鱼精多肽(Protamine hydrolysate)是由鱼精蛋白(Protamine)酶解作用后形成的多肽片段,含有较大比例的寡肽和氨基酸,具有很高的营养价值和多种生理功能。研究了其体外清除自由基的能力和体内抗疲劳及抗氧化方面的作用,结果发现鱼精多肽粗粉具有较强的羟自由基清除活性,也能明显提高Wistar大鼠的抗疲劳和抗氧化能力。
Protamine hydrolysate is a polypeptide fragment formed by enzymolysis of Protamine, containing a large proportion of oligopeptides and amino acids. It has high nutritional value and a variety of physiological functions. The ability of scavenging free radicals in vitro and anti-fatigue and anti-oxidant effects in vivo were studied. The results showed that crude fishmeat peptides had strong hydroxyl radical scavenging activity, and also significantly improved the anti-fatigue and anti-oxidative activity of Wistar rats ability.
