介绍了以氨基酸为原料生产的二肽甜味剂阿斯巴甜、阿力甜和乐甜的研究开发情况，对这三种甜味剂的应用和市场情况作了概述。

In addition,erythritol can strengthen the functionai concept since it is noncaloric,noncariogenic,and nonglycemic,and it has antioxidant properties. to be good on the international market.

和其他甜味剂同时使用可以起到协同增效作用，此外，它还是一种无热、不龋齿、不会引起血糖反应、抗氧化的甜味剂，目前在国际市场上很是看好。

The origin, chemical structure, physiological function and sweetness response of 8 kinds of functional sweetening agents including L-sugar, erythritol, and dihydrochalcone etc. were introduced briefly in this paper and their utilization in food industry, in medicine and sanitation etc. were also illustrated.

简要介绍了L-糖、异麦芽酮糖、赤藓糖醇、二氢查尔酮、阿力甜、索马甜、三氯蔗糖、人工合成甜味剂8种功能性甜味剂来源、化学结构、生理功能、甜味特性及在食品、医药卫生等方面的重要应用。

Groups with a nonsugar tradition of infant feeding show the usual strong preference for sweet dietary items after they are introduced, suggesting that a sweet preference is unlearned.

而幼儿时期有无糖喂养传统的组群在引入糖类食品后，幼儿表现出了通常的对甜味食品的强烈的偏好，这种对甜味的偏好是天然形成的。

The advance research of international and domestic natural sweetness inhibitor were summarized, mainly focused on the components and functions of three plants:Gymnema Sylvestre, Ziziphus jujuba and Hovenia dulcis Thunb.

对国内外天然甜味抑制剂的研究进展进行了综述，重点对含有天然甜味抑制成分的 3种植物———匙羹藤、大枣和枳橘的甜味抑制成分及其作用进行了阐述，为进一步研究和开发利用天然甜味抑制剂提供参考。

This study is design and preparation of active peptide analogues of mung bean trypsin inhibitor Lys fragment, Trichosanthes trypsin inhibitor I, carcinoembryonic antigen peptide and aspartame using solid and liquid phase peptide synthesis methods.

本论文研究活性多肽类似物的设计、制备和功能，分为四个部分，采用多肽固相和液相合成的方法，分别合成了活性多肽绿豆胰蛋白酶抑制剂 Lys片段长链16肽、天花粉胰蛋白酶抑制剂、癌胚抗原肽、甜味肽等一系列类似物，并测定了这些类似物的生物活性，有以下新的研究结果：1、furin酶抑制剂的设计、制备和功能；2、芳香氨基酸芳环之间的π-π共轭能部分补偿二硫键的作用；3、癌胚抗原肽Gly4被L-Pro替代可增加与HLA-A2分子的结合；4、肽键对甜味肽保持甜味是必须的。

The effect of adaptation to bitter substances (e.g., caffeine, quinine) can elicit or potentiate a sweet taste from water; adaptation to sweet substances (sucrose, fructose, and saccharin) results in a sour and bitter taste from water; adaptation to salts potentiates sour, sweet, and some bitter water tastes; and a sour adapting solution (e.g., citric acid) can produce a sweet water taste.

对苦味物质的适应影响可以引起或加强水的甜味。甜味物质的适应会引发水中的酸味和苦味。对咸味的适应会让水尝起来有酸味，甜味和一些苦味。对酸味的适应会让水尝起来甜。

Highly active, small-molecule furin inhibitors are attractive drug candidates to fend off bacterial exotoxins and viral infection. Based on the 22-residue, active Lys fragment of the mung bean trypsin inhibitor, a series of furin inhibitors were designed and synthesized, and their inhibitory activity toward furin and kexin was evaluated using enzyme kinetic analysis. The most potent inhibitor, containing 16 amino acid residues with a Ki value of 2.45×10~(-9) M for furin and of 5.60×10~(-7) M for kexin, was designed by three incremental approaches.

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
