Conflict of interest: The authors declare no conflict of interests. Financial disclosure: None. Ascorbic acid and its derivatives are usually used as antioxidants. They are present in ‘anti-aging’ cosmetics to stimulate production of skin fibroblast procollagen and for the antioxidant properties. There are few case reports of contact dermatitis caused by vitamin C derivatives in cosmetic creams...

intake contributes to raised blood serum cholesterol levels, thus increasing the risk of coronary heart disease Dietary concerns over high saturates contained in edible vegetable (Willett, 1994; Uusitalo et al., 1996). Public perception oils has stimulated development of soybean [Glycine max (L.) Merr.] cultivars with reduced palmitate content. Little is known of factors that of this potential ...

AIMS GPR40/FFAR1 mediates palmitate-induced stimulation of insulin secretion but its involvement in lipotoxicity is controversial. Our previous observations suggest that FFAR1/GPR40 agonists protect against lipotoxicity although the underlying mechanism remains elusive. The present study examines the role of ERK1/2 and GPR40/FFAR1 in palmitate-induced stimulation of insulin secretion and beta c...

A stable-isotope assay was used to analyze the effectiveness of various perdeuterated short-chain acyl coenzyme A (acyl-CoA) compounds as starter units for straight- and branched-chain fatty acid biosynthesis in cell extracts of Streptomyces collinus. In these extracts perdeuterated isobutyryl-CoA was converted to isopalmitate (a branched-chain fatty acid), while butyryl-CoA was converted to pa...

Fatty acid translocase (FAT/CD36) is a key fatty acid transporter in skeletal muscle. However, the effects on fatty acid transport by another putative fatty acid transporter, plasma membrane-associated fatty acid binding protein (FABPpm), have not been determined in mammalian tissue. We examined the functional effects of overexpressing FABPpm on the rates of 1) palmitate transport across the sa...

OBJECTIVES Palmitic acid (PA) comprises 17% to 25% of human milk fatty acids, of which 70% to 75% are esterified to the SN2 position of the triglyceride (SN2-palmitate). In vegetable oils, which are commonly used in infant formulas, palmitate is primarily esterified to other positions, resulting in reduced calcium and fat absorption and hard stools. The aim of this study was to elucidate the ef...

We examined the movement of [3H]palmitate across giant sarcolemmal vesicles prepared from red and white muscle of rainbow trout (Oncorhynchus mykiss). Red and white muscle fatty acid carriers have similar affinities for palmitate (apparent Km = 26 +/- 6 and 33 +/- 8 nM, respectively); however, red muscle has a higher maximal uptake compared with white muscle (Vmax = 476 +/- 41 vs. 229 +/- 23 pm...

BACKGROUND Formula-fed (FF) infants often have harder stools and higher stool concentrations of fatty acid soaps compared to breastfed infants. Feeding high sn-2 palmitate or the prebiotic oligofructose (OF) may soften stools, reduce stool soaps, and decrease fecal calcium loss. METHODS We investigated the effect of high sn-2 palmitate alone and in combination with OF on stool palmitate soap,...
