🧪 About the Molecule

Tyrosine is an aromatic amino acid characterized by a chemically versatile phenolic hydroxyl group.

• Chemical Formula: C9H11NO3

• IUPAC / Common Name: Tyrosine

• Structure Coordinates: pubchem

💡 Did You Know?

Tyrosine takes its name from the Greek word 'tyros' (cheese)—it was first discovered in 1846 by German chemist Justus von Liebig in aged cheese curd! Those delicious crunchy little crystals in aged Parmesan cheese are mostly crystallized pure tyrosine!

🌟 Real-World Uses & Fascinating Facts

• 🦋 Thyroid Hormone Core (T3 & T4): Attaching iodine atoms to tyrosine rings creates thyroxine (T4) and triiodothyronine (T3), the master regulators of cellular basal metabolic rate.

• 🎯 No-Crash Focus & Dopamine: A popular nootropic supplement used by pilots, gamers, and athletes to replenish dopamine and norepinephrine depleted by high stress and sleep deprivation.

• 🍫 Melanin Pigmentation: The enzyme tyrosinase converts tyrosine into eumelanin and pheomelanin, generating the brown, black, and red pigments of skin, eyes, and hair.

🧠 Biological Role & Science Notes

Tyrosine's phenolic hydroxyl group can form neutral tyrosyl radicals that facilitate long-range electron transfer in ribonucleotide reductase and Photosystem II. Receptor tyrosine kinases (RTKs) initiate cell growth cascades via tyrosine phosphorylation.

🔬 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!
