Two melanocyte-stimulating hormones have the following amino acid sequences. Take a highlighter or colored pencil, and figure out how much of the sequence the porcine MSH has in common with the human MSH (how much is conserved between the two species). beta-MSH (human): Ala-Glu-Lys-Lys-Asp-Glu-Gly-Pro-Tyr-Arg-Met-Glu-His-Phe-Arg-Trp-Gly-Ser-Pro-Pro-Lys-Asp beta-MSH (porcine): Asp-Glu-Gly-Pro-Tyr-Lys-Met-Glu-His-Phe-Arg-Trp-Gly-Ser-Pro-Pro-Lys-Asp One amino acid interrupts the parts you highlighted in each sequence. Which amino acid was it in each and which category does that amino acid belong to on your amino acid chart? this to make much difference for the cross-species function of beta-MSH (why?)? and Do you expect

The ABO blood group antigens are the terminal sugars covalently linked to the end of the glycolipid in the red blood cellmembrane. The H antigen is the precursor of the A and Bantigens. Individuals with type A blood produce a gene thatcodes for an enzyme that adds N-acetylgalactosamine in ana(1,3) linkage to the Gal* residue in the H antigen. Type Bblood requires that an enzyme add a d-a galactose in an a(1,3) linkage to the Gal*. Draw the structures of the A andB antigens.
