Intramolecular Hydrogen

Longipilin acetate, C23H28O9, is a compound isolated from Espeletia killipii, a Colombian native plant. The molecule contains two non-planar rings, a ten-membered ring and a five-membered lactone. Various substituents around the ten-membered ring provide very weak intramolecular hydrogen-bonding interactions that determine the molecular folding.

Abstract:In many temples in and around Kyoto, sets of wall and slide door paintings and folding screen paintings, which are designated either national treasures or important cultural properties of Japan, have been replaced in situ by high-quality digital reproductions. The original paintings, in turn, are now largely out of sight, placed in storage spaces within temples and museums. Vanguard projects of this nature were conducted in the mid-1990s. Since the mid-2000s, however, and without adequate review of the merits and demerits of such replacement, the practice has accelerated, and numerous sets of slide door paintings have been replaced by reproductions produced for the most part by two competing corporations. The process and implication of such digital replacement require far greater attention and discussion than has to date taken place. Accordingly, this article seeks to clarify the current status of, and problems arising from, the digitization projects taking place in and around Kyoto.

Three Dimensional Space

A new general method is described for obtaining ambient isotopy or regular isotopy invariants of even valence rigid vertex graphs embedded in three-dimensional space. The paper concentrates on the case of 4-valent vertices and defines an RNA vertex in analogy to the structure of a folded molecule. Examples are given to show how these methods can discriminate graph embeddings that are indistinguishable via Vassiliev invariants. Applications to molecular folding are discussed.
