Monosaccharide may be defined as the sugars that are not further hydrolyzed or that do not give further sugars on hydrolysis. These monosaccharides are sweet in taste.
Glucose, galactose and fructose are monosaccharide sugars as they cannot be hydrolyzed further to give more sugars. These are colorless and water soluble sugars.
Thus, the correct answer is option (4).
In a child with sore throat, otherwise known as pharyngitis, the most common etiologic agent that causes pharyngitis is adenoviruses. Although, with a high grade fever and a red, inflamed throat, a bacterial etiology can be considered and the most common bacterial agent in pharyngitis is <em>Streptococcus pyogenes. </em>There are suppurative and non-suppurative complications following an untreated streptococcal infection. Suppurative complications (which involves pus) includes tonsillar abscess or collection of pus within the tonsils, otitis media or the infection of the middle compartment of the ear canal, sinusitis, etc. The non-suppurative complications are more serious than suppurative complications. There are two non-suppurative complications, (1) acute rheumatic fever which can progress to rheumatic heart disease which affects the valves of the heart and can ultimately lead to heart failure, and (2) acute glomerulonephritis which involves streptococcal antibodies attacking the glomerular basement membrane in the kidneys and this will present as oliguria (decreased urine production), hypertension (from fluid overload), and hematuria (blood in the urine).
