Etymology: Gk, apo + lipos, fat, protos, first
the protein component of lipoprotein complexes. Apolipoproteins bind to specific enzymes or transport specific proteins and direct lipoproteins to their sites of metabolism. See also apolipoprotein test.
apolipoprotein [ap″o-lip″o-pro´tēn]
a nonlipid protein portion occurring in plasma lipoproteins; there are five families of apolipoproteins, grouped into four classes according to function, A, B, C, and E (the former apolipoprotein D has now been placed in class A). Apolipoproteins play a role in the transport of lipoproteins.
apolipoprotein
a protein moiety occurring in plasma lipoproteins; there are five families of apolipoproteins, designated A-E.
apolipoprotein
Any of a family of small proteins on the surface of lipoprotein complexes, which bind to specific enzymes or transport proteins across cell membranes, which correspond to the protein moiety of lipoproteins. See HDL-cholesterol, Kringle domain.
