A dipeptide is made up of two (2) amino acids. The figure above shows one such dipeptide with an unknown sequence. Your task is to find out the two (2) letter sequence of this dipeptide.

Here is a step-by-step guide to help you:

  1. Consult an amino acid guide for reference. You can find a PDF guide on Blackboard under "Exam and Quiz" in the "Old Exams" section, with the filename bchm_exam-help_sheet.pdf, or search online for a visual guide that shows all 20 amino acids with their single-letter codes.
  2. Identify the amino-terminal end, represented as NH3+ and highlighted in bright green. Distinguish between the general nitrogens in amino acid backbones (denoted as NH) and the nitrogen in amino acid side chains.
  3. The one (1) peptide bonds connecting the two (2) amino acids is/are highlighted in bright green, making it easier to distinguish the two (2) amino acids.
  4. Examine the side chain for each of the two (2) amino acids to determine their single-letter amino acid code.
  5. Once you have identified the single-letter codes for the two (2) side chains, list them in the amino to carboxyl (N→C) direction. This is the standard method for writing peptide sequences.
  6. You answer will consist only two (2) letters, no spaces and no other punctuation.

Here is a step-by-step guide to help you:

  1. Consult an amino acid guide for reference. You can find a PDF guide on Blackboard under "Exam and Quiz" in the "Old Exams" section, with the filename bchm_exam-help_sheet.pdf, or search online for a visual guide that shows all 20 amino acids with their single-letter codes.
  2. Identify the amino-terminal end, represented as NH3+ and highlighted in bright green. Distinguish between the general nitrogens in amino acid backbones (denoted as NH) and the nitrogen in amino acid side chains.
  3. The one (1) peptide bonds connecting the two (2) amino acids is/are highlighted in bright green, making it easier to distinguish the two (2) amino acids.
  4. Examine the side chain for each of the two (2) amino acids to determine their single-letter amino acid code.
  5. Once you have identified the single-letter codes for the two (2) side chains, list them in the amino to carboxyl (N→C) direction. This is the standard method for writing peptide sequences.
  6. You answer will consist only two (2) letters, no spaces and no other punctuation.

  1. Consult an amino acid guide for reference. You can find a PDF guide on Blackboard under "Exam and Quiz" in the "Old Exams" section, with the filename bchm_exam-help_sheet.pdf, or search online for a visual guide that shows all 20 amino acids with their single-letter codes.
  2. Identify the amino-terminal end, represented as NH3+ and highlighted in bright green. Distinguish between the general nitrogens in amino acid backbones (denoted as NH) and the nitrogen in amino acid side chains.
  3. The one (1) peptide bonds connecting the two (2) amino acids is/are highlighted in bright green, making it easier to distinguish the two (2) amino acids.
  4. Examine the side chain for each of the two (2) amino acids to determine their single-letter amino acid code.
  5. Once you have identified the single-letter codes for the two (2) side chains, list them in the amino to carboxyl (N→C) direction. This is the standard method for writing peptide sequences.
  6. You answer will consist only two (2) letters, no spaces and no other punctuation.

  1. Consult an amino acid guide for reference. You can find a PDF guide on Blackboard under "Exam and Quiz" in the "Old Exams" section, with the filename bchm_exam-help_sheet.pdf, or search online for a visual guide that shows all 20 amino acids with their single-letter codes.
  2. Identify the amino-terminal end, represented as NH3+ and highlighted in bright green. Distinguish between the general nitrogens in amino acid backbones (denoted as NH) and the nitrogen in amino acid side chains.
  3. The one (1) peptide bonds connecting the two (2) amino acids is/are highlighted in bright green, making it easier to distinguish the two (2) amino acids.
  4. Examine the side chain for each of the two (2) amino acids to determine their single-letter amino acid code.
  5. Once you have identified the single-letter codes for the two (2) side chains, list them in the amino to carboxyl (N→C) direction. This is the standard method for writing peptide sequences.
  6. You answer will consist only two (2) letters, no spaces and no other punctuation.

  1. Consult an amino acid guide for reference. You can find a PDF guide on Blackboard under "Exam and Quiz" in the "Old Exams" section, with the filename bchm_exam-help_sheet.pdf, or search online for a visual guide that shows all 20 amino acids with their single-letter codes.
  2. Identify the amino-terminal end, represented as NH3+ and highlighted in bright green. Distinguish between the general nitrogens in amino acid backbones (denoted as NH) and the nitrogen in amino acid side chains.
  3. The one (1) peptide bonds connecting the two (2) amino acids is/are highlighted in bright green, making it easier to distinguish the two (2) amino acids.
  4. Examine the side chain for each of the two (2) amino acids to determine their single-letter amino acid code.
  5. Once you have identified the single-letter codes for the two (2) side chains, list them in the amino to carboxyl (N→C) direction. This is the standard method for writing peptide sequences.
  6. You answer will consist only two (2) letters, no spaces and no other punctuation.

  1. Consult an amino acid guide for reference. You can find a PDF guide on Blackboard under "Exam and Quiz" in the "Old Exams" section, with the filename bchm_exam-help_sheet.pdf, or search online for a visual guide that shows all 20 amino acids with their single-letter codes.
  2. Identify the amino-terminal end, represented as NH3+ and highlighted in bright green. Distinguish between the general nitrogens in amino acid backbones (denoted as NH) and the nitrogen in amino acid side chains.
  3. The one (1) peptide bonds connecting the two (2) amino acids is/are highlighted in bright green, making it easier to distinguish the two (2) amino acids.
  4. Examine the side chain for each of the two (2) amino acids to determine their single-letter amino acid code.
  5. Once you have identified the single-letter codes for the two (2) side chains, list them in the amino to carboxyl (N→C) direction. This is the standard method for writing peptide sequences.
  6. You answer will consist only two (2) letters, no spaces and no other punctuation.

  1. Consult an amino acid guide for reference. You can find a PDF guide on Blackboard under "Exam and Quiz" in the "Old Exams" section, with the filename bchm_exam-help_sheet.pdf, or search online for a visual guide that shows all 20 amino acids with their single-letter codes.
  2. Identify the amino-terminal end, represented as NH3+ and highlighted in bright green. Distinguish between the general nitrogens in amino acid backbones (denoted as NH) and the nitrogen in amino acid side chains.
  3. The one (1) peptide bonds connecting the two (2) amino acids is/are highlighted in bright green, making it easier to distinguish the two (2) amino acids.
  4. Examine the side chain for each of the two (2) amino acids to determine their single-letter amino acid code.
  5. Once you have identified the single-letter codes for the two (2) side chains, list them in the amino to carboxyl (N→C) direction. This is the standard method for writing peptide sequences.
  6. You answer will consist only two (2) letters, no spaces and no other punctuation.
