Class 11 Zoology simulations · Biomolecules

Levels of protein structure

Fold a protein from its amino acid sequence to a helix, a 3D globule and finally a multi-subunit protein.

Open the simulation

What to notice

The tertiary structure gives the protein its 3D shape and biological activity.

Key relation

Primary → secondary → tertiary → quaternary

Try this

Step to quaternary structure and count the subunits of haemoglobin.

What you can change

• Structure level: choose Primary, Secondary (α-helix), Tertiary, Quaternary

More in Biomolecules

• Temperature and pH affect enzymes
• Enzyme action and competitive inhibition
