Acid adaptation of Streptococcus mutans UA159 involves several different mechanisms, including the ability to alter its proportion of long-chain, monounsaturated membrane fatty acids (R. G. Quivey, Jr., R. Faustoferri, K. Monahan, and R. Marquis, FEMS Microbiol. Lett. 189:89-92, 2000). In the present study, we examined the mechanism and timing of changes in fatty acid ratios and the potential b...

Adipose tissue fatty acids, it has been proposed, reflect dietary intake. Using data from a validation study preceding a prospective study on diet, cancer, and health in Denmark, we were able to compare fatty acid profiles in adipose tissue biopsies from 86 individuals (23 men and 63 women) aged 40-64 y and dietary intake of fatty acids (as percentage of total fat) assessed by two 7-d weighed-d...

seasonal variation of fatty acids composition of milk and various milk products have been subjected to many investigations.however ,most of the researches are concerned with a single product and apparantly there is no inforation about the extent and the factors which contribute to changes in fatty acids composition of lipids in the process of ghee-making by the  traditional methods.thus compara...

Seasonal variations of proximate compositions and fatty acids of tench (Tinca tinca) captured from Seyhan Dam Lake were investigated. The results showed that seasonal fatty acid compositions of tench fillets in July, August and November ranged from 29.59% to 33.71% for saturated fatty acids (SFA), from 20.50% to 21.69% for monounsaturated fatty acids (MUFAs) and from 26.50% to 41.85% for polyun...

The effects of hydrocarbons and hydrocarbon derivatives as growth substrates on the polar lipid fractions of an Acinetobacter isolate were studied. Tetradecane, hexadecane, and octadecane resulted in the incorporation of substantial quantities of equivalent-chain-length fatty acids into cellular lipids. Cells cultured on nonane, the only odd-numbered alkane tested, contained both odd- and even-...

The analysis of fatty acid profiles of lipopolysacharid.es has shown that R. solanacearum strains tested may be divided into two groups. The first group is represented by R. solanacearum strains (5712, 7945, 7955 and 8110) the lipids A of which contained hydroxylated fatty acids with long chains: 3-hydroxy­ tetradecanoic, 2-hydroxyhexadecanoic and 2-hydroxyoctadecanoic. The second group was rep...

Objective: To assess the implications of new recommendations for essential fatty acids, vitamin D and vitamin E on the classification of margarines and vegetable oils as ‘extras’ in the current Australian Guide to Healthy Eating. Design: The role of margarines and vegetable oils as sources of essential fatty acids, vitamin D and vitamin E was examined in two ways. First, data from the 1995 Nati...

The purpose of this study was to develop a pharmaceutical formulation containing fatty acid extract rich in free omega-3 fatty acids such as eicosapentaenoic acid and docosahexaenoic acid for topical use. Although the health benefits of cod liver oil and other fish oils taken orally as a dietary supplement have been acknowledged and exploited, it is clear that their use can be extended further ...

to estimate the effect of microencapsulated fish oil on blood metabolites, rumen and blood plasma fatty acids concentrations twelve sannan dairy goats with 30 ± 5 days in milk (dim) were allocated to 3 treatments in a 3×2 change over design with 2 periods of 30 days. treatments were: 1) the control (without fish oil), 2) microencapsulated fish oil (2% fish oil capsulated in 6% treated whey prot...

The visceral storage fat and liver of patin catfish (Pangasianodon hypophthalmus) are normally discarded, which incurs cost and can cause environmental pollution. However, these may be potential sources to extract fish oil. The proximate and fatty acid compositions of liver and fatty tissue of patin catfish were investigated to evaluate the suitability of these by-products for extracting fish o...
