dietary factors are suggested to be involved in recent increases in the prevalence of asthma. the differences in dietary intake of 23 asthmatic and 317 non-asthmatic students were investigated, who were chosen by multistage stratified cluster sampling. the dietary data were assessed by food frequency questionnaire and a 24-h recall form. total calorie and fat intake were similar. daily intake o...

Straightor normal-chain, saturated components (even-numbered) make up 10-40% of the total fatty acids in most natural lipids. The most abundant saturated fatty acids in animal and plant tissues are straight-chain compounds with 14, 16 and 18 carbon atoms, but all the possible oddand even-numbered homologues with 2 to 36 carbon atoms have been found in nature in esterified form. They are named s...

Are the different fatty acids mobilized into plasma in proportion to their concentrations in adipose tissue triglyceride? To answer this question, we fed weaning rabbits a special diet to label the fat stores with a variety of dietary fatty acids. The release of adipose tissue fatty acids into the plasma was then induced by ACTH-stimulated lipolysis. The compositions of the resulting plasma fre...

The objective of this study was to investigate the antimicrobial activities of saturated fatty acids and fatty amines against methicillin-resistant Staphylococcus aureus (MRSA). The antimicrobial activity of saturated fatty acids and fatty amines was determined by oxygen meters with multi-channels and disposable oxygen electrode sensors (DOX-96). Lauric acid, the most effective among the satura...

introduction regular intake of n-3 fatty acids of marine origin have desirable effects on serum lipoproteins and reduce coronary vascular disease (cvd). n-3 fatty acid supplementation decreased serum triglyceride concentrations in studies in which most of the subjects were male. the effects of n-3 fatty acids supplementation in fat women especially postmenopausal fat women have received little ...

BACKGROUND This is the second of two review parts aiming at describing the major physiological roles of fatty acids, as well as their applications in specific conditions related to human health. RESULTS The review included the current literature published in Pubmed up to March 2011. In humans, fatty acids are a principle energy substrate and structural components of cell membranes (phospholip...

Fatty acid composition of fish is one of the key factors for the evaluation of fish nutritional value and it could be different based on fish species, habitat, nutrition and etc. The aim of the present study was to evaluate the fatty acid composition of five commercially important freshwater fish from the fish market. Studied fish were as follows: Barbell, Luciobarbus pectoralis (Heckel, 1843),...

Palmitic, stearic, oleic, and linoleic acids at concentrations of 200 nmol/ml all inhibited autolysin activity 80% or more in whole cells or cell-free extracts. This concentration of the saturated fatty acids palmitic acid and stearic acid had little or no effect on the growth of whole cells or protoplasts. However, the unsaturated fatty acids oleic acid and linoleic acid induced lysis in both ...

The fatty acid pattern in hydrocarbon-utilizing filamentous fungi was determined after growth on acetate, propionate, n-alkanes (C(13) to C(15)), and alk-1-enes (C(14) to C(18)). The fatty acid profile of Cunninghamella elegans and Penicillium zonatum after growth on acetate shows a predominance of even-carbon fatty acids (C(16), C(18:1), C(18:2)), whereas cells grown on propionate showed signi...

The proximate analyses of the muscle were: 15% real protein, 1% non-protein nitrogen, 78% humidity and a fatty acid content lower than 1%. The urea reaches values of 2%. In the lipid fraction 14 fatty acids were identified. Palmitic acid (16:0) and stearic acid (18:0) were the majority fatty acids and represent 61.55% and 33-86%, of the total saturated fatty acids. Oleic acid (18:1) was the mos...
