Given the increasing evidence that supports the ability of humans to taste non-esterified fatty acids (NEFA), recent studies have sought to determine if relationships exist between oral sensitivity to NEFA (measured as thresholds), food intake and obesity. Published findings suggest there is either no association or an inverse association. A systematic review and meta-analysis was conducted to ...

Triacylglycerols (TG) of rat milk supply about two-thirds of the energy consumed by suckling rat pups. The present studies were undertaken to determine stereospecific fatty acid composition and molecular species distribution of milk TG and TG produced during digestion, transported in lymph and blood, and present in the liver of 9-- 10-day-old pups. Results support non-random stereochemical fatt...

The concentration of long chain polyunsaturated fatty acid (LCPUFA) in the fetal brain increases dramatically from the third trimester until 18 months of life. Several studies have shown an association between the percentage of maternal plasma docosahexaenoic acid (DHA) during gestation and development of cognitive functions in the neonate. Since only very low levels of LCPUFA are synthesized i...

In hepatocytes from 1-day-old rats, active gluconeogenesis occurs in parallel with active ketogenesis, although the carbon atoms of non-esterified fatty acids do not participate in glucose synthesis. Once a significant ketogenesis is established, a further increase does not enhance gluconeogenesis. Indeed, octanoate is more ketogenic than oleate, but stimulates gluconeogenesis to a similar extent.

I. Prolonged intermittent exposure to reduced environmental temperature (+ 2") produced in rats given a nutritionally well-balanced diet a decrease in the concentration of esterified fatty acids in the blood serum, liver and epididymal fat tissue. In the last there was a significant increase in the unesterified: esterified fatty acid ratio. The hepatic synthesis of fatty acids from [1-14C]aceta...

the present study evaluated the effects of diets enriched in saturated and polyunsaturated fatty acids (n-3and n-6) on reproductive indices, metabolic hormones and metabolites prior to ram introduction in oestrussynchronized ewes. zel ewes (n=188) were assigned to 4 groups. ewes in the control group (con) did notreceive fat. ewes in the 3 other groups received 3% oil/dm/day of palmolein oil (pl...

Esterified astaxanthins are used as functional nutraceuticals and pigments in many food products. Unfortunately, the utilization is currently limited due to their chemical instability and poor water-solubility. In this study, esterified astaxanthins were quantified and purified from Haematococcus pluvialis using a novel and precise approach. By HPLC-(+)APCI-MS/MS, twenty esterified astaxanthin ...
