Effect of 24-hours fast on aspartate transaminase activities in the organs of the rat

Abstract

The aspartate transaminase activity of liver, kidney, brain, stomach, small intestine, striated muscle, skin and adipose tissue of fed and 24-hour fasted rats has been studied.The activity level of the enzyme is very much alike in most organs when expressed per unit of protein or DNA weight, in accordance with the general metabolic role of this enzyme.The activity of skin and adipose tissue is considerably lower than that of the other studied organs.A 24-hour fast induced significant increases in the activity of all organs except intestine and stomach.
