Sulfoquinovosyldiacylglycerol (SQDG) contents in conifer leaves and their fatty acid (FA) compositions were determined. The SQDG content was 16-36 mg/100 g, and was high in Picea glehnii. Palmitic and alpha-linolenic acid were the usually predominant FAs. In Picea, the proportion of alpha-linolenic acid was low, and those of oleic and linoleic acid were high. The essential oil residues of Abies...

This study examined the effects of dietary alpha-linolenic acid deficiency followed or not by supplementation with phospholipids rich in n;-3 polyunsaturated fatty acid (PUFA) on the fatty acid composition of total phospholipids in 11 brain regions. Three weeks before mating, mice were fed a semisynthetic diet containing both linoleic and alpha-linolenic acid or deficient in alpha-linolenic aci...

Vessel occlusion is the most frequent cause for impairment of local blood flow within the brain resulting in neuronal damage and is a leading cause of disability and death worldwide. Polyunsaturated fatty acids and especially alpha-linolenic acid improve brain resistance against cerebral ischemia. The purpose of the present study was to evaluate the effects of polyunsaturated fatty acids and pa...

OBJECTIVES The goal of this study was to examine whether higher consumption of total linolenic acid was associated with rate-adjusted QT and JT intervals (QTrr and JTrr, respectively). BACKGROUND Higher intake of fish omega-3 fatty acids and plant omega-3 such as alpha-linolenic acid is associated with lower risk of myocardial infarction. While long-chain omega-3 can inhibit ventricular arrhy...

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...

Dietary triglycerides containing predominantly poly-unsaturated fatty acids (PUFAs) are known to reduce plasma total and low density lipoprotein (LDL) cholesterol concentrations relative to triglycerides containing predominantly saturated fatty acids. However, there is little information regarding the independent effects of individual n-6 and n-3 PUFAs on LDL metabolism. The present studies wer...

Conjugated linolenic acids (CLN) are geometric and positional isomers of linolenic acid. Growth inhibition and apoptosis induction by alpha-eleostearic acid (c9,t11,t13-CLN), beta-eleostearic acid (t9,t11,t13-CLN), alpha-calendic acid (t8,t10,c12-CLN) and beta-calendic acid (t8,t10,t12-CLN) were compared. beta-Eleostearic acid and beta-calendic acid, which have all-trans-conjugated double bonds...
