Ercalcidiol is a metabolite of vitamin D2 and is a VDR-like receptor [1].
Vitamin D is a group of fat-soluble secosteroids and plays an important role in enhancing intestinal absorption of calcium, iron, magnesium, phosphate and zinc. Ercalcidiol (25-hydroxy Vitamin D2) and 25-hydroxyergocalciferol (aka 25-hydroxyvitamin D2 — abbreviated 25(OH) D2) are vitamin D metabolites and Ercalcidiol is converted to 25-hydroxyergocalciferol in liver. Through measuring the level of Ercalcidiol and 25-hydroxyergocalciferol in serum can detect the person’s vitamin D status [2] [3].
Using isolated perfused rat kidney model, it was demonstrated that Ercalcidiol not only converted into 24, 25-dihydroxyvitamin D2 but also converted into two other new metabolites-24, 25, 28-trihydroxyvitamin D2 and 24, 25, 26-trihydroxyvitamin D2 [4]. When tested with male weanling rat model, it was demonstrated that either a protein deficiency or a total food restriction during the early postweaning period had no effect on the synthesis and transport of Ercalcidiol and 23, 25-dihydroxyvitamin D in plama [5].

Rapid automated high-performance liquid chromatographic assay for ercalcidiol and calcidiol (25-hydroxyvitamins D2 and D3) using trans-calcidiol as an ultraviolet-absorbing internal standard.[Pubmed:3495546]
J Chromatogr. 1987 Apr 10;415(2):305-16.
A system is described using high-performance liquid chromatography to separate and quantify, by spectrophotometry in a simple one-stage procedure, Ercalcidiol (25-hydroxyvitamin D2) and calcidiol (25-hydroxyvitamin D3). The novel feature of the method is the employment of an ultraviolet-absorbing internal standard to monitor recovery. This has the advantage of permitting total automation of the quantification by eliminating the need for radioactivity counting. The method gives results that compare well with those obtained in other systems and has particular application in clinical studies where rapid separate determination of Ercalcidiol and calcidiol is required.
An in vitro study of vitamin D2 hydroxylases in the chick.[Pubmed:1081537]
J Biol Chem. 1976 Jan 10;251(1):24-8.
An in vitro study of the liver 25-hydroxylation of vitamin D2 and the kidney 1- and 24-hydroxylations of 25-hydroxyvitamin D2 was undertaken in order to determine whether the discrimination against vitamin D2 seen in chicks in vivo is the result of a block of one or more of the steps in the activation of the vitamin D2 molecule. Vitamin D2 hydroxylation reactions in the chick are virtually identical with those observed with the vitamin D3 series. It is, therefore, concluded that the chick possesses the required enzymatic machinery to synthesize 1,25-dihydroxyvitamin D2 and that the discrimination must be because of some unknown metabolic reaction of the vitamin D2 compounds, to a defect in the transport of vitamin D2 metabolites, or to target organ discrimination.
