amino acids Flashcards
what is an R group
determines the amino acid produced
what is a positively charged R group
basic, additional amino acid
what is a negatively charged R group
Acidic, have an actional carboxyl group
what is a polar R group
hydrophilic
what is a non polar R group
hydrophobic
what does the wide range of functions carried out by proteins result from?
The diversity of R groups
what can interactions of the R groups be influenced by?
temperature and pH
what happens when you increase the temperature of the R group?
disturbs the interactions that hold the protein in shape, it unfolds and becomes denatured
what are the charges on acidic and basic R groups affected by?
pH
what happens to the protein as the pH increases or decreases from its optimum?
ionic interactions between charged groups are lost, changes the conformation until its denatured
