The absorption bands of cis-unsaturation and the carbon chain length of the fatty acid moieties in oil appear in the near infrared (NIR) wavelength region, especially around 1600-1800 nm. Using this region, a new estimation method for fatty acid composition analysis is proposed. Because the differences of the original NIR spectra are miniscule even in this region, the second derivative NIR spec...

plant fatty acyl-acyl carrier protein thioesterase (fat) is a major enzyme regulating the amount and composition of fatty acids in lipids. in this study, one type of cdna, corresponding to the fatty acyl-acyl carrier protein (acyl-acp) thioesterase (fat) enzyme, was isolated from the seed of brassica napus cv. ningyou12. blast results revealed that the cdna identified highly with the fatb class...

Three species of red marine macro algae (Rhodophyta) from the Indian Ocean were analysed for the occurrence of conjugated polyenes. The composition of different lipid classes in these seaweeds along with their fatty acid composition has also been reported. Analysis of lipid classes of these seaweeds revealed that both Acanthophora spicifera (Ceramiales, Rhodophyta) and two species of Gracilaria...

OBJECTIVE In this study, we analyzed the fatty acid profile of brains and plasma from male and female mice fed chow or a western-style high fat diet (WD) for 16 weeks to determine if males and females process fatty acids differently. Based on the differences in fatty acids observed in vivo, we performed in vitro experiments on N43 hypothalamic neuronal cells to begin to elucidate how the fatty ...

More than 100 years ago, Max Rubner combined the fact that both metabolic rate and longevity of mammals varies with body size to calculate that "life energy potential" (lifetime energy turnover per kilogram) was relatively constant. This calculation linked longevity to aerobic metabolism which in turn led to the "rate-of-living" and ultimately the "oxidative stress" theories of aging. However, ...

This study was conducted to evaluate the chemical composition and fatty acids profile of six predominant date seed cultivars grown in Iran including Barhi, Estamaran, Mazafati, Khasi, Kharak and Zahedi and the biological effects of their tannins based on in vitro gas production. Organic matter digestibility (OMD), metabolizable energy (ME) and concentration of short chain fatty acids (SCFA) wer...

The fatty acid composition of the triglycéridesand phosphatides was determined in mouse epidermis and dermis in anagen and telogen stages of the hair growth cycle (nor mal growth) and compared with fatty acid composition of mouse epidermis and dermis undergoing malignant transformation as a result of the application of methylcholanthrene. The fatty acids of the triglycéridesand phosphatides w...
