Monossacáridos

<p>Sorbitol, also known as glucitol, occurs widely in plants, such as, the fruits of the Sorbus and Crataegus spp.  Commercially it is produced by the catalytic hydrogenation of glucose (Collins, 2006).  Sorbitol is approved as a sugar substitute with the E number 420 and has ‘generally recognized as safe’ status (GRAS) from the US Food and Drug Administration. It is about 60% as sweet as sucrose and is a mild laxative.  Sorbitol has a wide range of other functional properties, including: humectancy, plasticizing ability, non-cariogenicity, and good chemical stability in harsh conditions, such as, alkaline pH and heat. Toothpaste production is the second largest application of sorbitol, accounting for 50,000 tons a year in Western Europe alone.  Other important uses of sorbitol as a humectant, include: formulation of cough syrups, multivitamin preparations, emulsions, and suspensions (O’Neil, 2013).</p>

<p>Methyl a-D-xylopyranoside is an iron chelator that can be used as a mycobacterial drug candidate. It binds to both ferric and ferrous iron, and has been shown to inhibit the uptake of ferric iron by Mycobacterium tuberculosis. It also inhibits the synthesis of siderophores, which are molecules produced by bacteria in order to acquire iron from their environment.

This is due to its hydroxamate group, which causes it to have an increased affinity for Fe3+. This compound is active against gram negative bacteria such as E. coli and Salmonella enterica serovar Typhimurium, but not against gram positive organisms such as Staphylococcus aureus or Streptococcus pneumoniae.</p>
