CA   (2->3)-O-beta-D-galactopyranosyl-(1->4)-beta-D-glucopyranosyl)-ceramide =
CA   UDP + 1-O-(O-2-(acetylamino)-2-deoxy-beta-D-galactopyranosyl-(1->4)-O-
CA   (N-acetyl-alpha-neuraminosyl-(2->3))-O-beta-D-galactopyranosyl-(1->4)-
CA   beta-D-glucopyranosyl)-ceramide.
CC   -!- Catalyzes the formation of the gangliosides (i.e. sialic-acid-
CC       containing glycosphingolipids) GM2, GD2 and SM2 from GM3, GD3 and
CC       SM3, respectively.
CC   -!- Asialo-GM3 and lactosylceramide are also substrates,
CC       but glycoproteins and oligosaccharides are not substrates.
