What are the similarities and differences in amino acids?
All amino acids have a carboxyl group and a amino group. However, the difference between the amino acids is that some can be hydrophobic, Hydrophillic, acidic, and basic.
What are the 4 levels of the protein level?
- Primary
- Secondary
- Tertiary
- Quaternary
What happens during protein denaturation?
The secondary, tertiary, and Quaternary structures get destroyed, however, the covalent bonds in the primary structure do not break.
How is the tertiary structure formed by hydrophobic interactions?
It folds towards the inside of the protein
How is the tertiary structure formed by hydrophilic interactions?
It folds towards the outside of the protein
How is the tertiary structure formed by cysteine interactions?
It forms covalent disulfide bonds
How is the tertiary structure formed by acidic and basic interactions?
They attract to each other because of their opposite charges
What function do keratin and collagen serve?
Helps the structure function
What function do channels and pumps serve?
Transportation
Why and how would the structure and function of a protein change if a hydrophobic amino acid was substituted for a hydrophilic one?
The function would change because in the tertiary structure hydrophilic interactions go toward the inside of the protein while hydrophobic interactions go toward the outside of the protein.
How are the effects and results of protein denaturation different from the effects and results of a mutation?
For proteins denaturation the secondary, tertiary, and Quaternary structures are destroyed. However, the effects of a mutation doesn’t always destroy structures and some don’t effect the protein.
