Re: AMBER: Atomic charges in Lactose

  The partial charges for glucose and galactose are in the
Glycam_04.prep file. You will need to build the lactose residue. This
is easily done in leap using the command
x = sequence {OME 4GA 1LB}
This will give you b-D-Gal-(1-->4)-methyl-a-D-Glc. As of now, we do not
have an ensemble charge set for an R-OH, but you can approximate fairly
