Possible Interaction: Caseins and Glycine

“Supplementation of casein diet with glycine , alanine, arginine and cystine tended to decrease cholesterol in the sub-fraction of LDL with larger molecular weight.”

“ Glycine has been shown to modify lipid metabolism in liver and blood lipid parameters significantly when supplemented to casein diets alleviating in some studies hypercholesterolemia and atherosclerosis [3–5].”

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

“Mixtures of casein with gelatine (ratio 1:1 and 1:2) as well as the mixture of casein with glycine (in such amount as in the casein-gelatine mixture of 1:1) lead to a postprandial thermogenic action of 16.1%, 19.2% and 14.5%, respectively.”

“With a low-glycine, casein based diet, growth was limited more by glycine than folic acid which improved growth only at 1.69 mg./kg.”

“The fact that the addition of glycine suppresses growth markedly when it is added to a dilute casein digest medium, but does not appreciably hinder sporulation, suggests that the formation of spores is not due to any toxic effect of added compounds, or compounds already present in the medium.”
