7.1 Flashcards
What are the similarities and differences in amino acid structure?
Similarities are NH2-C-COOH with H on center C. The difference is in the R group.
Polar
Hydroxyl Carboxyl and Sulfhydro
Acidic
Carboxyl -H
Basic
Amino
Nonpolar
Methyl
Protein Structure
Primary (chain) Secondary (Helix or pleated sheet) Tertiary Quardernary.
Hydrophobic interactions
Center
Hydrophilic interactions
Outside
Acidic and Basic side chains
Acidic attract Basic
Cysteine side chains
Attract to itself
Why and how would the structure and function of a protein change if a hydrophobic amino acid was substituted for a hydrophilic one
It will change the structure’s shape because it now has a hydrophilic amino acid which will go to the outside, following the rules from the tertiary level.
How are the effects and results of protein denaturation different from the effects and results of a mutation?
Denaturation starts at secondary from having a major impact while mutation starts at primary.
