Comparison of DL-Methionine and L-Methionine levels in liver metabolism activity in commercial broilers fed a diet without antibiotic growth promoters [PDF]

Veterinary World
Background and Aim: Methionine is an essential amino acid in broiler nutrition, playing a crucial role in growth performance and liver metabolism. As an alternative to antibiotic growth promoters (AGPs), this study aimed to evaluate the effects of DL ...

Kinetics and mechanism of the oxidation of methionine by quinolinium chlorochromate [PDF]

Journal of the Serbian Chemical Society, 2005
The oxidation of methionine by quinolinium chlorochromate (QCC) has been studied, in the presence of chloroacetic acid, and in water-acetic acid mixtures of varying mole fractions. The reaction is first order with respect to methionine, QCC and acid. The

Methionine and S-Adenosylmethionine Regulate Monascus Pigments Biosynthesis in Monascus purpureus

Frontiers in Microbiology, 2022
Amino acid metabolism could exert regulatory effects on Monascus pigments (MPs) biosynthesis. In this work, MPs biosynthesis regulated by methionine and S-adenosylmethionine (SAM) was investigated in Monascus purpureus RP2. The results indicated that the

Methionine Nutrition and Metabolism: Insights from Animal Studies to Inform Human Nutrition.

Journal of NutriLife, 2020
Methionine is a nutritionally indispensable amino acid, and is unique among indispensable amino acids due to its sulfur atom. Methionine is involved in cysteine synthesis via the transsulfuration pathway, which is rate limiting for the key antioxidant ...

Metabolism and Endocrine Disorders: What Wnt Wrong?

Frontiers in Endocrinology, 2022
A fundamental question in cell biology underlies how nutrients are regenerated to maintain and renew tissues. Physiologically, the canonical Wnt signaling is a vital pathway for cell growth, tissue remodeling, and organ formation; pathologically, Wnt ...

Life span extension by glucose restriction is abrogated by methionine supplementation: Cross-talk between glucose and methionine and implication of methionine as a key regulator of life span

Science Advances, 2020
Yeast cells lower their intracellular methionine level in response to glucose restriction to regulate metabolism and life span. Caloric restriction (CR) is known to extend life span across species; however, the molecular mechanisms are not well ...

Plasma and Whole Blood Taurine Concentrations in Dogs May Not Be Sensitive Indicators of Taurine Deficiency When Dietary Sulfur Amino Acid Content Is Reduced

Frontiers in Veterinary Science, 2022
BackgroundTaurine status is impacted by dietary supply of methionine and cysteine (SAA) and possibly intestinal microbial activity, where plasma and whole blood taurine concentrations are currently used to evaluate taurine status.ObjectiveWe determined ...

Methionine metabolism and methyltransferases in the regulation of aging and lifespan extension across species

Aging Cell, 2019
Methionine restriction (MetR) extends lifespan across different species and exerts beneficial effects on metabolic health and inflammatory responses. In contrast, certain cancer cells exhibit methionine auxotrophy that can be exploited for therapeutic ...
