Glucose. Glucose like other sugars can exist in a straight chain form or it can loop back on itself and become a ring. If the hydroxyl group on the first carbon atom points down when the ring is formed alpha glucose results and if the hydroxyl group points up the result is beta glucose. alpha glucose. When glucose molecules are enzymatically joined to form a disaccharide a water molecule is removed.
Superbugs are strains of bacteria that have changed (or mutated) after coming into contact with an antibiotic. Once this happens, these bacteria are 'resistant' to the antibiotic to which they have been exposed, which means the antibiotic can't kill the bacteria or stop them from multiplying.
However, what most people don't realize is that MRSA infections are part of a growing trend of superbugâbacterial infections that are resistant to one or more antibiotic(s) that would normally treat the bacteria. 1  In fact, any bacteria can evolve into a superbug. While superbugs can be successfully treated, they are much more challenging than garden-variety infections because, by definition, while a superbug isn't necessarily resistant to all antibiotics, it cannot be treated using two or more.
