EBK GENERAL, ORGANIC, AND BIOLOGICAL CH
- 11.96 Is there a crude association between either measure of adiposity (BMI, WHR), considered separately, and serum estradiol?arrow_forwardTwo of the 20 common amino acids have two chiral carbon atoms in their structures. Identify these amino acids and their chiral carbon atoms.arrow_forwardWhen the amino acid sequences of insulin isolated from differentorganisms were determined, some differences were noted.For example, alanine was substituted for threonine, serine wassubstituted for glycine, and valine was substituted for isoleucineat corresponding positions in the protein. List the single-basechanges that could occur in triplets to produce these amino acidchanges.arrow_forward
- What is the molecular weight of the Botulinum neurotoxin, a protein that contains 1350 amino acids? Assume an average distribution of amino acidsarrow_forwardHistidine is an amino acid with three titratable groups: an -NH3+ group (pKa = 9.2), a -COOH group (pKa = 1.8), and an imidazole (amine-like) group (pKa = 6.0). The titration curve for histidine is shown below with four points highlighted. (a) Identify which point on the titration curve corresponds to the pKa for each of the titratable groups, and which point corresponds to the pI. Explain your choices. (b) Calculate the value of pI for histidinearrow_forwardWhich form of aspartic acid in Problem 18.54 is the zwitterion? What is the pI for the zwitterion?arrow_forward
- For the dipeptide Arg–His, find the pI (the pKs are α-amino 9.0, guanidino 12.5, imidazole 6.0, α-carboxylate 2.1).arrow_forwardThere are 20 standard amino acids and only 10 major monosaccharides in eukaryotes, yet there are so many more possible combinations of monosaccharides in a hexasaccharide than amino acids in a hexapeptide. Explain this observation.arrow_forwardDraw the zwitterion for each of the following amino acids: glycine threonine glutamic acid phenylalaninearrow_forward
- D- and L- designations are used to distinguish between the two possible enantiomers of the monosaccharide, galactose. From the Fischer projection, determine the designation of this monosaccharide.arrow_forwardCasein, a protein in milk, has a molecular formula C38H57O9N9. Determine the total BOD, carbonaceous BOD, and nitrogenous BOD of casein in units of “grams BOD per gram of casein”arrow_forwardProvide the 20 amino acids in this format:arrow_forward
