Biochemical and physiological effects of sterol alterations in yeast--a review.

abstract：:Tissue and blood fatty acid compositions are used as biological markers of fatty acid intakes to improve dietary assessments. These approaches are invasive and not well accepted, particularly in infants and young children. We developed a sensitive method for the analysis of fatty acids in cheek cell glycerophospholipi...
