COMPARISON OF THE LIPID-LOWERING EFFECTS OF NICOTINIC ACID AND 2,5-DIMETHYLPYRAZINE IN RATSEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In this study, we compared the non-esterified fatty acid (NEFA)-lowering effects of 2,5-dimethylpyrazine (2,5-DMP) and nicotinic acid (NA), which is found in roasted coffee. Administration of NA to rats induced the "NEFA rebound" while 2,5-DMP did not. Furthermore, co-administration of 2,5-DMP with NA did not result in the "NEFA rebound," giving continuous low concentrations of plasma NEFA. Although the amount of 2,5-DMP in coffee is very low, many kinds of Maillard reaction products such as 2,5-DMP are found in roasted coffee. We also reported that some Maillard reaction products have NEFA-lowering effects. Therefore, we ...

The use of triploid bivalves is now common in the market. We tested if there was a difference in lipid and long-chain highly unsaturated fatty acid (HUFA) accumulation in the muscle of diploid and triploid scallops (Argopecten ventricosus) during maturation, as triploids do not reproduce and lipids are not transferred to the gonad, and thus, could be accumulated in the meat (adductor muscle). Differences in triacylglycerols, phospholipids, esterified and free sterols, as well as HUFA in the reserves of gonads were found between diploid and triploid scallops. In contrast, no differences were found in the muscle for any of t...
