Adverb or adjective modifier

The sentences are organized so that the choice seems awkward; if rephrased, it could be either way:

1) "Fructose transport is facilitated similarly to glucose, by........"

2) "Fructose transport, similar to glucose, is facilitated by........."

Take your choice.

Are you sure you want to compare "glucose" to "transport"?

Analogs to the sentence are:

"Similar(ly) to Republican, Democrat ads can be vicious."
"Similar(ly) to plastic, paper products are very cheaply produced."
"Similar(ly) to health, beauty products are on sale today."

I agree. Let me emend:

2) "Fructose transport, similar to that of glucose, is facilitated by..."
