✦ Synopsis

Double-tethered polymers are a kind of linear polymer with a peculiar topological constraint; that is, both of its endpoints are attached to a plane which the polymer segments cannot penetrate. The effects of the constraint on the polymer's configurational and entropic properties were investigated by means of a three-dimensional lattice simulation that combined a previously proposed idea with a very efficient chain generation algorithm. In particular, the value of a topology-dependent critical exponent was estimated for the double-tethered configurations. This data is the first report on isolated and double-tethered chains. Also, two optional types of tethered-polymer were investigated as asymptotes of the double-and single-tethered configurations.

## Abstract A three‐dimensional lattice model of protein designed to assimilate lysozyme is introduced. An attractive interaction is assumed to work between preassigned specific pairs of units, when they occupy the nearest‐nighbor lattice points. The behavior of this lattice lysozyme is studied by
