3D Scientific Model of Hemoglobin
Hemoglobin-4HHB 3D Scientific Model — C4D Source Files (RS Rendering)
High-precision 3D model of human deoxyhemoglobin tetramer, constructed based on the PDB 4HHB crystal structure data, with source files in C4D format and rendered using Redshift, accurately depicting the quaternary structure of hemoglobin and the heme cofactor, enabling visualization for structural biology and medical research.
📌 Model Overview
Hemoglobin is a key functional protein in human blood responsible for oxygen transport. It is found within red blood cells and is composed of two α-globin chains and two β-globin chains, forming an α₂β₂ tetramer.. Each subunit contains a cyclic heme group, and the iron ion at its center is responsible for the reversible binding of oxygen molecules. Hemoglobin undergoes significant conformational changes during the binding and release of oxygen—an allosteric switch between the deoxygenated state (T-state) and the oxygenated state (R-state)—and this classic mechanism serves as a paradigm for understanding protein function and allosteric regulation.
PDB 4HHB This is the X-ray crystal structure of human deoxyhemoglobin, which was determined and published by scientists including Fermi and Perutz in 1984, with a resolution of 1.74 Å. This structure is a classic in the field of hemoglobin research and remains one of the most frequently used reference structures in structural biology education and research to this day.
This model is based on the atomic coordinate data for 4HHB and employs C4D (Cinema 4D) Accurate reconstruction of the three-dimensional structure of the hemoglobin tetramer, using Redshift (RS) renderer The rendering of materials and lighting accurately depicts the folded topological structures of the α-subunit and β-subunit, as well as the spatial arrangement of the heme cofactor. The model can serve as Figures in SCI Papers、Academic Presentation core material, which can also be used for Teaching Structural Biology、Visualization in Protein Engineering 及 Science Education Exhibition... is a high-quality 3D resource in the field of structural biology visualization.
✨ Key Highlights
🧬 Structurally accurate, based on experimental data
The model was constructed strictly based on the crystallographic data from PDB entry 4HHB. The tetrameric structure of hemoglobin—comprising two α-chains (red) and two β-chains (blue)—is precisely reproduced according to its actual spatial arrangement. The interaction interfaces between the four subunits and the stacking patterns among them are faithful to the original structure, ensuring the model’s scientific rigor.
🩸 Detailed Depiction of the Heme Cofactor
Each subunit contains a cyclic heme molecule, and the iron ion at its center is the key site for oxygen binding.. In the model, the heme cofactor is rendered in high detail using a separate material, allowing it to be displayed distinct from the subunit body, which makes it easier to highlight protein-cofactor interactions during visualization.。
✨ Redshift professional rendering, with outstanding texture quality
With the help of Redshift GPU-accelerated rendererThe protein surface materials were carefully tailored for the model—the α-subunit and β-subunit feature distinct color schemes, with surfaces exhibiting soft diffuse reflection and a matte finish; the heme cofactor, meanwhile, imparts a metallic sheen that contrasts sharply with the protein body. A multi-angle lighting system perfectly highlights the three-dimensional layering and sense of spatial depth of the tetramer.

💬 About this model
Visualizing the structure of hemoglobin tetramers is a classic topic in structural biology education and research. As a high-resolution structure of human deoxyhemoglobin, 4HHB provides the core basis for this model’s construction through its spatial arrangement of the α₂β₂ tetramer, the interaction interfaces between subunits, and the precise positions of the heme cofactors.. During the model’s construction, PDB atomic coordinate data served as the reference for reconstructing the folding topology and spatial assembly relationships of each subunit in C4D. At the same time, the protein surface materials and lighting parameters were finely tuned to accommodate the characteristics of the Redshift renderer, with the aim of achieving the optimal balance between scientific accuracy and visual impact.
