In chemistry, a molecular knot is a mechanically interlocked molecular architecture that is analogous to a macroscopic knot. [1] Naturally-forming molecular knots are found in organic molecules like DNA, RNA, and proteins.
20 sie 2015 · This review highlights some of the molecular knotted structures discovered in biology and chemistry. It focuses on the structural and mechanistic studies into which and how knots are formed, and summarises the recent developments made towards understanding their properties and potential functions.
20 sie 2015 · In this review, we provide an overview on the various molecular knots found in naturally occurring biological systems (DNA, RNA and proteins), and those created by synthetic chemists.
9 wrz 2017 · Here we give an overview of synthetic strategies towards molecular knots and outline the principles of knot, braid, and tangle theory appropriate to chemistry and molecular structure. Keywords: interlocked molecules, molecular knots, supramolecular chemistry, template synthesis, topology. Go to: 1. Introduction.
Graphical Abstract. Thou shalt knot …. This Review gives an overview of the field of closed-loop molecular entanglements in terms of their synthesis, and outlines the principles of knot, braid, and tangle theory appropriate to chemistry and molecular structure.
simplest nontrivial knot. A provisional mathematical definition of a knot is: • One-dimensional curve traced in space. • Begins and ends at the same point. • Does not intersect itself. Although the mathematician's idea of a knot differs somewhat from that of a boy scout or sailor, they might ask similar questions.
14 gru 2020 · This 74 knot topology corresponds to that of an endless knot, which is a basic motif of Celtic interlace, the smallest Chinese knot and one of the eight auspicious symbols of Buddhism and...
