Visual inspection of spectra shows that the differences observed in spectra of different cells in band intensities at 1603cm^(-1)(C=C in-plane bending mode of phenylalanine and tyrosine) and 1616cm^(-1)(C=C stretching mode of tyrosine and tryptophan) are obvious. This can be used as the marks for blood cell of defferent species. And LTRS is a useful tool for the blood cell analysis.

结果显示不同物种血红细胞的拉曼光谱在1603cm^(-1)苯丙氨酸和色氨酸的C=C平行振动模及1616cm^(-1)酪氨酸和色氨酸的C=C拉伸模有明显的差异，这可以用来作为不同种血红细胞鉴定的特征标记，表明激光镊子拉曼光谱技术可以成为血红细胞分析的有效手段。

MSH can cause in the melanophore the tyrosine words enhancement, causes the tyrosine the copper thing to turn the Asian copper thing, strengthens the epidermal cell to embezzle the melanin pellet, and urges the melanin pellet under the ultraviolet radiation to turn the state of oxidation from the return to original state condition, causes the skin pigmentation.

MSH能使黑色素细胞内酪氨酸话性增强，使酪氨酸的铜化物变成亚铜化物，加强表皮细胞吞没黑色素颗粒，并在紫外线照射下促使黑色素颗粒从还原状态变成氧化状态，导致皮肤色素沉着。

Erve growth factor can combine with its" receptor (one of tyrosine protein kinase receptor coded by proto - oncogene tyrosine kinase, TrkA), Causing the molecule of receptors to gather on the cell surface, and the tyrosine protein in cytoplasmic domain may be activated, three tyrosine base in the kinase domain of its" receptor and two tyrosine base at other domain be phosphated, thus, phosphated tyrosine receptor kinase became the bracket which absorb all kinds of connective proteins and kinases.

GF与其酪氨酸受体激酶受体(由原癌基因trk编码的一种酪氨酸蛋白激酶受体，TrkA)相结合，引起受体分子在细胞表面发生二聚体化，然后受体细胞内结构上酪氨酸活性被激活，使受体自身结构中位于激酶结构域的三个酪氨酸残基及在此结构域外的两个酪氨酸残基发生自身磷酸化，这样，磷酸化的酪氨酸受体激酶A便成为吸收各种连接蛋白质和酶的支架。
