Abstract:
The primary structure of inter-alpha-trypsin inhibitor is partially elucidated, but controversy about the construction of the polypeptide backbone still exists. We present evidence suggesting that inter-alpha-trypsin inhibitor represents a novel plasma protein structure with two separate polypeptide chains covalently crosslinked only by carbohydrate (chondroitin sulphate).
