Abstract
Summary. The subcutaneous fat from three male rats reared on a fat‐free diet and three other male rats reared on a diet containing 28 % hydrogenated peanut oil was analyzed at regular intervals for linoleic acid and conjugated dienoic acid. The content of linoleic acid declined rapidly to a low level in both groups. The level of conjugated dienoic acid was almost constant in rats on the fat free diet, but increased to a maximum value of about 2 % in the fat of the rats receiving the hydrogenated peanut oil diet. The hydrogenated peanut oil contained less than 0.1 % conjugated dienoic acid. Thus a certain accumulation of the conjugated acid from this oil has taken place in the adipose tissue. The period in which the subcutaneous fat contains an increased amount of conjugated dienoic acid coincides with the period of growth retardation. The significance of this finding is discussed.
