Resumo: The purpose of this qualitative-descriptive work was to identify the operating invariants in the schemes activated by students during the theoretical application of the hydrolysis concept to peptide substances. Different situations (S) were used as referents; the data was collected from representational linguistic sources (L) used as significants, so as to identify the meaning (I) of the hidrolysis concept. the sample was formed by 17 teacher trainees in the areas of Biology and Chemistry of a biochemistry course in the "Instituto Pedagógico de Caracas (IPC)". Two representational categories, A and B, were first identified; afterwards B was maintained and two new catefories, C and D, appeared; all the categories were related to non enzymatic hidrolysis. Only two students were found in the scientifically adequate D category. The results will be usefulr a didactic intervention to allow a meaningful conceptual development of the peptide hidrolysis concept considering the D category

Se usaron algunas situaciones (S) como referentes y se recogieron datos de representaciones simbólicas usadas como significantes (L), para identificar el significado del concepto (I) de hidrólisis peptídica. La muestra consistió de 17 docentes en formación de las áreas de Química y Biología de un curso de Bioquímica del Instituto Pedagógico de Caracas (IPC). Se identificaron inicialmente dos categorías representacionales A y B; posteriormente se mantuvo sólo la B y aparecieron las categorías C y D, todas relacionadas con la hidrólisis no enzimática. la mayoría de los estudiantes se ubicaron en las categorías B y C, y sólo dos en la D, aceptablecientíficamente. Los hallazgos orientarán una mediación didáctica para permitir el desarrollo conceptual significatico del concepto de hidrólisis peptídica considerando la categoría Dapplication/pdfspaRevista de investigación.
