Lipolysis in Isolated Cow Adipose Cells,

Abstract

In vitro, lipolytic activities of isolated adipose cells from dairy cows are sensitive to adrenalins. Glucose, insulin, and nicotinic acid depressed and β-hydroxybutyrate increased fatty acid release rate stimulated by epinephrine. Long term insulin injection and high concentrate feeding depressed lipolytic activities of adipose cells from lactating cows. Lipolytic activities of adipose cells from lactating cows were higher than those from nonlactating cows. High free fatty acid: glycerol release ratios suggested that intense partial hydrolysis of triglycerides occurs in bovine adipose tissue. © 1973, American Dairy Science Association.
