Abstract
The utility model discloses a model which can demonstrate the amino acid molecular structure in condensation course, comprising an amino (1), an R-group (2), a carbon atom (3), a carboxyl (4), and a hydrogen atom (6), the five balls and rod-like bonds (5). The utility model is characterized in that the carbon atom (3) is connected with the amino (2), the R-group (2), the carboxyl (4), and the hydrogen atom (6) respectively by the rod-like bonds (5); the amino (1) and the carboxyl (4) are spheres comprising two hemispheres respectively which are connected with each other by a convex-concave structure. The utility model adopts different colors and marks to differentiate five sections of an amino acid. The structure of the amino acid can be demonstrated in the three-dimensional perspective; meanwhile, the condensation course and the molecular structure of the dipeptide can be expressed, which is an applied teaching mode to make the students easily understand the knowledge of the section.
Description
Technical field
The utility model relates to a kind of model that can demonstrate the amino acid molecular structure, the especially a kind of model that can demonstrate the amino acid molecular structure of condensation course.
Technical background
Amino acid is the base unit of protein, about 20 kinds.Every seed amino acid can be divided into five parts: amino, carboxyl, carbon atom, hydrogen atom and R base, carbon atom spatially have four keys adjacent each other to link to each other with amino, carboxyl, hydrogen atom and R base respectively.Carbon atom in each amino acid, amino, carboxyl, hydrogen atom structure are all identical, and the difference of 20 seed amino acids just is the structure difference of R base.
Mode by condensation between two amino acid forms dipeptides.In an amino amino-OH takes off, with from another amino acid carboxyl, take off-H combines, and forms a molecular water, two taken off respectively-OH and-amino acid residue of H couples together and forms a compound, this compound is called dipeptides.This process is exactly a condensation course.
Through patent retrieval, do not retrieve a kind of amino acid molecular structural model that can demonstrate condensation course.
Above-mentioned knowledge is emphasis in teaching, is again difficult point, relates to the space structure of molecule, knowledge abstraction, and indigestion, the student is difficult to grasp.
Technology contents
The utility model provides a kind of amino acid molecular structural model that can demonstrate condensation course at the characteristics in the teaching.
The utility model is made up of five spheroids, represents amino acid whose five parts respectively: amino, carboxyl, carbon atom, hydrogen atom and R base, use respectively H-NH-,-CO-OH,
-H ,-R represents, the spheroid of expression carbon atom spatially is connected with other four spheroids respectively by four club shaped structures adjacent each other.With the different colours sign, different amino acid whose R bases identify with different digital five spheroids in each amino acid profile more respectively.
Expression spheroid amino and carboxyl is made up of two hemisphere respectively, is formed by connecting by concaveconvex structure between the hemisphere.
If the hemisphere of representative-H in the amino of an amino acid profile is taken off, the hemisphere of representative-OH is taken off in the carboxyl of another amino acid profile, and two hemisphere of taking off couple together by concavo-convex, i.e. expression produces a molecular water.One taken off in the amino-amino acid residue and another amino acid residue of having taken off carboxyl-OH of H promptly form a dipeptides by concavo-convex coupling together again, whole process is exactly the process of condensation.
The utility model is distinguished amino acid whose five parts with different colours and sign, from the amino acid whose structure of the angle demonstration of solid space, can also represent the process of condensation and the molecular structure of dipeptides simultaneously, is convenient to the student and understands the knowledge of this part.It is a very practical teaching mode.
