Abstract

The invention discloses a gram positive bacteria cell wall model teaching aid which comprises a rectangular base, a first embedded body, a second embedded body and a third embedded body which are embedded on the base, and a grid-shaped mesh body connected to the upper side face of the base, wherein a circular bead string is arranged on the upper side face of the base; and a square bead string is arranged on the top of the mesh body. According to the gram positive bacteria cell wall model teaching aid, the structure characteristics of various special components of the gram positive bacteria cell wall and the correlation among the special components can be vividly displayed, the operational ability of a user can be improved, and the memory is deepened.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to a gram-positive bacteria cell wall model teaching aid. Background technique [0002] The cell wall of Gram-positive bacteria is relatively thick. In addition to containing 15-50 layers of peptidoglycan structure, most of them still contain a large amount of teichoic acid, and a few are teichoic acid, accounting for about 50% of the dry weight of the cell wall. [0003] Teichoic acid is a polymer composed of ribitol or glycerol residues connected to each other through phosphodiester bonds. In its structure, a small number of groups are replaced by amino acids or sugars, and multiple teichoic acid molecules form long chains interspersed in peptidoglycan. in the sugar layer. According to the different binding sites, it can be divided into wall teichoic acid and membrane teichoic acid. One end of the former is covalently bound to muramic acid on peptidoglycan through phospholipids, and ...
