- Name and draw the structures of the amino acids that fit the following descriptions:(a) Contains a thiol group (b) Contains a phenol grouparrow_forwardTripeptides are composed of three amino acids linked by peptide bonds. Given a set of amino acids, you can make several different tripeptides.(a) Use the three-letter shorthand notations to name all the tripeptides that can be made from serine, tyrosine, and glycine. Each amino acid will be used once in each tripeptide.(b) Draw the complete structure of the tripeptides that have glycine as the N-terminal amino acid.arrow_forwardGlobular proteins are water-soluble, whereas fibrous proteins are insoluble in water. Indicate whether you expect the following amino acids to be on the surface of a globular protein or on the surface of a fibrous protein.(a) Ala (b) Glu(c) Leu (d) Phe(e) Ser (f) Valarrow_forward
- Taurine (2-aminoethanesulfonic acid) is sometimes called an amino acid. (a) Explain why this designation is not valid. (b) From which of the 20 standard amino acids is taurine derived? Describe the chemical change(s) that occurred.arrow_forwardWhich of the following amino acids is most likely to be found on the outside of a soluble protein, and which of them is more likely to be found on the inside? Explain each answer. (Hint: Consider the effect of the amino acidside chain in each case and that the protein is folded up into its globular form.)(a) Valine (b) Aspartate(c) Histidine (d) Alaninearrow_forward(A) What are Waxes? Draw the structure of wax, which is made up of palmitic acid (16:0) and a saturated 18-carbon alcohol. (В) Consider the structure of menthol. How many isoprene units are present in menthol?

Menthol =arrow_forward
- Identify the following statements as descriptive of the secondary, tertiary, or quaternary structure of a protein. What types of interactions stabilize each type of structure?(a) The polypeptide chain has a number of bends and twists, resulting in a compact structure.(b) The polypeptide backbone forms a right-handed coil.(c) The four polypeptide chains are arranged in a spherical shape.arrow_forwardWhat are the Amino acids and the moieties of the following three structures?arrow_forwardHow many chiral carbons are present in this amino acid (aqueous form)? (Identify the following amino acid (at pH = 7.0): (COO-)–CH(NH3+)–CH2–CH2–CH2–CH2–(NH3+)) zero chiral carbons one chiral carbon two chiral carbons three chiral carbons four chiral carbonsarrow_forward
