Concept: Protein structure
5 important questions on Concept: Protein structure
What is a protein?
Why do amino acids differ in their properties?
There are 20 common amino acids. They can be categorized in 5 different subgroups. What are these subgroups?
- the polar/hydrophilic side chains
- highly polar, the side chains contain a carboxlylic acid. Are negatively charged, Acidic.
- positively charged--> basic.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What are some properties of a polypeptide?
Give three ways of visualizing proteins.
- Ribbon model --> shows the backbone and gives the overall shape
- Wire frame model --> shows what the side chaines of each amino acid are doing.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
