Alpha-linolenic acid and linoleic acid isolated from Ulva fasciata showed toxic effects on red tide phytoplankters in a concentration-dependent manner. Among six species tested, raphidophycean flagellate Heterosigma akashiwo was the most susceptible to these fatty acids, and 50% lethal concentrations (LC50) of alpha-linolenic acid and linoleic acid were estimated to be 0.58 and 1.91 microg/ml r...

The delay in, or loss of, flaxseed lipoxidase activity in N-tris (hydroxymethyl) methylglycine and N-2-hydroxyethylpiperazine-N'-2-ethanesulfonic acid buffers with linolenic acid as a substrate appears due to an alteration of the lipid micelle. Flaxseed lipoxidase activity is dependent on the ionic strength of the assay solution. These effects are not observed with linoleic acid as substrate. T...

Trans polyunsaturated fatty acids are produced during heat treatment of oils, such as deodorization and frying. The detailed metabolic pathways of these trans isomers are not fully understood. In the present work, the desaturation and chain elongation of [114 C]linoleic acid, 9 cis ,12 trans -18:2, 9 trans ,12 cis -18:2, a -linolenic acid, 9 cis , 12 cis ,15 trans -18:3 and 9 trans ,12 cis ,15 ...

Hemp seed (Cannabis sativa L.) is rich in many substances beneficial human nutrition, especially proteins, lipids, and total dietary fibre. Contents of these primary metabolites were analysed seeds hemp cultivar Finola grown at three locations Slovakia (Borovce, Vígľaš-Pstruša, Milhostov) within two years (2013, 2014). The average content fibre was 36.10 ± 1.92%, lipids 32.05 0.42%, proteins 24...

Nanoemulsion is an alternative and promising approach to overcome insolubility and bioavailability problems of bioactive compounds. In this study, the sonication parameter for preparing nanoemulsions with high α- tocopherol and linolenic acid content were optimized by using response surface methodology and their stability were evaluated during 2 months’ storage. The response surface analysis re...

In a study of human milk collected for banking, heating at 62.5 degrees C for 30 min, and freezing and thawing resulted in hydrolysis of triglycerides. Freezing and thawing caused disruption of fat globules and a greater hydrolysis of triglycerides than did the heating process. There was a decrease in the percentage of the poly-unsaturated fatty acids linoleic acid (C18:2) and linolenic acid (C...
