Possible Interaction: Proline and Glutamic Acid

“Of the downstream taste signalling genes that were analysed in parallel, plcb2 and possibly trpm5 (non-significant trend) were down-regulated 20 min after proline and glutamic acid treatment.”

“The apparent digestibility of alanine (P = 0.05), aspartic acid (P = 0.07), glutamic acid (P = 0.02), glycine (P = 0.05), proline (P = 0.02), and serine (P = 0.04) responded quadratically to CP content increase.”

“Compared with DON treatment, dietary supplementation with glutamic acid increased the plasma concentrations of proline , citrate, creatinine, unsaturated lipids, and fumarate, and decreased the concentrations of alanine, glycoprotein, TMAO, glycine, and lactate, as well as the glutamate/creatinine ratio (P<0.05).”

“During differentiation the taurine, glutamic acid , GABA, glutamine, aspartic acid, glycine arginine, methionine and histidine levels increase while proline.”

“However, a minimal requirement for arginine was found to be about 0.3% of the diet even when proline and glutamic acid were both added in excess.”

“Of the downstream taste signalling genes that were analysed in parallel, plcb2 and possibly trpm5 (non-significant trend) were down-regulated 20 min after proline and glutamic acid treatment.”

“It is unlikely that the proline accumulation in detached leaves is to be derived solely from protein hydrolysis, since the addition of l-glutamic acid increased the proline level during senescence.”

“Repression of the biosynthesis is less if glutamic acid is added in mixtures with proline , beta-alanine and asparagine.”
