contain a nitrogen atom in place of the ring oxygen. In the course of our study on siastatin B (1), we proposed a new class of glycosidase inhibitors, gem-diamine 1-N-iminosugars6–8 (gem-diamine 1-aza-...
