Simultaneous Treatment of Long-chain Monounsaturated Fatty Acid and n-3 Polyunsaturated Fatty Acid Decreases Lipid and Cholesterol Levels in HepG2 Cell

Autor: Kazuaki Yoshinaga, Seiya Tanaka, Toshiharu Nagai, Yota Mizuno, Samanthika Senarath, Naohiro Gotoh, Aya Yoshinaga-Kiriake, Fumiaki Beppu

Publikováno v: Journal of Oleo Science. 70:731-736

The n-3 type polyunsaturated fatty acids (n-3PUFAs), including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), from fish oil exhibit health benefits such as triacylglycerol- and cholesterol-lowering effects. Some pelagic fishes contain lo

Comparison of the Effects of Long-chain Monounsaturated Fatty Acid Positional Isomers on Lipid Metabolism in 3T3-L1 Cells

Autor: Toshiharu Nagai, Naohiro Gotoh, Kazuaki Yoshinaga, Akihiko Yoshida, Samanthika Senarath, Fumiaki Beppu

Publikováno v: Journal of Oleo Science. 68:379-387

Long chain monounsaturated fatty acids (LC-MUFAs) have shown beneficial health effects in previous studies. They occur as mixtures of positional isomers (PIs) in food. The functionalities of LC-MUFA PIs have not been studied extensively. Common LC-MU

Effect of Calcium Treatment on Catabolic Rates of 13C-Labeled Fatty Acids Bound to the α and β Positions of Triacylglycerol

Autor: Akihiko Yoshida, Yoshio Yamatani, Fumiaki Beppu, Kazuaki Yoshinaga, Jota Kanda, Atsushi Kubo, Aya Yoshinaga-Kiriake, Toshiharu Nagai, Naohiro Gotoh

Publikováno v: Journal of Oleo Science. 68:1149-1155

The absorption efficacies and catabolic rates of fatty acids are affected by their binding position on triacylglycerol (TAG). However, the kind of effect calcium treatment has on the catabolism of fatty acids is unclear. In this study, the catabolic
