**Activity: Drawing the Structure of Histidylthreonine**---**Objective:**Draw the structure of histidylthreonine, a dipeptide made from histidine and threonine, as it would appear at physiological pH.---**Instructions:**In the drawing area provided, you are tasked with constructing the chemical structure of histidylthreonine. This dipeptide combines amino acids histidine and threonine. Use the drawing tools to represent the chemical bonds and structure accurately.**Tools Available:**- **Pencil Tool:** Use this to draw bonds and structures.- **Eraser Tool:** Remove any mistakes or unnecessary parts.- **Move Tool:** Adjust the position of drawn elements.- **Shape Tool:** For creating standard shapes, if needed.**Drawing Box:**- Click and drag to start drawing a structure within the provided box.---**Note:**Consider the ionization state of functional groups at physiological pH while drawing.---**After completing your drawing, click “Check” to verify your work.****Additional Resources:**- Review the typical chemical structures of amino acids.- Refer to pH-dependent ionization states to enhance accuracy.

Histidine is an essential, positively charged amino acid. It contains charged imidazole functional group. Threonine is a polar but neutral (uncharged) amino acid. In the above drawing threonine and histidine are connected by a peptide bond CONH to form histidyl threonine.
