The Effect Of Betaine
May 05, 2018

As a feed additive, it has the function of providing methyl donor, which can save some methionine. It has the function of regulating body osmotic pressure, alleviating stress, promoting fat metabolism and protein synthesis, improving the function of lean meat rate, and enhancing the efficacy of anti-coccidiasis. Used as a food attractant in aquatic animal feed.


Maintain cell osmotic pressure: when affected by salinity and water stress, the cytoplasm in the accumulation of a large number of organic osmotic regulators such as betaine, and inorganic osmotic regulator in the cytoplasm is mainly used to vacuole, the cytoplasm and cell vacuole) external environment maintaining osmotic balance, so to avoid the poison of the cytoplasm of enzymes and inorganic ions with high metabolism. The accumulation of betaine in plants under salt stress is an important physiological phenomenon that is beneficial to the growth of plants under stress, and its content is positively correlated with plant salt tolerance.


Protective effect of enzyme: betaine has high solubility, without electrostatic charge, and its high concentration has no effect on many enzymes and other biological macromolecules, and even has protective effect. Betaine can protect the cell membrane of beet, prevent heat damage, and improve the temperature of the enzyme thermal denaturation. It can protect the spinach thylakoid membrane against freeze stress. The toxicity of high concentration salt to enzyme activity; To prevent hydrothermal disturbance induced by dehydration; It also has good protective effect on aerobic respiration and energy metabolism. Betaine has a stabilizing effect on peripheral skin of PSH.


Resistance to salt: betaine can rapidly synthesize and accumulate to a high concentration in the body, and it has no feedback inhibition in the biosynthesis reaction and produces NAOH. Betaine is the best osmotic regulator in over 150 metabolites studied, and the low concentration of exogenous betaine has a good effect. If the culture medium contains o8m (the growth of escherichia coli is completely stopped, but 10 Yang lo), the growth is completely restored. When the stress was relieved, the content of proline in leaf and root decreased immediately, while the content of betaine was basically stable. This indicates that the accumulation of proline is a temporary reaction to stress, while the accumulation of betaine may be permanent or semi-permanent. The characteristics of the slow metabolism of betaine showed that the metabolism regulation of betaine was mainly determined by synthesis.


The distribution of inorganic ions: barley can accumulate betaine under salt stress. Compared to garoon et al., when studying mangrove plants that accumulate betaine, the betaine can be transported by betaine/P roline transport. Yale by applying exogenous betaine to observe such as barley mitigation effect of salt stress, the results showed that betaine can reduce the degree of membrane lipid peroxidation, water content and raise barley seedlings under salt stress root fresh weight of seedlings. The Na water ratio in the root system can be significantly reduced by betaine treatment. In the leaves, the roots are to the phoenix! A large number of interception, make lm (xi several betaine treatment leaves of the phoenix! The solution ratio is significantly lower than the salt treatment. Betaine can retain ca2 + interception in the root system, which may be important for root resistance to salt damage. In addition, betaine has certain regulatory effects on stomatal movement, respiration and related gene expression in adverse conditions.
