Hi, please help 1)Draw two molecules that could hydrogen bond with each other. Draw and indicate the H-bond and label which is the donor and acceptor. 2) Look up the structure of the subunit of hemerythrin, an oxygen binding protein from invertebrates. It has been found that in some α-helical regions of the protein, about every third or fourth amino acid residue is a hydrophobic one. Suggest a reason for this finding, based on the structure you found. 3) Which...

Hydroxychloroquine (HCQ) has been in the news recently as a possible treatment for COVID-19 infections. We do not know much about its efficacy or we are not in a position to discuss about its clinical details. However, from a pure chemistry viewpoint find out the structure of HCQ and Chloroquine and copy paste them below. Also these discussion mentions about the importance of Zinc supplements along with HCQ or chloroquine. We do not know the exact mechanism or its interactions....
