== Drawing  Biopolymers with  ChemDraw ==

# Expose the tools by  '''View/Show the Biopolymer Toolbar'''
# Click on AA1 (which produces 1-letter codes) to start a peptide.
# Click on the Ala, then  Ser, then  Ala in the Biopolymer toolbar
# Click on the select tool (square with arrow) from the main  ChemDraw menu to select the whole string, right-click to expose submenu, from which select '''Biopolymer''' then  '''Amino acid style  AA1 <-> AA3'''
# Using the  '''A''' tool from the main  ChemDraw menu, hover over the First H  and replace it with  Ac, and the last  OH with  OEt. 
# You should now have the string '''Ac-Ala-Ser-Ala-OEt'''. 
# Click on the select tool (square with arrow) from the main  ChemDraw menu to select the whole string, right-click to expose submenu, from which select '''Biopolymer''' then '''Expand label'''.   You should get the conventional Chemdraw representation of the tripeptide. 
# If you want to put a protecting group on eg the  OH of Ser,  you can add it at this stage. Although the  ChemDraw help suggests you can add protecting groups as e.g. Ser(tBu), this does not seem to work.
