Cholesteryl Fatty Acid Esters and Free Cholesterol in Food of Animal Origin
European Journal of Lipid Science and Technology, Volume 128, Issue 1, January 2026.Cholesterol occurs in free (bioavailable) and esterified (transport/storage) forms. Here, we present a method that allows both forms to be determined independently. Finally, the quantities of free and esterified cholesterol were determined in several meat, animal fat, and cheese samples.

Health Science Reports, Volume 8, Issue 12, December 2025.ABSTRACT Background and Aims Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder caused by mutations in the CYP27A1 gene, leading to deficient sterol 27‐hydroxylase activity. This enzyme is critical for bile acid synthesis, and its dysfunction results in reduced chenodeoxycholic acid (CDCA) levels and subsequent accumulation of ...
