The essentiality of certain amino acids and certain fatty acids was established for growing rats at about the same time. W.C. Rose at the University of Illinois in the early 1930’s identified 10 essential dietary amino acids for rats. Soon thereafter, these same essential dietary amino acids were confirmed experimentally in growing nonruminant livestock. The fatty acids, linoleic acid (C18:2) a...

Abstract Flax ( Linum usitatissimum L.) is an important source of oil rich in omega–3 fatty acids (especially α-linolenic acid accounting for > 50%), which proven to have health benefits and utilized as industrial raw material. α-Linolenic a polyunsaturated that readily undergoes oxidative transformation. Autoxidation the principal process contributing development off-flavors, loss color, al...

Introduction: Gastric cancer is the fourth common cancer and the second leading cause of death from cancer worldwide. Omega fatty acids are a group of non-saturated fatty acids of long chains derive from linolenic, linoleic and oleic fatty acids. The current study aimed at examining the possible effects of oral administration of omega-3, -6 and -9 fatty acids on gastric cancer cell apoptosis in...

Abstract The following physical tests were carried out for the vegetable oils (refractive index, relative viscosity, smoking point, density), as well chemical (saponification value, peroxide number, and acidity value), estimating amount of vitamin E percentage fatty acids. properties types under study, such value refractive between (1.478), highest flaxseed oil, lowest wheat germ which amounted...

The mechanisms controlling the partitioning of seed composition constituents along the main stem in soybean are still controversial. Therefore, the objective of this study was to investigate seed protein, oil, and fatty acids partitioning in soybean cultivars along the main stem. The cultivars were DT97-4290, maturity group (MG) IV; Stressland, MG IV; Hutcheson, MG V; TracyM, MG VI. Seeds were ...

A total of 48 different volatile oils were identified form P. brevitarsis larvae by gas chromatography/mass spectrometry (GC/MS). Acids (48.67%) were detected as the major group in P. brevitarsis larvae comprising the largest proportion of the volatile compounds, followed by esters (19.84%), hydrocarbons (18.90%), alcohols (8.37%), miscellaneous (1.71%), aldehydes (1.35%) and terpenes (1.16%). ...

The proportions of fatty acids in lipids of subcutaneous adipose tissue was compared in closely age-matched, urban men from two populations with a great difference in mortality from arteriosclerosis, namely in 50 Americans and 56 Japanese aged 15-65 yr who had died suddenly and unexpectedly. Specimens from both groups were analyzed side by side for fatty acids by gas-liquid chromatography. Comp...

The fatty acids, cholesterol compositions and the ratio between unsaturated saturated acids are important parameters for determination of nutritional value certain oils. Most oils sold in our markets claimed they cholesterol- free their acid profile is unknown. To determine commercially vegetable three places, twelve oil samples were analyzed compositions. Cholesterol was detected most sample e...

A comprehensive method for evaluating kernel quality was established by estimating in detail the of 27 pecan cultivars introduced into China and exploring major trait differences among different pecan. The contents crude fat, protein, soluble sugar, tannin; fatty acid composition; amino mineral element composition were analyzed tested using national standards principal component analysis (PCA),...

Many studies show concentrations of nutritionally desirable fatty acids in bovine milk are lower when cows have no access to grazing, leading to seasonal fluctuations in milk quality if cows are housed for part of the year. This study investigated the potential to improve the fatty acid profiles of bovine milk by oilseed supplementation (rolled linseed and rapeseed) during a period of indoor fe...
