Question 6
Which of the following functional groups found in amino acids are negatively charged at pH 7?
O Carboxylic acids and amides
O Only Carboxylic acids
O Amides and phenols
O Hydroxyls and amides
Question 11
B.1.351 is a variant of SARS-CoV-2. It has the amino acid substitution N501Y in the spike protein
on the virus surface. In cellular fluids at pH 7 the wild type spike protein has a net negative
charge. This substitution will make the spike protein
more negative
less hydrophobic
O less negative
O absorb more UV light
Please provide explanation, thank you!
