[Determination of the selenomethionine content in grain and human blood].


PMID 10325615

Abstract

The authors used the method of cyanogen bromide-fulorimetry to determine the trace amounts of bound selenomethionine (SeMet) in corn, rice, wheat, soybean and human blood. The contents of SeMet in corn samples were found to be 9.2-19014.1 ng/g, and 45.5% to 82% of the total Se in corn samples were in the form of SeMet. Like corn, the proportion of Se in the form of SeMet in total Se in rice, wheat and soybean were 54.9%-86.5%, 50.4%-81.4% and 62.9%-71.8% respectively. The results showed that SeMet is the major chemical form of Se in grain samples determined. The contents of SeMet in two human blood samples (Se content 56.4 ng/g and 71.8 ng/g) were determined as 28.3 ng/g and 53.4 ng/g respectively.
