This practice is very time-consuming and sometimes the memorized material is lost during the next few days after the evaluations. As the use of mnemonics has proven to be effective in long-term memorization, we propose the use of the Aldoses&#8217; Triangle as a handy tool when dealing with the structures of the C5, C6 aldoses, and C6 ketoses.]]></p></abstract>

Esta práctica consume mucho tiempo y a veces el material memorizado se pierde durante los días siguientes a las evaluaciones. Dado a que el uso de mnemotecnias ha demostrado ser eficaz en la memorización a largo plazo, proponemos el uso del Triángulo de las Aldosas como una herramienta práctica cuando se tiene que lidiar con las estructuras de las aldopentosas, aldohexosas y cetohexosas.]]></p></abstract>
