“…In connection with investigations about the alimentary influence on energy efficiency in rats we have found that a glycine rich diet with sufficient amounts of essential amino acids (mixtures of casein and gelatine) reduces significantly the serum triglyceride level [8]. Changing of dietary amino acid pattern towards an excessive intake of individual amino acids leads among others often to an accumulation of lipids in the liver, as shown mainly in experiments with rats [9-131.…”

Feeding of a glycerine rich diet with sufficient supply of essential amino acids (mixture of casein and gelatine) causes a significant reduction of the serum triglyceride level in rats. To study some aspects of this triglyceride lowering effect the in vivo incorporation of C14-1-acetate and C14-1-palmitate into the serum and liver lipids as well as the lipoprotein lipase and the hormone sensitive lipolytic activity of the epididymal adipose tissue in vitro were estimated. After feeding the gelatine containing diet the incorporation of labelled acetate and palmitate into the serum triglycerides was significantly decreased with no change of the incorporation into the liver triglycerides and without detectable accumulation of liver lipids. The decreased serum triglyceride level of the serum corresponded to a decreased lipoprotein lipase activity in the epididymal adipose tissue, whereas the basal and norepinephrine stimulated lipolysis of this tissue was not affected. From these results it is concluded that due to feeding of a glycine rich diet the triglyceride secretion of the liver is decreased leading to a lower serum triglyceride level.

Short communication) I-. AUST, 11. SCHLIEMANN, J. PROLL and G. MIETHPolyester of sucrose and longchain fatty acids (SPE) are prototyps of unabsorbable compounds with fatlike physico-chemical properties [ 1, 21. Their application leads to an increase of fecal cholesterol excretion. which is accompanied by a significant stimulation of the cholesterol synthesis in the liver and partly by a reduction of the lipid level in serum [3,4). SPE are consequently potential substitutes for dietary 1ats in foodstoffs to reduce energy intake and the serum lipid level [5. 61. Earlier animal experiments with 64; '*C-labelled sucrose-octa-palmitate in a semisynthetic diet, however, outlined a very small but not neglectable accumulation raie of lO.-'--lO -5 0 ; in various organs after a feeding time of 7 days or 3 and 6 weeks, respectively [7,8).Because nothing is known about metabolic fate of incorporated SPE the study aimed at the elucidation of the metabolic behaviour of SPE after i.v. injection to mimic a higher accumulation rate.
