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.
Antibiotics also kill off some of the âgoodâ bacteria that normally live in your intestines, which may allow resistant bacteria to fill the void. Those bacteria can then multiply and transfer their drug resistance to other bacteria, magnifying the problem. The superbug threat. Superbugs are a growing worry.hose illnesses are usually caused by viruses, not bacteria â and antibiotics donât work against viruses. Doctors know that the drugs donât work for viral infections. But theyâre often all too willing to comply.
