Abstract

The utility model belongs to the field of structure model teaching aids, and specifically relates to a structure model teaching aid for glucose molecules. The structure model teaching aid comprises spheres in different colors and connecting rods representing chemical bonds, wherein the spheres in different colors represent different atoms and radicals. Each of the spheres is symmetrically provided with four inserted holes which are ball-shaped. Two ends of each connecting rod are ball-shaped and are capable of being inserted into the spheres via the inserted holes in the spheres. The utility model has the beneficial effects that the connecting rods is capable of rotating in any direction after being inserted into the inserted holes in the spheres, which, thereby, helps teachers change conveniently the Fischer projection of glucose straight chain into the Haworth projection for demonstration in class.

Description

Glucose molecule structural model teaching aid

Technical field

The utility model belongs to teaching mode teaching aid field, is specifically related to a kind of glucose molecule structural model.

Technical background

Saccharide compound occupies very consequence in organic chemistry, and the glucose in the monose is the basis of other carbohydrate of study.The teacher is when the structure of explanation glucose, if there is not the molecular structure model of glucose to demonstrate, the student is with regard to indigestion.But existing ball-and-stick model combined appliance for teaching is limit owing to be distributed in the position of spheroid jack, can not demonstrate the Fischer projection of glucose straight chain well; The connecting link of existing ball-and-stick model combined appliance for teaching is straight type round bar, and in a single day this connecting link inserts in the spheroid and just can not turn.So existing ball-and-stick model combined appliance for teaching can not directly change over the Haworth formula with the Fischer projection.The Fischer projection of the straight chain of glucose can only be write out on the teacher classroom at blackboard, and when the structural change of explanation Fischer projection becomes the Haworth formula, four kinds of structures be on blackboard, write out simultaneously, that is:

Will certainly waste a large amount of time in classroom like this.And when explanation converted ring-type to from open chain, if there is not model demonstration, the student was difficult to the imagination and comes out.Though multimedia can be demonstrated 3-D view well, present most of areas also do not possess this condition.

Summary of the invention

The purpose of this utility model provides a kind of structural model teaching aid of glucose, this glucose molecule structural model teaching aid connecting link is rotation direction arbitrarily, not only can demonstrate the Fischer projection of glucose straight chain, can also demonstrate from the Fischer projection of glucose straight chain and change over the Haworth formula.

The technical solution adopted in the utility model is glucose molecule structural model teaching aid, comprises the versicolor spheroid that represents not homoatomic and atomic group and represents the chemical bond-linking extension bar.Spheroid is made of elastomeric material, and spheroid arranges 4 symmetrical jacks, and jack is ball-type; Connecting link plastic production, connecting link two ends are ball-type, can insert in the spheroid by the jack that is arranged on the spheroid, at this moment just form the spherical hinge structure, connecting link can be in jack rotation direction arbitrarily.The size of jack is just inserted with the ball-type at connecting link two ends part, and can closely be nested together to easily.

Of the present utility model being characterised in that,

Spheroid arranges 4 symmetrical jacks, jack be shaped as ball-type, spheroid is made of elastomeric material, and is flexible, can closely be connected with connecting link; The connecting link two ends are made into ball-type, can insert in the spheroid by the jack that is arranged on the spheroid, connecting link can be in jack rotation direction arbitrarily.

The beneficial effects of the utility model are, connecting link inserts in the jack of spheroid rotation direction arbitrarily, and like this, the teacher demonstrates out with regard at an easy rate the Fischer projection of glucose straight chain being changed over the Haworth formula on the classroom.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated

The utility model provides a kind of glucose molecule structural model, comprises the spheroid 3 that represents atom and atomic group, and as shown in Figure 2 and represent the connecting link of chemical bond, the connecting link two ends are ball-types 1, as shown in Figure 1.Spheroid 3 arranges 4 symmetrical jacks 4, jack 4 be shaped as ball-type, as shown in Figure 2.Spheroid 3 can adopt different colors, different size, represents different atoms or atomic group respectively.Spheroid 3 usefulness elastomeric materials are made, and are flexible, can closely be connected with connecting link; The ball-type part 1 of connecting link can be inserted in the spheroid by the jack 4 that is arranged on the spheroid 3, and connecting link can be done any direction and rotate in jack 4, as shown in Figure 5.Connecting link is made of plastic material.

During use, the ball-type part 1 of connecting link is inserted in the spheroid 3 by jack 4, makes spheroid 3 and connecting link be built into needed glucose structure.

When the Fischer projection of demonstration glucose, can basis

Structural formula is inserted into the ball-type part 1 of connecting link in the spheroid 3 by jack 4, atom C, H and atomic group CHO, OH, CH ₂OH can be distinguished with the spheroid of different colours, different sizes.

Embodiment 1

When the demonstration glucose the Fischer projection be transformed into α-D-glucopyranose Haworth formula, can be according to α-D-glucopyranose Structural formula, represent the connecting link rotation direction between the spheroid of C in the glucose structural model with the Fischer projection, as shown in Figure 6.The spheroid of representative OH above the connecting link is taken off, then the another one color is used for representing the spheroid 3A of O atom, insert this connecting link, as shown in Figure 6, other gets a connecting link, and an end ball-type part 1A of connecting link also is connected with spheroid 3A; Spheroid 3B is connected with this root connecting link other end ball-type part 1B, can form needed α-D-glucopyranose Haworth formula structural model, as shown in Figure 7.
