Hot Tips to Understanding the 4 Protein Structures

Here is the quick note:


Primary Structure: 
A linear (simple line) polypeptide chain 

Secondary Structure: 
Polypeptide chain shaped into coils (alpha helix) & pleats (beta sheet)

Tertiary Structure: 
Many coils & sheats in 3D! (THREE --> TERTIARY --> 3D)

Quartenary Structure: 
Many tertiary structures combined with non-proteins, forming a complex protein molecule.

TEACHING & MEMORIZING TIPS: Use country analogy to remember the structures' levels:

Primary: Taman Melawati
Secondary: Ulu Klang 
Tertiary: Selangor
Quartenary: Malaysia
