Printed in a single piece using multi-material systems (Prusa MMU3, Bambu AMS, Toolchangers) — no gluing or assembly required!

Generated with the web tool 3D Print Molecules.

🧪 About the Molecule

Lysine is an essential basic amino acid possessing a positively charged primary alkylamino chain.

• Chemical Formula: C6H14N2O2

• IUPAC / Common Name: Lysine

• Structure Coordinates: pubchem

💡 Did You Know?

Cereal crops (wheat, corn, rice) are notoriously deficient in lysine! That is why virtually all ancient human civilizations independently discovered food pairings like beans and rice, pita and hummus, or corn and beans to achieve complete amino acid nutrition!

🌟 Real-World Uses & Fascinating Facts

• 👄 Herpes Cold Sore Shield: Widely taken at the first sign of a cold sore—it competitively blocks arginine uptake, which the Herpes simplex virus requires for replication.

• 🦴 Bone Density & Collagen: Enhances intestinal calcium absorption and creates the covalent pyridinoline cross-links that give bone and collagen their tensile strength.

• 🚗 Fat-Burning Shuttle: The required biochemical precursor for synthesizing L-carnitine, which transports fatty acids into mitochondria to be burned for fuel.

🧠 Biological Role & Science Notes

Lysine residues on histone tails are the primary targets of acetylation and methylation—epigenetic modifications that dictate whether chromatin opens for gene transcription or closes into silence.

🔬 Scientific Precision

• van der Waals Radii: Proportions strictly match standard physical van der Waals radii (Bondi, 1964).

• Conformational Reality: Geometry reflects the lowest-energy real-world conformation derived from computational force fields (MMFF94) and crystallographic/quantum benchmarks.

• CPK Color Standard: Colors follow the classic international Corey-Pauling-Koltun (CPK) palette.

🚀 Why Use the 3D Print Molecules Web App? (3dmolekuly.vscht.cz)

This model was generated using our web visualizer designed to make multi-color 3D printing of molecules seamless:

• 🎯 Automatic Multi-Part Mesh for Multi-Color Printing: No manual cutting or CAD modeling required. The generator automatically isolates each chemical element into separate manifold bodies so PrusaSlicer, Bambu Studio, and OrcaSlicer immediately assign colors!

• 🔬 Authentic Space-Filling Volumes: Generates clean, manifold overlapping sphere volumes reflecting real molecular geometry.

• ⚙ Full Customization: Adjust atom diameters, mesh resolution, scale (mm/Å), and toggle hydrogen atoms on or off.

• 🎓 Free & Web-Based: Developed at the University of Chemistry and Technology, Prague (VŠCHT Praha). Free to use, runs right in your browser with zero installation.

🖨 Multi-Material Printing Instructions

• Style: Space-Filling Spheres (CPK)

• Assembly: None! Printed in one solid piece with multi-material systems.

• Element Color Assignments:

• Carbon (C): Black / Dark Grey

• Hydrogen (H): White

• Oxygen (O): Red

• Nitrogen (N): Blue

• Recommended Layer Height: 0.16 mm (optimal for smooth sphere curves) – 0.20 mm

• Perimeters / Walls: 3

• Infill: 15% Gyroid

• Supports: Tree / Organic supports recommended (use PETG support interface on PLA for 0mm contact distance)

💡 Support Interface Trick for Flawless Spheres

When printing PLA with multi-material units (MMU3, AMS, Toolchanger): Set your Support Interface Material to PETG with Top Z distance = 0 mm. Because PLA and PETG do not bond to each other, the organic/tree supports detach effortlessly by hand with zero surface scarring, leaving the spherical atoms perfectly smooth!
