Effects of medium- and long-chain triacylglycerols on adipose tissue metabolism in the obese Zucker rat. 1983

J P Max, and A Bach, and E Pallier, and H Schirardin, and G Debry

The influence of a diet including 18 per cent by weight of long-chain (LCT) or medium-chain (MCT) triacylglycerols on adipose tissue development, and on in-vitro adipose tissue triacylglycerol (TG) synthesis from glucose and palmitic acid, was studied using genetically obese, fa/fa, and control, Fa/-, Zucker rats. The adipose tissue mass was greater with the LCT diet than with either the MCT or control diets, but there was no significant difference between the MCT and control diets. TG synthesis from labelled substrates was not modified by the MCT diet when compared with the control, but was decreased by the LCT diet. The results suggested that the use of MCT in treating human obesity would necessitate levels too high to be therapeutically practical.

UI MeSH Term Description Entries
D008297 Male Males
D009765 Obesity A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
D009929 Organ Size The measurement of an organ in volume, mass, or heaviness. Organ Volume,Organ Weight,Size, Organ,Weight, Organ
D011924 Rats, Zucker Two populations of Zucker rats have been cited in research--the "fatty" or obese and the lean. The "fatty" rat (Rattus norvegicus) appeared as a spontaneous mutant. The obese condition appears to be due to a single recessive gene. Zucker Rat,Zucker Rats,Rat, Zucker
D001835 Body Weight The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms. Body Weights,Weight, Body,Weights, Body
D000273 Adipose Tissue Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
