Similarities and differences in amino acid structure
The R group are the only similarities.
Identify whether side chains are nonpolar, polar, acidic, or basic
Hydrophobic- nonpolar
Hydrophilic- polar
Cystine- Acidic
The four levels of protein structure
Primary, Secondary, Tiertiary, Quaternairy
What happens during protein denaturation
The Secondary and Tiertiary structures are undone and only the Primary structure remains the same.
Explain how tertiary structure is formed by interactions between the following:
Hydrophobic interactions
Hydrophilic interactions
Acidic and Basic side chains
Cysteine side chains
Hydrophobic- Go together
Hydrophilic- Form Hydrogen bonds
Acidic and Basic- Attract
Cystiene- Form strong Covalent bonds
Examples of protein types and functions: i.e. enzymes catalyze chemical reactions
Fatty Acids Snythase, Tryptophan Synthase, RuBisCo, pepsin, Amylase
Why and how would the structure and function of a protein change if a hydrophobic amino acid was substituted for a hydrophilic one?
The interactions would be disrupted and incorrect.
How are the effects and results of protein denaturation different from the effect and results of a mutation?
Some mutations can function more properly than others. Mutations aren’t always changing the same parts, denaturation is completely undoing the Secondary and Tiertiary levels.
