Lipoprotein-bound bile acids in serum from healthy men, postprandially and during fasting.
Individual bile acids were determined by gas-liquid chromatography in, very low density, low density and high density lipoprotein fractions obtained by sequential ultracentrifugation of serum from normal adults, both postprandially and during fasting. The lipoproteins were found to contain 22-34% of fasting serum bile acids. The observed postprandial increase in bile acids did not exhibit any shift in the ratio between lipoprotein bound- and non-lipoprotein-bound bile acids. Bile acids were present in all isolated lipoprotein fractions, high density lipoproteins containing the highest amounts. In the lipoprotein fraction, a higher percentage of cholate than of chenodeoxycholate was found.
