OBJECTIVE This study was conducted to locate quantitative trait loci (QTL) influencing fatty acid (FA) composition in a large F2 intercross between Landrace and Korean native pigs. METHODS Eighteen FA composition traits were measured in more than 960 F2 progeny. All experimental animals were genotyped with 165 microsatellite markers located throughout the pig autosomes. RESULTS We detected ...

It has been demonstrated that triacylglycerol (TAG) mobilization from adipose tissue is selective and depends on fatty acid (FA) chain length, unsaturation and positional isomerism. The present study was performed to determine the influence of dietary fat on the composition of TAG stored in rat perirenal and subcutaneous adipose tissues. These results may provide information on the susceptibili...

In this study twenty-four male and female one-humped and crossbred (Camelus dromedarius and Camelus bactrianus) camel meat were evaluated during two fattening periods (6 and 9 months). The characteristics of camel meat and fatty acid profile in different parts of body (leg, shoulder, loin and neck) were measured. The results indicated that the pH ultimate of crossbred...

The effects of dietary fatty acids on the composition of Paracentrotus lividus gonads were investigated to determine whether dietary inputs affect their relative abundance during gametogenesis. Egg and embryo FA compositions were compared with that of mature gonads to understand how maternal FA is transferred to the offspring. Urchins were fed an experimental Pellet diet in comparison to brown ...

Title of Document: REGULATION OF MILK FAT SYNTHESIS BY DIETARY FATTY ACIDS ANIL KUMAR G. KADEGOWDA PhD. 2008 Directed By: Professor, Dr. RICHARD ERDMAN, Dept. of Animal and AvianSciences, UMCP. The objectives of this thesis research were to determine the molecular mechanisms by which dietary fatty acids (FA) regulate lipogenic gene expression and milk fat synthesis. Principal component and mult...

In the Netherlands, butter is produced from milk originating from three different production systems: conventional, organic, and grass-fed cows. The aim of the current study was to characterize these types of butters, and pinpoint distinct compositional differences. Retail conventional (n = 28), organic (n = 14), and grass (n = 12) full-fat butters were collected during the winter and summer se...

Intestinal fatty acid binding protein (IFABP) and liver FABP (LFABP), homologous proteins expressed at high levels in intestinal absorptive cells, employ markedly different mechanisms for the transfer of fatty acids (FAs) to acceptor membranes. Transfer from IFABP occurs during protein-membrane collisional interactions, while for LFABP, transfer occurs by diffusion through the aqueous phase. Ea...

Intestinal fat absorption is known to be, overall, a highly efficient process, but much less is known about the efficiency with which individual dietary fatty acids (FA) are absorbed by the adult small intestine. We therefore measured the absorption efficiency of the major dietary FA using sucrose polybehenate (SPB) as a nonabsorbable marker and analyzed how it is modulated by acyl chain physic...

ACUTE AND CHRONIC EFFECTS OF AMPK ACTIVATION ON SKELETAL MUSCLE FATTY ACID AND CARBOHYDRATE METABOLISM Angela C. Smith University of Guelph Advisor: Dr. D.J. Dyck AMP-activated protein kinase (AMPK) has been proposed to be an important energy-sensing enzyme, responding to increases in the AMP:ATP and Cr:PCr ratio. However, AMPK regulation of fatty acid (FA) metabolism and glucose oxidation is n...

Several procedures have been utilized to elevate plasma free fatty acid (FFA) concentration and increase fatty acid (FA) delivery to skeletal muscle during exercise. These include fasting, caffeine ingestion, L-carnitine supplementation, ingestion of medium-chain and long-chain triglyceride (LCT) solutions, and intravenous infusion of intralipid emulsions. Studies in which both untrained and we...
