In chapter 2,the bi-electrophilicity ofα-CAPAs(Gly-CAPA,Ala-CAPA) was identified by the isotope analysis ~(18O,~(15)N and furtherproved by trappingα-CAPA with nucleophiles such as water,amino acids,phosphateand methanol in alkaline media which yielded phosphorylated products,namely,theNPAAs and N-(mono-substituted)phosphoryl amino acids.

自CAPA的结构被提出以来，CAPAs的化学反应几乎没有得到进一步的研究，所以本论文的第二章研究了以甘氨酸-CAPA和丙氨酸-CAPA为代表α-CAPAs分子，通过同位素标记实验~(18O，~(15)N证明了CAPA分子具有两个亲电中心。

同时，CAPA和亲核试剂如水，氨基酸，磷酸和甲醇分子反应可以生成各种磷酰化产物，如NPAAs和N-磷上单取代的磷酰化氨基酸。

To compare the digestibility of amino acid in plant feedstuffs between cockerel and drake,48 Hy-Line Brown cockerels and 48 Peking drakes in 18 weeks with similar weight(2.6±0.20) kg were employed to bioassay amino acid digestibility of 7 feedstuffs,including paddy,corn,wheat,wheat bran,soybean meal,cottonseed meal and peanut meal.

本文旨在研究鸡和鸭对饲料氨基酸消化率的差异，为合理配制鸭饲料提供必要参考。选用18周龄健康、体重约为(2.6±0.20)kg的海兰褐佳蛋公鸡和北京Z系公鸭各48只。

Pparent amino acid digestibilities and true amino acid digestibilities of six feedstuffs (barley,cooking blood meal,fermented blood meal,protein hydrolysate mixed feed,heatextruded collagen protein and local fish meal) and their mixed feeds(J1 and J2) were determined with intact and caecectomized cockerels,using Sibbaled "TME" method,and their additivities were also tested.

本研究以去盲肠鸡和正常鸡按Sibbald的&TME&方法分别测定了皮大麦、蒸煮血粉、发酵血粉、水解复合蛋白、热喷胶原蛋白、国产鱼粉及其配合饲料J1和J2的氨基酸表观消化率和真消化率。并对两种试鸡所测上述饲料原料氨基酸的消化率及其可加性作比较。结果表明：（1）6种饲料原料的某些氨基酸表观消化率和真消化率，去盲肠鸡和正常鸡测值间存在显著差异（P＜0.05）。（2）去盲肠鸡内源氨基酸排出量显著高于正常鸡（P＜0.05）。

But, with more codons than amino acids, many amino acids have more than one codon to describe them.

由于基码的数量比氨基酸多，许多氨基酸有超过一个基码来表述它们。

Sequences were aligned by BLAST method. Results showed that 309bp fragments shared high similarity with orfl38 in Ogu CMS radish and Brassica cybrids of Ogu CMS radish, which 172 nucleotide sequences and 58 amino acids were same among them. And 689bp fragments shared high similarity (100%) with Pol orf224 in B.napus, which 677 nucleotide sequences and 225 amino acids were same among them.

Music alcohol mechanism of anti-fatigue: Nano-peptide can promote aerobic metabolism, the rapid removal of excess lactic acid in muscles, faster removal of fatigue; when fatigue or liver disease, the other blocked amino acid metabolism, and branched-chain amino acids in muscle tissue can be metabolism, provide energy as the material, nano-peptide can be slowed down muscle protein breakdown and damage the body to ease the friction, and added the supply of glycogen after exercise, play the role of anti-fatigue.

酒乐的抗疲劳机理：纳米肽可促进有氧代谢，迅速清除肌肉中过多的乳酸，较快清除疲劳；当肝脏疲劳或病变时，其它氨基酸代谢受阻，而支链氨基酸可在肌肉组织中代谢，作为提供能量的物质，纳米肽可减缓肌肉蛋白的分解和肌体损伤，缓解内耗，并补充运动后糖原的供给，起到抗疲劳的作用。
