Bulk L-leucine Powder

What is leucine?

L-Leucine is a branched-chain amino acid, chemically known as 2-amino-4-methylvaleric acid. As the most metabolically active member of the branched-chain amino acids, L-leucine directly initiates skeletal muscle protein synthesis by activating the mTOR signaling pathway, making it a crucial regulator in muscle protein synthesis. Under calorie restriction, adequate leucine intake helps maintain net muscle mass, prevent muscle loss, and improve post-exercise tissue repair and endurance performance.

YTBIO supplies L-leucine with 99% purity, excellent batch-to-batch stability, suitable for sports nutrition, weight-loss meal replacements, and medical nutrition formulations. It has complete certifications, supports customized packaging, and samples are welcome for testing.

What are the benefits?

1. Oxidation energy supply

Leucine can be used for protein synthesis in the body, but it can also be used as an energy source during special physiological periods (hunger, lactation, stress and exercise, etc.). When piglets are hungry, the amount of leucine oxidized in their brains and muscles increases. Ruminal protozoa can also use BCAA as an energy source. BCAA can be transaminated and completely oxidized at a faster rate. The efficiency of oxidation to produce adenosine triphosphate (ATP) is higher than that of other amino acids. The complete oxidation of each molecule of leucine, isoleucine and valine produces 42, 43 and 32 molecules respectively. ATP. Its main metabolic site is in muscle. Under the action of transaminases, BCAA transfers the amino group to ketoglutarate to generate glutamate, and glutamic acid transfers the amino group to pyruvate to generate alanine. Under special conditions, the utilization rate of the two gluconeogenic amino acids is increased, and the energy conversion of hepatic gluconeogenesis is accelerated, which reduces the serum alanine and glutamic acid mass concentrations. BCAA supplementation can save muscle glycogen.

3. Regulate the body’s immune function

Pure leucine powder deficiency causes thymus and spleen atrophy, lymphoid tissue damage, and reduced immunoglobulin, complement C3, and ferroportin levels in animals. BCAA deficiency in weaned piglets results in a reduced ability to synthesize specific antibodies. Adding rumen protective α-KIC (0.05%) can enhance the antibody response and lymphocyte proliferation response of lambs against pig red blood cells, while adding 0.05% leucine can inhibit the production of antibodies against pig red blood cells; adding leucine to sheep feeding With α-KIC, it can regulate the immune function of its T-lymphocyte subsets. Broiler chickens supplemented with 0.6% α-KIC did not enhance their antibody response against Newcastle disease virus. The effect of leucine and its transamination products on the immune response of animals is affected by factors such as the form, quantity, and type of animal added.

Key Characteristics of Leucine and its Metabolites

An experiment revealed the core regulatory role of the leucine-metabolizing enzyme AUH (enoyl-CoA hydratase) in lipid thermogenesis, indirectly demonstrating the following characteristics of leucine and its metabolites:

The leucine-metabolizing enzyme AUH not only participates in the catabolism of leucine (generating HMG-CoA), but also possesses a non-metabolic function—RNA-binding activity. This indicates that the leucine metabolic pathway can both generate metabolite signals (HMG-CoA) and directly regulate gene expression through the enzyme's additional function.

The leucine metabolic intermediate HMG-CoA can act as a modifying group, performing HMGylation on the key transcription factor PPARγ. This reveals that leucine metabolism not only provides energy/substrate but can also directly regulate protein function through covalent modification, representing a novel metabolic signaling mechanism.

AUH upregulates UCP1 expression through two parallel pathways: first, by enhancing the transcriptional activity of PPARγ through HMG-CoA; and second, by directly binding to the 3′UTR of UCP1 mRNA, increasing its stability. This indicates that leucine-metabolizing enzymes can finely regulate the expression of thermogenic genes at both the transcriptional and post-transcriptional levels.

HMG-CoA levels increased in brown adipose tissue under cold exposure, while decreased in white adipose tissue under obese conditions. This suggests that the levels of leucine metabolites are regulated by physiological and pathological conditions and can conversely affect fat thermogenesis and energy balance.

AUH expression was reduced in adipose tissue of obese individuals, and overexpression of AUH could resist obesity induced by a high-fat diet and improve insulin sensitivity. This suggests that impaired leucine metabolism may be associated with the development and progression of obesity and has potential therapeutic target value.

This experiment demonstrates that the leucine metabolic system is not only a catabolic pathway but also a multifunctional signaling network integrating energy sensing, epigenetic modification, RNA stability regulation, and intervention in metabolic diseases.

The leucine-metabolizing enzyme AUH dually regulates brown adipose thermogenesis through HMG acylation modification of PPARγ and its RNA binding function

Application direction

Bulk L-leucine Powder can be used as a nutritional supplement, flavoring and flavoring agent, and can also be used to prepare amino acid infusions and comprehensive amino acid preparations, hypoglycemic agents, and plant growth promoters.

Leucine's functions include working with isoleucine and valine to repair muscles, control blood sugar, and provide energy to body tissues. It also increases the production of growth hormone and helps burn visceral fat, which is difficult to effectively target through diet and exercise alone due to its location within the body.

Leucine, isoleucine, and valine are all branched-chain amino acids that help promote muscle recovery after training. Among them, leucine is the most effective branched-chain amino acid, which can effectively prevent muscle loss because it can be broken down and converted into glucose faster. Increasing glucose prevents damage to muscle tissue, so it is especially suitable for bodybuilders. Leucine also promotes the healing of bones, skin, and damaged muscle tissue, and doctors often recommend that patients take leucine supplements after surgery.

Because it is easily converted into glucose, leucine helps regulate blood sugar levels. People with leucine deficiency may experience symptoms similar to those of hypoglycemia, such as headaches, dizziness, fatigue, depression, confusion, and irritability.

The best food sources of leucine include brown rice, beans, meat, nuts, soy flour, and whole grains. Since it is an essential amino acid, this means that the body cannot produce it on its own and can only obtain it through diet. People who engage in high-intensity physical activity and eat a low-protein diet should consider taking a leucine supplement. Although there are stand-alone supplement forms, it’s best to take them together with isoleucine and valine. Therefore, it is more convenient to choose a hybrid supplement.
