What are the structural and functional differences between the n and c terminus of a protein?

The N-terminus and C-terminus of a protein refer to the two ends of the protein chain. The N-terminus is the starting point of the protein sequence, while the C-terminus is the ending point. Structurally, the N-terminus often contains an amino group, while the C-terminus contains a carboxyl group. Functionally, the N-terminus can play a role in protein targeting and stability, while the C-terminus can be involved in protein-protein interactions and signaling.
