Abstract

As part of its everlasting quest for new tastes, new ingredients and new trends, Givaudan traveled to Gabon to explore one of the last unspoiled rain forests in central Africa. This presentation will describe how research teams from the United States and Switzerland explored the incredible bio-diversity on foot and by hovering above the forest canopy in the world’s  largest hot air balloon. In the field, the teams evaluated and collected the aroma of exotic fruits and interesting botanicals. Back in the lab, the aromas were analyzed and successfully reconstituted.  Unique flavor molecules were discovered and commercialized.  Jeff and Xiaogen will describe their adventures in trekking through the Gabon rain forest.  In addition, a discussion of the taste and smell and the related analytical and reconstitution work of some of the exotic botanicals will be presented.

Abstract

It has been well accepted for 75 years that acetylcholinesterase (AChE) has a major catalytic function of hydrolyzing acetylcholine at neuromuscular junctions and at cholinergic nerve synapses.  However, this enzyme is also distributed in tissues of the body where acetylcholine would not normally be found.  This has led to speculation that the enzyme has additional, perhaps noncatalytic, functions one of which may be participation in cell adhesion.  We have been investigating characteristics of AChE in Caco-2 cells.  These cells are derived from a human colon carcinoma and, when grown in culture, show properties similar to intestinal enterocytes.  AChE exists as a single molecular form, membrane bound with the catalytic site facing the external mileau.  The enzyme is anchored to the membrane by a unique mechanism that is usually found primarily in hematological cells.  The unusual characteristics of this enzyme may make it a target for drug-therapy of human cancers.
