Abstract

Current interest in bioengineering has been extended recently to the exploration of lipase-catalyzed reactions for the commercial processing of oils and fats. Sunflower seedlings, but not dormant seeds, contain a very active lipolytic system associated with oil bodies located incotyledon cells, showing two peaks of maximum activity (pH 3.2 and 8.6) and being notably stimulated by Triton X-100 and higher temperatures (75-85 degrees C). GLC of fatty acids evidenced that the lipolytic system of sunflower shows higher affinity towards saturated fatty acids, and HPLC analysis of the residual triacylglycerols (TAG) revealed lesser affinity for TAG with higher oleic acid content. Some properties of the lipolytic system of sunflower could be potentially useful in bioengineering processes.
