The library

A growing library of 3D biology that powers our lessons and build tool. 3D simulations, scenes, proteins and molecules.

Components

A whole 3D scene, mounted by name and driven by a few settings.

WaterSim

Liquid water, and what follows from hydrogen bonds.

  • temperature
  • phase change
  • ice floating
  • salt dissolving
molecules · bulk

Membrane

A bilayer, its proteins, and what crosses.

  • diffusion
  • osmosis
  • selectivity
  • pumps and ATP
  • resting potential
  • chemiosmosis
membrane · bulk

ElectronTransport

Respiration's chain pumping protons out, and the turbine they turn coming back.

  • complexes I–IV
  • NADH and FADH₂
  • no oxygen, uncouplers
  • the ATP getting out
membrane · bulk

LightReactions

Light lifts electrons out of water, and the thylakoid turns that into ATP and NADPH.

  • PSII, b6f, PSI
  • water split, O₂ off
  • NADP⁺ to NADPH
  • one flash at a time
membrane · bulk

Molecule

One molecule in 3D, any in the library by name.

  • an atom lit up
  • hydrogens on or off
  • beside its diagram
molecules · single

Condense

Two molecules joining, and the water that leaves.

  • glycosidic · ester · peptide
  • α against β
  • hydrolysis, run backwards
molecules · single

RespirationReaction

One step of respiration, on two molecules.

  • glycolysis · Krebs · fermentation · the chain
  • click the bond
  • a carrier turning over
molecules · single

Proteinbox

Any protein in the library, from deposited coordinates.

  • primary to quaternary
  • ribbon · surface · fold
  • two side by side
macromolecule · single

HbCrowd

A crowd of hemoglobins, and the moment HbS starts a fibre.

  • HbA against HbS
  • a fibre starting
macromolecule · bulk

BloodCell

One red blood cell, cut open.

  • tonicity
  • lysis and crenation
  • sickling
cell · single

AnimalCell

An animal cell cut open, with its organelles.

  • naming the parts
  • animal against plant
  • vesicle traffic
cell · single

Mitochondrion

One organelle cut open, membrane by membrane.

  • two membranes
  • cristae as sacs
  • the chain, and the protons
organelle · single

Chloroplast

One chloroplast cut open, membrane by membrane.

  • grana and lamellae
  • the light reactions, placed
  • protons, and the oxygen
organelle · single

PlantCell

A plant cell cut open, and what water does to it.

  • turgor and wilting
  • plasmolysis
  • cyclosis
cell · single

Leaf

A leaf in cross-section, tissue by tissue.

  • gas exchange
  • transpiration
  • stomata opening
tissue · bulk

BloodFlow

A vessel of red cells, narrowing.

  • vaso-occlusion
  • stiff against flexible
organ · bulk

Tree

A tree, the air around it, and where its mass came from.

  • Van Helmont's willow
  • day and night
organism · single

Diagram

One molecule, drawn flat, in the notation its chemistry wants.

  • Haworth · Lewis · skeletal
  • lone pairs
  • an atom lit up
no rung · a notation is not in the world

Graph

A chart of measurements, or a live trace off a running sim.

  • scatter · line · bar
  • fit and error bars
  • live trace
no rung · a chart is not in the world

Proteins

Built from real coordinates, measured or predicted.

Molecules

Every molecule the lessons draw, each held to its chemistry by a test.
