Following are the properties of proteins at isoelectric pH (pI) except: a. Proteins will have maximum solubility at pI b. Protein possess equal number of positive and negative charges c. Proteins exist in zwitter ionic form d. Below the isoelectric point, they possess net positive charge A B C D

Multiple Choice: Read each question carefully and select the best answer. When will a protein have the lowest solubility? when the pH is above the isoelectric point when the pH is below the isoelectric point C. at neutral pH D at isoelectric pH Which of the following is true of proteins? all proteins are acidic all proteins are basic C. all proteins are neutral D the acid /base properties of a protein depend on the identity ofits side chains Which of the following correctly describes relationship between the primary structure of a protein and protein function? A_ changing one amino acid always affects protein function B only when changing more than one amino acid will have an affect protein function C_ changing one amino acid never affects protein function D there is no relationship between primary structure and protein function
