That of

This has a a composition comparable to that of blood plasma.

Why say it like that? Isn't this the same meaning?

This has a composition comparable to blood plasma.

Does the former focus more on the similarity between the composition?

They have the same meaning. Prescriptive grammarians will argue that 'that of' is required because 'blood plasma' itself is not a composition; it has a composition. But I would call that nitpicking and I would call the sentence using 'that of' rather hypercorrect here.
