obsolete core 1 and core 2 O-glycan biosynthetic process (obsolete GO:0016267)
OBSOLETE. The stepwise addition of carbohydrate or carbohydrate derivative residues to the initially added O-linked residue (usually GalNAc) to form the core 1 O-glycan structure, Gal-beta-(1->3)-GalNAc, and ultimately forming the core 2 O-glycan structure, GlcNAc-beta-(1->6)[Gal-beta-(1->3)]-GalNAc.
