Despite early evidence suggesting that dietary cysteine has a sparing effect on methionine requirements, some recent reports question the existence of a measurable sparing capacity.
A thin-layer chromatography method has been developed and evaluated for the separation and determination of lysine and methonine in a mixture of amino acids obtained from acid or enzyme hydrolysis of ...
Elevated plasma homocysteine concentration either in fasting state or after methionine loading is an independent risk factor for vascular disease. The aim of this study was to evaluate the relationsh...
To understand the involvement of polyamines in testicular maturation and spermatogenesis, the activity of two enzymes involved in the polyamine synthetic pathway, L-ornithine decarboxylase (ODC) a...
The authors describe the occurrence of high levels of S-adenosyl-L-methionine decarboxylase (SAMDC) activity in the rat epididymis, and its ontogeny and androgenic control. As early as 15 days of ag...
Follicle stimulating hormone (FSH) modulates testicular function via Sertoli cells. The effect of FSH on S-adenosyl-L-methionine decarboxylase (AdoMetDC) activity was investigated in cultured Sert...
Background: Liver triacylglycerol accumulation and oxidative stress are common in cystic fibrosis (CF) and also occur in choline deficiency. Previously, we showed an association between elevated plasm...
Background: Increased level of serum homocysteine is one of the risk factor of atherosclerosis. Its production related in some sulfur amino acids such as methionine. Some important cofactors that are ...
The 1985 FAO/WHO/UNU upper requirement for the sulfur-containing amino acids in healthy adults, which was set at 13 mg ?kg−1 ?d−1, is based on nitrogen balance studies in Western subjects....
The detailed study by Bosy-Westphal et al (1) in this issue of the Journal echoes and significantly extends observations that have been made in numerous laboratories during the past half century. Howe...
Background: A high plasma homocysteine concentration is an independent risk factor for cardiovascular disease. Homocysteine concentrations are thought to be raised by high protein and methionine ...
Background: Elevated fasting homocysteine concentrations are considered a risk factor for vascular disease. Homocysteine, which is produced by the transmethylation of methionine, can be either reme...
Background: We previously studied methionine kinetics and oxidation with the tracer L-[1-13C, methyl-2 H3]methionine. Objectives: We sought to explore methionine-cysteine interrelations in adults ...
