5-aminolevulinic acid (5-ALA), γ-aminobutyric acid, and γ-polyglutamic acid are frequently encountered in various products. Let’s delve into the applications of these fertilizer additives.
1. 5-Aminolevulinic Acid(5-ALA)
5-ALA is actually an amino acid but does not take part in protein synthesis. It is a non-protein amino acid and not as mysterious as it may seem. It is a natural amino acid, not artificial in origin. Found commonly in animals and plants, it is widely used in medicine, cosmetics, animal husbandry, and planting. Initially, due to production capacity limitations, it may have been more utilized in medicine and cosmetics. However, with the development of synthetic biology, production capacity has significantly increased, enabling its gradual application in agriculture. In agriculture, 5-ALA has several main functions, including promoting photosynthesis, enhancing crop resistance, and facilitating fruit color change. At the same time, attention must be paid to the dosage, as a high concentration can turn it into a herbicide.
2. γ-Aminobutyric Acid
γ-aminobutyric acid, like 5-ALA, is also a non-protein amino acid and a natural amino acid found in animals and plants. Widely used in medicine, cosmetics, animal husbandry, and planting, it mainly plays a role in promoting growth and resisting stress in agriculture.
Polyglutamic acid (γ-PGA) has one more “poly” than glutamic acid. What does “poly” mean? It indicates aggregating multiple glutamic acids together to form a chain, which is polyglutamic acid. It might seem familiar. In fact, it is a peptide chain. Ordinary peptide chains have at least two or more amino acids, while polyglutamic acid consists of only one amino acid, glutamic acid. This kind of peptide chain with only one amino acid is called a polymerized amino acid.
When it comes to enhancing agricultural productivity and soil health, organic fertilizers play a crucial role. Organic fertilizers （See what is organic fertilizers） provide a natural source of nutrients and improve the structure of the soil, promoting better root growth and overall plant health. They are sustainable and environmentally friendly, ensuring long-term benefits for both the crops and the ecosystem. Consider incorporating organic fertilizers into your agricultural practices for optimal results.
