Essential fatty acids (EFAs) can be defined by classic definition, which defines EFAs as the fatty acids that are required for proper functioning of cells, but the body cannot synthesize them and, therefore, must be supplied by diet. According to this definition, there are only two EFAs: linolenic acid (LA, C18:2, n-6) and alpha-linolenic acid (ALA, C18:3, n-3). The functional definition of EFA...

Soybeans produced by induced mutation breeding and hybridization were cracked, flaked and hexane-extracted, and the recovered crude oils were processed to finished edible oils by laboratory simulations of commercial oil-processing procedures. Three lines yielded oils containing 1.7, 1.9 and 2.5% linolenic acid. These low-linolenic acid oils were evaluated along with oil extracted from the culti...

The oxidation rates of lauric, myristic, palmitic, stearic, oleic, alpha-linolenic, linoleic, kappa-linolenic, dihomo-gamma-linolenic and arachidonic acids were studied by use of a radioisotope tracer technique in weanling rats at rest in a metabolism chamber over 24 h. Of the saturated fatty acids, lauric acid (12:0) was the most efficient energy substrate: the longer the chain length of the s...

We studied the induction of acid phosphatase (APase) by fatty acids in Saccharomyces cerevisiae. S. cerevisiae has two types of APase: constitutive and repressible enzymes. The synthesis of the latter APase is normally derepressed by depletion of inorganic phosphate (Pi) in the incubation medium. Of the saturated and unsaturated fatty acids tested, linoleic, linolenic and arachidonic acids indu...

I. In Expt I , four adult wether sheep were given diets of hay or dried grass in an alternating sequence of feeding treatments. Each treatment period lasted for 20 days and blood samples were taken from the sheep on the last day of each period. When the diet of hay (linoleic: linolenic acid ratio 1.40) was replaced by one of dried grass (1inoleic:linoltnic acid ratio 0.28), there was an increas...

Soybean (Glycine max (L.) Merr.) oil typically contains 8% α-linolenic acid that is highly unstable and easily oxidized. This property is undesirable in many food and industrial applications. Genetic strategies for reducing α-linolenic acid content would enhance the commercial value. However, genetic resources for low α-linolenic acid content are limited among natural soybean variations. Micros...

The addition of linolenic acid to chloroplasts and sub-chloroplast particles has pronounced effect on light induced absorption changes. At a concentration of 10 —4 M linolenic acid or [LINO]/ [CHL]?«2 (on a mole to mole basis) spectral changes associated with System II are diminished to 50 percent. In this same range there is also a small increase in the spectral change ascribed to System I ; t...

abstract this experiment was conducted to study the effect of south-west climatic conditions on quantitative and qualitative of fatty acids in dog rose (rosa canina l.) seeds collected from five regions including: semirom (isfahan province), kiar and gerdbishe (charmahal and bakhtiari province), yasuj and meymand (kohgiluye and boyer ahmad province). oil was extracted using soxhlet apparatus; t...
