Protein is divided into plant protein and animal protein. After protein is decomposed, amino acids are formed, which is what we call plant-derived amino acids and animal-derived amino acids. People often ask whether plant-derived amino acids or animal-derived amino acids are better. There have been many disputes over this issue, and each has its own reasons. In fact, no matter which source of amino acids, there is no difference between good and bad. This question is like asking people whether it is better to eat meat, fish, or soy. Why do people eat whole grains, fish, and meat, and why they need a balanced diet to be healthy? It is because different foods have different amino acid composition ratios. The 20 basic amino acids cannot be comprehensively covered by a certain food, or It is impossible to balance. Different amino acids have their own effects on the human body. The same is true for plants. The composition of amino acids from different sources is different, and the effects on the physiological functions of plants are also different.
People can crush protein foods through teeth, and then enter the intestines and stomach. After digestion by gastric acid and intestinal pancreatic enzymes, the protein is broken down into polypeptides, oligopeptides, small peptides, free amino acids, etc. for absorption. However, plants do not have these decomposition functions and can only be artificially decomposed and supplemented by leaves or roots. Although plants can synthesize various amino acids needed by themselves, they are affected by various adversities such as bad weather, diseases and insect pests, and phytotoxicity. The synthesis of amino acids is limited or the synthesis function is weakened, and it is necessary to adjust the plant to achieve various physiological balances through the supplementation of exogenous roots or leaves, so as to promote plant growth to the best state. This is also why we use amino acid biostimulants. purpose.
Common sources of plant-derived amino acids are soybeans, wheat, oats, corn, etc. The sources of animal-derived protein are relatively wide. Animal hair (feathers, bristles, etc.), silkworm pupae, animal blood, internal organs, skin and bones, low-value fish, etc. Hydrolyzed into usable amino acids, the proportion of amino acids contained in the same plant source is also very different, and the same is true for the animal source. For example, hydrolyzed animal hair contains higher levels of cystine and serine, hydrolyzed animal skin and bones contain higher levels of glycine and proline, animal blood contains higher levels of leucine and phenylalanine, and corn and wheat contain higher levels. Glutamate is higher.
Amino acids from different sources have different effects on crops due to the different composition ratios of amino acids. If you need to improve the stress resistance of crops, amino acids derived from animal skin and bones with higher proline and glycine are the best choice. If you want to increase the lignification of plants, control shoots, and increase anthocyanins, then contain phenylpropanine Amino acids derived from animal blood with higher amino acids are a better choice. If it is green leaves and promotes growth, then plant-based amino acid raw materials such as wheat and corn with higher glutamate are effective. Therefore, plant-derived amino acids and animal-derived amino acids are not good or bad. Only by focusing on their characteristics can they play a better role.
