Possible Interaction: Caseins and Methionine

“In this regard, Yang et al. (3) have recently reported that methionyl-methionine enhances as1 casein synthesis by cultured bovine mammary explants.”

“The ability of κ-casein to prevent the amorphous aggregation of target proteins was slightly enhanced upon methionine oxidation, which may arise from the protein's greater exposed surface hydrophobicity.”

“Supplementation of the 10% casein diet with methionine significantly increased the hepatic SAM concentration, PC/PE ratio, delta 6-desaturase activity, and arachidonate/linoleate ratio, whereas cystine supplementation had no or little effect on these variables.”

“ Methionine supplementation increased protein and casein concentrations and outputs.”

“The larger increment of methionine concentrations in the blood after feeding of OM with a casein diet and the rapid absorption of amino acids from casein may result in much growth improvement in rats.”

“Similarly, the 30-min portal Met concentration significantly increased in response to the casein + OM diet compared with the SPI + OM diet regardless of the prefed proteins (25% casein and 25% SPI for 2 wk).(ABSTRACT TRUNCATED AT 250 WORDS)”

“The ratio of the postprandial increment of Met concentration to that of Gly concentration in the portal plasma was significantly higher when casein and its amino acid mixture were fed than when SPI and its amino acid mixture were fed.”

“When a 10, 20 or 40% casein diet supplemented with 0.1, 0.2 or 0.4% L-methionine , respectively, was fed to rats, the urinary excretion of MNA decreased, and that of 4-pyr increased, as the level of dietary casein and methionine increased.”

“A simultaneous supplementation of Met and Gly to casein resulted in a reduction of hepatic cholesterol.”

“Xanthine oxidase activity in intestinal mucosa of the rats fed the 5% casein + methionine diet was significantly greater than that of the rats fed the 5% casein diet alone.”
