牛科动物黄牛的皮长时间水煮，则皮中的胶原变化而成黄明胶。牛皮的胶原含氮18.6%，也含一些糖，其总量105g中含有氨基酸分子数是：甘氨酸363，丙氨酸107，缬氨酸29，亮氨酸+异亮氨酸43，脯氨酸131，羟基脯氨酸107，苯丙氨酸15，酪氨酸5，丝氨酸32，苏氨酸19，蛋氨酸5，精氨酸49，组氨酸5，赖氨酸31，羟基赖氨酸7，天冬氨酸47，谷氨酸77。变化为黄明胶后，含氮为18.0%，其105g中氨基酸分子数是：甘氨酸359，丙氨酸105，缬氨酸28，亮氨酸26，异亮氨酸14，脯氨酸129，羟基脯氨酸111，苯丙氨酸15，酪氨酸6，丝氨酸30，苏氨酸19，蛋氨酸6，精氨酸49，组氨酸5，赖氨酸32，羟基赖氨酸7，天冬氨酸51，谷氨酸76，与上文对照，可见胶原与明胶组成上也略变动，但两者都不含胱氨酸、半胱氨酸是其特点。性质上的显著差异是胶原不溶于水，明胶能溶于水。明胶也含少量的钙，主要是在制胶过程中用石灰脱脂时掺入的。药理作用
If the skin of cattle, such as the yellow cattle, is boiled in water for a long time, the collagen in the skin will change and become gelatin. The collagen in the cowhide contains 18.6% nitrogen and some sugars. In a total of 105g, the number of amino acid molecules is as follows: glycine 363, alanine 107, valine 29, leucine + isoleucine 43, proline 131, hydroxyproline 107, phenylalanine 15, tyrosine 5, serine 32, threonine 19, methionine 5, arginine 49, histidine 5, lysine 31, hydroxylysine 7, aspartic acid 47, glutamic acid 77. After the change to gelatin, the nitrogen content is 18.0%, and the number of amino acid molecules in 105g is: glycine 359, alanine 105, valine 28, leucine 26, isoleucine 14, proline 129, hydroxyproline 111, phenylalanine 15, tyrosine 6, serine 30, threonine 19, methionine 6, arginine 49, histidine 5, lysine 32, hydroxylysine 7, aspartic acid 51, glutamic acid 76. Comparing with the previous text, it can be seen that there are slight changes in the composition of collagen and gelatin, but both do not contain cysteine and half-cysteine, which is their characteristic. The significant difference in properties is that collagen is insoluble in water, while gelatin can dissolve in water. Gelatin also contains a small amount of calcium, mainly added during the degreasing process with lime in the gelatin production. Pharmacological effects.

20%黄明胶液0.5ml只给小鼠灌胃，每日1次，连续11d，使血红蛋白量明显增加，表明有补血作用；小鼠白细胞数虽有增加，但不显著。按上法给药15d，稍能延长小鼠游泳时间，有一定抗疲劳作用；此外对小鼠胸腺有一定增重作用。牛皮尚可用于制取胶原，胶原对乙醇所致大鼠胃粘膜损害有促进修复和保护作用。相关论述
20% gelatin solution 0.5ml was administered to mice by gavage once daily for 11 consecutive days, resulting in a significant increase in hemoglobin levels, indicating a blood-nourishing effect. Although the white blood cell count in mice increased, the change was not significant. Administering the drug according to the above method for 15 days slightly extended the swimming time of the mice, showing a certain anti-fatigue effect. Additionally, it had a certain effect on increasing the thymus weight in mice. Bovine hide can still be used to extract collagen, which has a promoting repair and protective effect on ethanol-induced gastric mucosal damage in rats. This is the relevant discussion.

The dried yellow oxhide is cut into small cubes, soaked in clean water for 2 days, and stirred and water changed frequently until the oxhide becomes soft. Then it is washed and removed, placed in a copper pot, and approximately 5 times the amount of clean water is added. Heat it slowly to boiling, adding water as needed. Every 24 hours, filter the clear liquid, repeating this process 3 times. Use alum to precipitate all the filtrate, pour off the clear juice, then heat and concentrate it in the copper pot until it does not dissolve when dropped onto filter paper. Add auxiliary ingredients such as yellow wine or rock sugar to make it into a gel, pour it into a gel plate, let it cool, cut it into small pieces, and air dry.Identification of Medicinal Materials: Characteristics of Medicinal Materials
