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
The present invention relates to the teaching aid field, relate in particular to a kind of gram positive bacteria cell membrane model teaching aid.
Background technology
The cell membrane of gram positive bacteria is thicker, and except containing 15-50 layer peptide glycan structure, great majority still contain a large amount of LTAs, and minority is phosphorus wall aldehydic acid, accounts for 50% of cell membrane dry weight.
LTA is to be connected to each other the polymer that forms by ribitol or glycerol residue through phosphodiester bond, and the minority group is replaced by amino acid or sugar in its structure, and a plurality of LTA molecular composition long-chains are interspersed in the peptide glycan layer.By its binding site difference, be divided into two kinds of wall teichoic acid and film LTAs, the former end is by the muramic acid covalent bond on phosphatide and the peptide glycan, and the other end stretches out outside cell membrane is free on.Film LTA or claim lipoteichoicacid, the glycolipid covalent bond on an end and the cell membrane skin, the other end passes through the peptide glycan layer and stretches out the cell membrane surface and be free state.
Because the gram positive bacteria cell-wall components is various, interact, when explaining the particular components of gram positive bacteria cell membrane, comparatively complicated, particularly in teaching field, the simple synoptic diagram that relies on is explained, and can not show gram positive bacteria cell membrane particular components and mutual structure and effect thereof intuitively.
