Palmitic acid is the most abundant (approx. 11% of total fatty acids) saturated fatty acid in conventional soybean seed oil. Increasing the saturated acid content of soybean oil improves its oxidative stability and plasticity. We have developed three soybean mutants with high palmitic acid content by X-ray irradiation. In this study, we successfully identified the mutated sites of two of these ...

Saturated fatty acids are implicated in the development of diabetes via the impairment of pancreatic islet β-cell viability and function. Liver X receptors (LXRs) and eicosapentaenoate (EPA) are known regulators of fatty acid metabolism. However, their roles in the pathogenesis of diabetes remain incompletely understood. The aim of this study was to determine the effects of EPA and the LXR agon...

The distribution of long-chain saturated fatty acids in triglycerides is different in infant formulas to that in human milk. In human milk, palmitic acid is predominantly esterified in the sn-2 position (beta-position) of the triglycerides, whereas in infant formulas, it is esterified mainly in the sn-1,3 positions (alpha,alpha'-positions). The specific distribution of the fatty acids in the tr...

The limited availability of alternative foods to replace natural prey hinders cost-effective mass production of ladybird beetles for augmentative biological control. We compared the effects of powdered vs. whole Artemia franciscana (A. franciscana) (brine shrimp) eggs with or without a dietary supplement on development and reproduction of Coleomegilla maculata (C. maculata) (Coleoptera: Coccine...

A growing body of evidence highlights the close association between nutrition and human health. Fat is an essential macronutrient, and vegetable oils, such as palm oil, are widely used in the food industry and highly represented in the human diet. Palmitic acid, a saturated fatty acid, is the principal constituent of refined palm oil. In the last few decades, controversial studies have reported...

Mycobacterium avium accumulates (14)C-palmitic acid with saturation kinetics; the process is both temperature dependent and pH sensitive. The fatty acid is incorporated into triglyceride in vivo and the conversion is detectable within 5 min after exposure of the cells to (14)C-palmitic acid. The triglyceride is rapidly utilized because (14)CO(2) evolution from it begins within 30 min after (14)...

BACKGROUND Hyperlipidemia-induced apoptosis mediated by fatty acid translocase CD36 is associated with increased uptake of ox-LDL or fatty acid in macrophages, hepatocytes and proximal tubular epithelial cells, leading to atherosclerosis, liver damage and fibrosis in obese patients, and diabetic nephropathy (DN), respectively. However, the specific role of CD36 in podocyte apoptosis in DN with ...

The effect of dietary intake of high palmitic acid levels in combination with other fatty acids in normal subjects was assessed. Palmitic acid (10% of energy) was fed in conjunction with decreasing levels of linoleic acid to determine if a threshold level of linoleic acid prevented palmitic acid from being hypercholesterolaemic. Healthy subjects received each of the diet treatments for 21 days,...

Mycobacterium avium, a facultative pathogen for humans, undergoes a life cycle in which selected small cells elongate and then fragment to form coccobacilli. M. avium cells of uniform size were selected by membrane filtration and tested for growth and division in the presence or absence of palmitic acid. Growth was measured by increased cellular protein, and cell division was determined by incr...
