解释了该类配合物的羧基红外振动峰是一宽峰且有劈裂的特点。
红外色谱分析表明：在大豆肽与钙的螯合试验中，氨基与羧基均参与了螯合反应。
氨基酸之所以叫“氨基酸”，是因为每个氨基酸分子包含一个氨基（NH2）和一个羧基（COOH）。
1·In the meanwhile, the various. morphology of the latex and the migration of the carboxyl group are also discussed.
这一反应还伴随着羧基的迁移以及乳胶粒膨润、 溶胀和压缩的形态变化过程。
2·Small molecules that can be polymerized to form proteins. Name derives from the presence of an amino group as well as an acidic carboxyl group.
能聚合形成蛋白质的小分子。名称来自于它们所带的氨基以及酸性的羧基。
3·Another end for the hydroxyl and the carboxyl group, has the water affinity.
另一端为羟基和羧基，具有亲水性。
4·The changes of intrinsic viscosity and end carboxyl group content with temperature and time were studied for poly(trimethylene terephthalate)(PTT), PET and CDP.
研究了聚对苯二甲酸丙二醇酯（ PTT） ， PET ，C DP在不同温度和时间下的特性粘数和端羧基含量的变化。
