Post by: gisellerol on Feb 21, 2022

Question 1.

Which choice shows an accurate bond-line structure for the tetrapeptide Ile-Ser-Leu-Gly?

An illustration shows the bond-line structures of four compounds. The first compound labeled one (Roman numeral) has an eleven-carbon chain, in which C 1 is double bonded to an oxygen atom and single bonded to a hydroxyl group, O H. C 3, C 6, and C 9 are replaced by an N H group. C 4, C 7, and C 10 are double bonded to an oxygen atom. C 5 is wedge bonded to a methylene group which is further bonded to an isopropyl group. C 8 is dash bonded to a methylene group which is further bonded to a hydroxyl group, O H. C 11 is wedge bonded to a methylene group which is further bonded to a propyl group and C 11 is also single bonded to an N H 2 group. The second compound labeled two (Roman numeral) has an eleven-carbon chain, in which C 1 is double bonded to an oxygen atom and single bonded to a hydroxyl group, O H. C 3, C 6, and C 9 are replaced by an N H group. C 4, C 7, and C 10 are double bonded to an oxygen atom. C 5 is wedge bonded to a methylene group which is further bonded to an isopropyl group. C 8 is dash bonded to a methylene group which is further bonded to a hydroxyl group, O H. C 11 is wedge bonded to a methylene group which is further bonded to two methyl groups and also bonded to a and C 11 is also single bonded to an N H 2 group. The third compound labeled three (Roman numeral) has an eleven-carbon chain, in which C 1 is double bonded to an oxygen atom and single bonded to a hydroxyl group, O H. C 2 is bonded to a hydroxyl group, O H. C 3, C 6, and C 9 are replaced by an N H group. C 4, C 7, and C 10 are double bonded to an oxygen atom. C 5 is wedge bonded to a methylene group which is further bonded to an isopropyl group. C 8 is dash bonded to a methylene group which is further bonded to a hydroxyl group, O H. C 11 is wedge bonded to a methylene group which is further bonded to an isopentyl group and C 11 is also single bonded to an N H 2 group. The fourth compound labeled four (Roman numeral) has an eleven-carbon chain, in which C 1 is double bonded to an oxygen atom and single bonded to a hydroxyl group, O H. C 3, C 6, and C 9 are replaced by an N H group. C 4, C 7, and C 10 are double bonded to an oxygen atom. C 5 is wedge bonded to a methylene group which is further bonded to an isopropyl group. C 8 is dash bonded to a methylene group which is further bonded to a thiol group, S H. C 11 is wedge bonded to a methylene group which is further bonded to two methyl groups and also bonded to a and C 11 is also single bonded to an N H 2 group.

The bond-line structure of a compound labeled five (Roman numeral) has a SMILES string of CCC(C)C(C(=O)NC(CO)C(=O)NC(C)C(=O)NC(C(C)C)C(=O)O)N.

Question 2.

What is the correct sequence of amino acids for the given tripeptide?

The bond-line structure of a compound has an eight-carbon chain, in which C 1 is double bonded to an oxygen atom and single bonded to a hydroxyl group, O H. C 2 is wedge bonded to a methylene group which is further bonded to a isopropyl group. C 3 and C 6 are replaced by an N H group. C 4 and C 7 are double bonded to an oxygen atom. C 5 is dash bonded to a methylene group which is further bonded to a three-carbon side chain, in which C 2 is replaced by a sulfur atom. C 8 is wedge bonded to a methyl group which is further bonded to a hydroxyl group and a methyl group. C 8 is also single bonded to an N H 2 group.
