This question belongs a bit in both lists - AMBER and GLYCAM.
So, first the AMBER-level question: What is the amino acid to which you
want to attach the galactose? What are the types of galactose derivative?
It might be that the parameters you need already exist.
If you do need to develop the params, then we'll switch to the GLYCAM list
where you are likely to get a more detailed response.
