In biochemistry terms the difference between biosynthesis and cystathionine

is that biosynthesis is the synthesis of organic compounds within a living organism, especially the synthesis of large compounds from small ones while cystathionine is an intermediate, 2-amino-4-(2-amino-2-carboxy-ethyl) thio-butanoic acid, in the biosynthesis of cysteine.

As nouns the difference between intermediate and cystathionine

is that intermediate is anything in an intermediate position while cystathionine is an intermediate, 2-amino-4-(2-amino-2-carboxy-ethyl) thio-butanoic acid, in the biosynthesis of cysteine.
