If the sugar is a aldohexose, with the carbonyl in position 1, the reaction may involve the hydroxyl on carbon 4 or carbon 5, creating a hemiacetal with five- or six-member ring, respectively.

(I still remember that from the 5th grade so clearly the rhyming thing really stuck with me) Edit: Now my correction makes no sense, it originally read "For reference anything ending in -ous is sugar." ... and with a primary pKa of 10.28, will only deprotonate at high pH, so is marginally less stable than aldohexose in solution. (carbohydrate) Any hexose containing a ketone group. It should be noted that while both glucose and fructose are hexoses, glucose (an aldohexose) forms a pyranose whereas fructose (a ketohexose) forms a furanose. Look it up now! By convention, the letters ‘ose’ at the end of a biochemical name flags a molecule as a sugar. If the sugar is a 2-ketohexose, it can only involve the hydroxyl in carbon 5, and will create a hemiketal with a five-member ring. I aldoheksoze i ketoheksoze su organski spojevi koji se mogu klasificirati kao monosaharidi koji sadrže šest atoma ugljika. Any member of a group of sugars containing six carbon atoms in the molecule. This means that the functional group present in these sugars is an aldehydic and a ketonic group respectively. For example, glucose is an aldohexose, while ribose is a ketohexose. Chiral vs. Achiral: Definition & Examples. the parallel polypeptide strands that form a B-pleated sheet are stabilized primarily by: hydrogen bonds between amide groups.
