Lipid Feeding and Serum Esterases

Plasma esterase activities in rats fed diets containing either glucose or fructose

“…Fructose produced a significantly smaller increase in plasma butyrylcholinesterase activity than did glucose. In keeping with previous work [4], this study thus showed that ES-I and butyrylcholinesterase in plasma can respond differently to diet.…”

“…Plasma was prepared by low-speed centrifugation and kept at -20 "C until analysis. Total esterase activity in plasma was measured with p-nitrophenylbutyratc as substrate as described [4]. The method of measuring and reporting ES-I activitics has been described in detail [8].…”

Dietary cholesterol lowers the activity of plasma butyrylcholinesterase in rats

“…Fish oil, when compared with corn oil in the diet, raised the activity of butyrylcholinesterase in plasma of rats [2]. Increased intakes of corn oil at the expense of an isocaloric amount of carbohydrates produced an increment of plasma butyrylcholinesterase activity [3], but with coconut fat no effect was seen [2]. In contrast, OSADA et al [4] reported that feeding of a high-fat versus low-fat diet lowers plasma butyrylcholinesterase activity in rats.…”
