Description
Technical field
The utility model relates to a kind of model teaching aid, relates in particular to a kind of Grain-negative bacterium peptide glycan structural model teaching aid.
Background technology
Gram-negative bacteria cell wall is thinner, about 10-15nm, and in cell membrane, peptide glycan content is few, only has 1-2 layer, and every layer thickness is 1nm, accounts for 10% of dry cell weight.Gram-negative bacteria peptide glycan You Ν ?acetylglucosamine, Ν ?the macromolecule complex that is polymerized of the subunit that forms of acetylmuramic acid and a few amino acids short peptide chain, peptidoglycan monomer You Ν ?acetylglucosamine, Ν ?acetylmuramic acid, tetrapeptide side chain form.In order to allow student strengthen understanding and the memory of gram-negative bacteria peptide glycan structure and to distinguish this structure and the difference of gram positive bacteria cell membrane, rely on merely floor map or teaching courseware to satisfy the demand.
Summary of the invention
The purpose of this utility model is cannot know the structure of showing gram-negative bacteria peptide glycan in order to overcome floor map, is convenient to student simultaneously and understands and remember, and a kind of dismountable gram-negative bacteria peptide glycan structural model teaching aid is provided.
The utility model adopts following technical scheme: a kind of gram-negative bacteria peptide glycan structural model teaching aid, comprise the spheroid that represents different amino sugars, and the connecting link that represents glycosidic bond, described spheroid comprises the first spheroid and the second spheroid, it is perpendicular row that described the first spheroid and the second spheroid are spaced, the first spheroid is connected by connecting link with the second spheroid, and described the second spheroid below is provided with pearl shape string.One side level connection joint of the 3rd ball in described pearl shape string has the 4th ball of the pearl shape string of the second spheroid below in adjacent row; Described the first spheroid, the second spheroid, connecting link and pearl shape string form 3-D solid structure.
Further, described the first spheroid and the second spheroid left and right sides are provided with round jack.
Further, described pearl shape string comprises four balls.
Further, the downside of described the second spheroid has jack.
Further, on four balls in described pearl shape string, be respectively equipped with the through hole running through, four balls in described pearl shape string connect by hub rod, and described hub rod upper end is connected in the jack of the second spheroid downside.
Further, the 3rd ball one side in described pearl shape string has hole clipping, and the 4th ball side in adjacent pearl shape string has hub rod, and the 4th ball of described pearl shape string is connected in by hub rod in the hole clipping of the 3rd ball of adjacent pearl shape string.
In superincumbent technical scheme, the first spheroid represent Ν ?acetylglucosamine, the second spheroid represent Ν ?acetylmuramic acid, connecting link representative connect Ν ?acetylglucosamine He Ν ?β-1.4 glycosidic bond of acetylmuramic acid, pearl shape string represents tetrapeptide side chain, wherein the first ball represents that L – alanine, the second ball represent that D – glutamic acid, the 3rd ball represent that diaminopimelic acid, the 4th ball represent D – alanine.
The utility model is simple in structure, for convenience detach, can clearer displaying gram-negative bacteria peptide glycan structure.
