Description of a B 1 Lipoprotein Found in Chylomicron Layer Obtained by Ultracentrifugation of Serum. ∗

Abstract

Summary

We descrive a component of the chylomicron zone obtained by ultracentrifugation of human sera which qualitively resemebles B₁ Lipoprotein in its carotene and acetal lipide content and in its paper electro-phoretic mobility. The increased S₁ observed seems to be related to the high lipide content of this material.
