The Role And Function Of Amino Acids In Plants

Amino acids can be formed into L and D forms, but only L-type amino acids can be used by cells. If the NH2 group is on the right side of the amino acid structure, it will be called type D and if it is on the left side of the structure, it will be called L type. Only L-type amino acids are used in protein biosynthesis.

The function of the amino acids in plants is almost endless and various aspects of them are constantly being discovered. Here are some of the most important ones:

Increased production of chlorophyll
Providing a rich source of organic nitrogen
Stimulate the synthesis of vitamins
Impact on many enzymatic systems
Flowering stimulation
Improve fruit formation
Increase the amount of food, taste, size and color of fruit
Increasing the quality of agricultural products
Increased resistance in plants

Protein Biosynthesis

Amino acids are the basic structure of proteins. Standard amino acids are highly variable fused together to produce proteins. These proteins are essential for many of the components of plant tissue.
Proteins have many different functions, such as: structural, metabolic, elemental transfer, and amino acid storage.
In fact, proteins are used in almost every biological process.
Plants produce their own proteins depending on the growth stage they are in, the elements they need, stresses, and so on.
Plants can only produce the proteins they need when their raw materials are available. Amino acid production is a process where a lot of energy is consumed.
Therefore, providing the L-type amino acids through the roots or leaves of the plant ensures that it has sufficient ingredients to make these important proteins.

Resistance to a variety of environmental stresses

Stresses such as high or low temperatures, droughts, floods, pests and diseases, or the chemical-induced effects of chemicals have a negative impact on plant metabolism, which in turn reduces plant quality and performance. Using amino acid supplements before, after, and during stress conditions can create a structure in the plant that will directly prevent and treat the complication.
When the plant is under stress, the production of amino acids slows down due to high energy consumption, and instead of producing amino acids, breaks down existing proteins to provide the amino acids it needs. This will consume less energy. This means the plant can kill itself until the amino acid it needs is supplied.
Plants increase L-proline production during stress to reduce the impact of stress and accelerate recovery time.


Photosynthesis is the most important chemical process in the plant. Carbon dioxide, water and light give the plant the energy it needs to synthesize sugars. Sugars are then used in the plant as an energy source for other metabolic processes. These yard actions are influenced by amino acids.
L-glycine and L-glutamic acid are essential metabolites for chlorophyll synthesis and tissue formation. These amino acids increase the concentration of chlorophyll in the plant. More chlorophyll means more absorption of light and consequently increased photosynthesis.

Sustainable Sources of Organic Nitrogen

The most common forms of nitrogen used by plants are nitrate and ammonium. But there is another form of nitrogen that has received less attention. This may be the reason why more research is needed on this source of nitrogen. Organic matter (such as amino acids) contains organic nitrogen and when it enters the plant its organic nitrogen is released and used by the plant.
Since part of the nitrogen that is introduced into the plant is used to synthesize protein and amino acids, the plant will need less nitrate and ammonium to prepare the form. Why is this important? Because consuming too much of everything will have detrimental consequences.
Excessive nitrate consumption leads to rapid growth and cell elongation. As cells grow rapidly, the cell wall becomes stretched and thinner. This weak tissue is a great target for plant pests. This can be seen in many plants as the plant grows rapidly but eventually the plant is weak. The excessive amount of nitrate also has antagonistic effects on the uptake of other elements such as calcium, magnesium and potassium. If nitrate is balanced and organic nitrogen is used, the cells will grow more naturally and take on a firmer structure, resulting in a stronger plant and more resistant cells.
