When 2 glucose molecules are combined what is formed?
Maltose, Trehalose and Cellobiose are all formed solely from glucose molecules. Less common disaccharides of glucose include: Kojibiose, Nigerose, Isomaltose, β,β-Trehalose, α,β-Trehalose, Sophorose, Laminaribiose and Gentiobiose.
What are the examples of disaccharide?
sucrose (common sugar), lactose, lactulose, trehalose, maltose, and cellobiose are common disaccharides.
Which Dissaccharide has alpha 1 1 linked glycosidic bond?
Trehalose also known as Mycose, is a natural alpha-linked disaccharide formed by an α, α-1, 1-glucoside bond between two α-glucose units.
What is this structure?
What sentence structure is this? - It is a simple structure for an interrogative sentence.
Is staphylococcus epidermidis positive for nitrogen reduction?
yes. it is a weak positive for this test though. Better idea for identification would be to run some fermentation tests, like mannitol, sucrose, trehalose and mannose. after you have done some type of growth on salt agar and tested its susceptibility to novobiocin and perhaps lysostaphin.
Trehalose in cosmetic preparation?
Trehalose is a sugar which is found actually in cactus plants. It is this sugar which protects cactus from drying in deserts and retaining water as trehalose has a property of retaining water. This ingredient is used in cosmetics preparation for dry skin. Trehalose protects dry skin and retains moisture of the skin.

Do Belgica Antarctica bite humans?
This animal -- a midge -- survives on and stores trehalose, glucose, and erythritol, which is not sourced in humans.
What are the names of two non-reducing sugars?
The disaccharides Sucrose and Trehalose are both non-reducing sugars.

What is significance of the mycolic acid layer?
Recently, it has been shown that trehalose and mycolic acids are essential for the growth of Mycobacterium tuberculosis, the causative agent of tuberculosis, and Mycobacterium smegmatis, and important but not indispensable to the survival of Corynebacterium glutamicum. Therefore, to investigate the function of mycolic acids in both the permeability of the cell wall to small nutrients and antibiotics, and the excretion of amino acids by C. glutamicum, a trehalose-deficient mutant of the L-lysine producer ATCC 21527, designated LPtreSotsAtreY, was constructed. By using different carbon sources in either the presence or the absence of external trehalose, a set of endogenously trehalose-free LPtreSotsAtreY cells that exhibited various mycolate contents was generated. The results showed that the structure of the arabinogalactan of these different cell types of LPtreSotsAtreY was not affected when the mycolic acid layer was either missing or impaired. Nevertheless, cells were more susceptible to antibiotics, and the permeability of their cell walls to glycerol was increased. Interestingly, a concomitant increase in the excretion of both L-lysine and L-glutamate was also observed, indicating that the mycolic acid content of the permeability barrier (and not only the peptidoglycan and/or the arabinogalactan) is implicated in the glutamate excretion process.see the linkhttp://mic.sgmjournals.org/cgi/content/full/153/5/1424
How long must a common housefly fly without resting in order for it to die of exhaustion?
Studies show that the housefly uses a compound called treahlose to give it the energy for flight.The study in the link shows that a housefly allowed to fly for 4.5 hours, when fed treahlose was able to fly again with being forced to, so it appears to depend on its access to this energy source.It also states that flies who did not have access to treahlose were unable to fly after flight exhaustion.I've often wondered how long I'd need to chase a fly around a room before it dropped dead. If it takes 4.5 hours, I don' think I'll bother. It'd probably just land and walk around indefinately... until I squashed it.The male housefly, Musca domestica, utilizes trehalose during flight. However, the rate of utilization of treahlose is most rapid during the first few minutes of continuous flight (i.e. during the first 5 min of flight, the rate of utilization of trehalose is 187 μg/thorax per hr; this results in a thoracic trehalose level of one-third of that of the unflown fly, after 5 min of flight). However, as the period of flight is extended, the apparent rate decreases very rapidly, so that the thoracic trehalose level actually continues to rise with increasing duration of flight period. It is concluded that, following initial rapid utilization of trehalose, a secondary metabolic pool becomes implicated, so as to restore (and maintain) the thoracic trehalose levels at as high as 50 per cent of that of unflown flies, for thoraces of flies which have been permitted to fly for as long as 4·5 hr. Flight-exhausted flies, when fed on a solution of glucose, fructose, maltose, sucrose, and trehalose, resumed flight, without external stimulation, but feeding galactose, mannose, and cellobiose failed to do so. However, injection of solutions of glucose, fructose, sucrose, and trehalose did not initiate flight in such flight-exhausted flies. These data indicate that a complex, metabolic route is normally involved in the energizing of flight.
