Plant source amino acids and animal source amino acids

- Jul 25, 2019-


Proteins are divided into plant proteins and animal proteins. After decomposition, proteins form amino acids, which are plant-derived amino acids and animal-derived amino acids. Some people often ask, which is good for plant-derived amino acids and animal-derived amino acids. There have been many debates on this issue, and each has its own rationality. Actually, no matter which source of amino acids, there is no difference between good and bad, this question is like asking people to eat meat well, or to eat fish well, or to eat soy. Why do people eat all kinds of grains, fish, and meat? Why should we have a balanced diet to be healthy? It is because the proportion of amino acids in different foods is different. The 20 basic amino acids cannot be covered by a certain kind of food, or It is impossible to balance, different amino acids have their own effects on the human body (specifically, you can ask for the mother), the same is true for plants, the amino acid composition ratios of different sources are different, and the physiological functions of plants are also different.

Humans can pulverize protein foods through the teeth and then enter the stomach and intestines. After decomposition by trypsin in the stomach acid and intestinal tract, the protein is decomposed into peptides, oligopeptides, small peptides, and free amino acids for absorption. However, plants do not have these decomposing functions. They can only be artificially decomposed and then added to the foliage or roots. Although the plants themselves can synthesize various amino acids, they are affected by various adverse conditions such as adverse weather, pests and diseases, and phytotoxicity. The synthesis of amino acids is limited or the synthesis function is weakened. It is necessary to supplement the roots or the exogenous sources of leaves to regulate the physiological balance of the plants and promote the optimal growth of the plants. This is also the use of amino acid biostimulating hormones. purpose.

Common sources of plant-derived amino acids are soybean, wheat, oats, corn, etc. The source of animal-derived proteins is relatively wide. Animal hair (feathers, piglets, etc.), silkworm cocoons, animal blood, internal organs, skin bones, low-value fish, etc. can all be It is hydrolyzed into available amino acids, and the proportion of amino acids contained in plant sources is also very different, as is the source of animals. For example, hydrolyzed animal hair contains cystine and serine, and the hydrolyzed animal skin contains glycine and proline. The animal blood contains leucine and phenylalanine, while in corn and wheat. Higher in glutamate. Therefore, amino acids from different sources differ in the composition of amino acids, and the effects on crops are different. If it is necessary to improve the stress resistance of crops, amino acids derived from animal skin containing higher proline and glycine are the best choices, such as increasing lignification, controlling shoots, and increasing anthocyanins in plants. Amino acids with higher blood amino acids are better choices. If they are green leaves and promote growth, the plant amino acid materials such as wheat and corn with higher glutamic acid are more effective. Therefore, plant-derived amino acids and animal-derived amino acids are not good or bad, and only for their characteristics can they work better.
