The anatomy, chemical composition and maximum glycolytic capacity of adipose tissue in wild Svalbard reindeer ( Rangifer tarandus platyrhynchus) in winter
Adipose tissue was dissected completely from 21 female and two male Svalbard reindeer killed in the wild in December 1989. The gross mass, mean adipocyte volume, collagen content, the maximum activities of hexokinase and phosphofructokinase and the fatty acid composition of triacylglycerols were mea...
