1、Bright Colors: The molecular model consists of colorful balls and connecting bonds, which are brightly colored, well made, and very safe. The common standard for atomic color makes it easier to use and learn. 2、3D Modeling: Molecular modeling shows the basic molecular structure through 3D modeling studies. It can display molecular structure, molecular bonds and bond angles in all directions. 3、Building Models: Protein molecular models can be used to build models of common and slightly complex protein molecular structures for teaching and laboratory use. 4、Easy to Learn: Molecular model is easy to learn, store and carry. The atoms and bonds are tightly held together and can be easily disassembled with a disconnect tool. 5、Application Scenario: This model kit is used for the structural feature of QH3212‑2 protein molecules in textbooks, which can improve students' learning interest and teachers can explain it more intuitively.
