An association between sulfur amino acids (methionine, cysteine, homocysteine and taurine) and lipid metabolism has been described in several experimental and population-based studies. Changes in the metabolism of these amino acids influence serum lipoprotein concentrations, although the underlying mechanisms are still poorly understood. However, recent evidence has suggested that the enzyme st...

The traditional method for sparkling wine making consists of a second fermentation base followed by ageing in the same bottle that reaches consumers. Nitrogen metabolism is most important process after carbon and takes place during yeast. Amino acids are numerous nitrogen compounds released this process. They contribute to organoleptic properties wines and, therefore, their sensory quality. mai...

abstract        background and objective: measurement of amino acids is an important tool for metabolic studies and evaluation of patients’ clinical condition. the aim of this study was to analyze the plasma amino acids using reverse phase high performance liquid chromatography techniques (rp-hplc) with pre-column derivatization by o-phthalaldehyde (opa) in combination with 3- mercaptopropionic...

arginine (arg) requirements of male broilers (ross 308) reared at high altitude (2100 mabove sea level) during the 1-to 3-week period was estimated in a graded supplementationmethod, in which six diets (230 g kg-1 cp and 3200 kcal me kg-1) with arg increments of1.25 g kg-1 were applied to four pens of fifteen birds each. dietary arg content of theexperimental groups ranged from 10 g kg-1 (80% o...

Amino acids (AA) are important in poultry nutrition not only for protein deposition, but also for other metabolic functions; such as improving immune and gut functions. Although, some table values are available on amino acids requirement, AA requirements may vary due to changes in dietary composition and breeding selection. Thus amino acids requirements have remained an ongoing research topic. ...

Securigera securidaca (L.) Degen & Dorfl grows in different parts of Iran. The seeds of the species are used in Iranian folk medicine as an anti-diabetic agent. Many studies have established hypoglycemic effects of amino acids and in the present investigation, amino acids of Securigera securidaca seeds have been evaluated. The ground seeds were extracted using petroleum ether,...

A study was conducted to evaluate the interaction of dietary amino acids (AA) concentrations and modern commercial broiler strains . The objective was to determine if broiler strains respond differently to AA supply when raised in similar conditions. Body weight (BW), average daily gain (ADG), feed conversion ratio (FCR), processing yields and protein turnover were evaluated. A total of 4,050 m...
