How do we elongate the t1/2 of a peptide...?

-ensuring it has a free N-terminal

-ensuring it has a free C-terminal

-substituting D-a.a. for L-a.a.

-decreasing the number of a.a. in the peptide chain



someone please explain!!!! =)

i think the ans shud be d. the enzyme specificity for d vs the l-aa is different. hence the half- life is likey to be different if the metabolic ez cant work the same way.

i dont think the n or c terminal matter coz endopeptidases exist...decreasing aa wud not decrease t half
