S-(2-Carboxyethyl)-L-cysteine (S-Carboxyethylcysteine) 是一种非蛋白质(改性)硫氨基酸。S-(2-Carboxyethyl)-L-cysteine 存在于 Acacia 种子中。S-(2-Carboxyethyl)-L-cysteine 可影响大鼠对种子蛋白质的利用。S-(2-Carboxyethyl)-L-cysteine 抑制蛋氨酸诱导的大鼠生长速度，并对大鼠血浆氨基酸水平产生负面影响 S-(2-Carboxyethyl)-L-cysteine (S-Carboxyethylcysteine) is a non-protein (modified) sulfur amino acid. S-(2-Carboxyethyl)-L-cysteine is present in Acacia seed. S-(2-Carboxyethyl)-L-cysteine can affect the seed’s protein use in rats. S-(2-Carboxyethyl)-L-cysteine suppresses the methionine-induced growth rate, and has a negative effect on the plasma amino acid levels in rats.
