Abstract:
Amino acids are significant biomolecules that govern the major metabolic processes and act as precursors for macromolecules such as proteins that are crucial to life. Fish is an integral component of human nutrition and a dietary source of high-quality animal proteins and amino acids. In this context, the crude protein and amino acid compositions of food fish from different landing stations of the Ganga river have been determined. The Kjeldahl method was utilized to determine the crude protein content and the amino acids were analyzed using high-performance liquid chromatography (HPLC); data on 30 food fish were assessed. The study showed that among the fish studied, Eleotris fusca, Macrobrachium malcomsonii, and Mystus cavasius were rich in most of the amino acids important for human nutrition, such as glycine, glutamic acid, cysteine, threonine, phenylalanine, methionine, lysine, leucine, isoleucine, histidine, and valine. Further, it was observed that the daily consumption of these fish (approximately 50 g) can fulfil the daily requirement of these individual amino acids for an adult human with a body weight of 60 kg. Therefore, the amino acid composition analyzed in the present study could be utilized for recommendation by clinicians according to the requirement for specific amino acids, and fish can be prescribed as a natural supplement against the amino acid requirement.
摘要:
氨基酸是控制主要代谢过程的重要生物分子,并充当大分子的前体,例如对生命至关重要的蛋白质。鱼类是人类营养不可或缺的组成部分,也是优质动物蛋白质和氨基酸的饮食来源。在这种情况下,已确定了来自恒河不同登陆站的食用鱼的粗蛋白和氨基酸组成。使用凯氏定氮法测定粗蛋白含量,并使用高效液相色谱(HPLC)分析氨基酸;评估了30条食用鱼的数据。研究表明,在研究的鱼类中,EleotrisFusca,马尔科氏沼虾,和木耳富含大多数对人体营养重要的氨基酸,比如甘氨酸,谷氨酸,半胱氨酸,苏氨酸,苯丙氨酸,蛋氨酸,赖氨酸,亮氨酸,异亮氨酸,组氨酸,还有缬氨酸.Further,据观察,对于体重为60kg的成年人,每日食用这些鱼(约50g)可以满足这些单独氨基酸的每日需求。因此,本研究分析的氨基酸组成可供临床医生根据对特定氨基酸的要求进行推荐,和鱼可以规定作为天然补充氨基酸的要求。
