- As stated, proteins are stereochemically pure because only a single enantiomer of each amino acid building block is used by nature. How many stereoisomers are possible for a chain of only 3 chiral amino acids if both enantiomers of the amino acids are used? 1. 2 2. 4 3. 8 4. 16arrow_forwardResearchers analysed a glycopeptide (a peptide carrying one or several oligosaccharide groups) and determined both the sequence of the peptide and the sequence of the sugar molecule. The latter was identified as a diholoside coupled to the peptide by an osidic bond. The systematic name of this sugar is: B-D-glucopyranosyl-(1→4)-ß-D-galactopyranose. : Represent the chemical formula of this diholoside in a way that all oses are Question 1 represented according to the Haworth convention. Apart from the furane and/or pyrane cycles all atoms of this molecule must be given.arrow_forwardMatch the region A,B,Carrow_forward
- The configuration of the chiral center in a-amino acids is most commonly specified using the d,l convention. It can also be identified using the R,S convention . Does the chiral center in l-serine have the R or S configuration?arrow_forwardThe pK value for N1 of adenine is 3.64, whereas the pK value for N1 of guanine is 9.50. Explain this diff erence.arrow_forwardGlycine is a diprotic acid, which can potentially undergo two dissociation reactions, one for the a-amino group (-NH3), and the other for the carboxyl (-COOH) group. Therefore, it has two pKą values. The carboxyl group has a pK₁ of 2.34 and the a-amino group has a pK₂ of 9.60. Glycine can exist in fully deprotonated (NH₂-CH₂-COO-), fully protonated (NH3-CH₂-COOH), or zwitterionic form (NH3-CH₂-COO-). Match the pH values with the corresponding form of glycine that would be present in the highest concentration in a solution of th pH. fully deprotonated form NH,−CH,−COO- pH 11.9 pH 6.0 pH 8.0 fully protonated form NH3-CH₂-COOH pH 1.0 Answer Bank pH 7.0 zwitterionic form NH3-CH₂-COO-arrow_forward
- Explain about cysteine residues. How many cysteine residues a α-Keratins has ?arrow_forwardAlthough only l-amino acids occur in proteins, d-amino acids are often a part of the metabolism of lower organisms. The antibiotic actinomycin D, for example, contains a unit of d-valine, and the antibiotic bacitracin A contains units of d-asparagine and d-glutamic acid. Draw Fischer projections and three-dimensional representations for these three d-amino acids.arrow_forwardWhich statement about the glycoprotein shown below is true? OH CH₂OH OH HN HN C - C=0 CH3 H₂ Protein Xo CH N-H Protein It contains a deoxyribose sugar that could be metabolized by human enzymes.
