using estrogen-induced chick liver cells which synthesize and secrete large amounts of very low density lipoprotein ( vldl ) , we have previously shown ( siuta-mangano , p. , howard , s. , lennarz , w. j. , and lane , m. d. ( 1982 ) j. biol . chem . 257 , 4292-4300 ) that the major protein constituent of vldl , the 350,000 molecular weight apoprotein ( apoprotein b ) , is synthesized as a single polypeptide to which core oligosaccharides are added co-translationally .
