Draw a condensation reaction where a molecule of cysteine combines with a molecule of lysine, showing all reactants and products, and labeling a peptide linkage in your final product. Make sure the structures you draw include all hydrogens (leave every bond labeled and included in your drawing; don't use shorthand).

Use your knowledge of condensation reactions to complete the following tasks.
Protein:
Draw a condensation reaction where a molecule of cysteine combines with a molecule
of lysine, showing all reactants and products, and labeling a peptide linkage in your final
product. Make sure the structures you draw include all hydrogens (leave every bond
labeled and included in your drawing; don't use shorthand).
Carbohydrate:
Draw two ringed a-D glucose monomers forming a disaccharide (maltose). Make sure
to label the glycosidic linkage formed.
