Product Overview

Yeast Nucleotide Peptide by LYS (Long Yeast Science) is a cutting-edge biostimulant derived from enzymatically hydrolyzed yeast protein. It is designed to enhance plant metabolism, stress resistance, and nutrient uptake. The formula is rich in short-chain peptides, nucleotides, and free amino acids—making it a powerful natural crop enhancer.

Key Active Components of Yeast Nucleotide Peptide

•Yeast Peptides (≥260g/L)

Produced through FSDT full-spectrum directional enzymatic hydrolysis, over 87.42% of the peptides are ≤1000 Da, ensuring high bioavailability. These peptides are rich in 18 amino acids such as arginine and lysine, directly participating in plant metabolic processes.

•Nucleotides (≥30g/L)

Includes bases like adenine and guanine, which regulate cell division and activate stress-response genes such as DREB (for drought resistance) and CBF (for cold resistance).

•Free Amino Acids (≥240g/L)

Primarily glycine and proline, which play dual roles in nutrient supply and signal transduction. Proline, for example, enhances osmotic regulation in cells under abiotic stress.

Synergistic Transport Mechanism

Peptides form hydrogen bonds with nucleotides to create stable peptide-nucleotide complexes. This enhances transport efficiency by 2.3x and extends nucleotide half-life from 4 to 12 hours, resulting in longer-lasting biological activity

Functions of Yeast Nucleotide Peptide

1. Cellular Regulation and Metabolism

Accelerated Cell Division

Nucleotides promote DNA synthesis during the S-phase, shortening the G1 phase by 20%. In corn root tips, the mitotic index increases by 28%.

Enzyme Activation

Peptides bind with glutamate dehydrogenase, increasing its activity by 40%, while nitrate reductase activity in wheat leaves rises by 25%.

2. Stress Resistance and Defense

Oxidative Stress Reduction

Yeast peptides neutralize superoxide anions. In rice under cold stress, MDA levels decrease by 34% and SOD activity increases by 56%.

Cell Wall Strengthening

Nucleotides induce PAL enzyme activity (+60%), improving rice stem strength by 22%, which helps prevent lodging.

3. Nutrient Uptake and Root Development

Root Architecture Remodeling

Free amino acids stimulate root hair proliferation. In potted tomatoes, root hair count increases by 41% and root surface area expands by 58%.

Micronutrient Chelation

Short-chain peptides chelate trace elements like zinc (logK≥15), raising zinc uptake efficiency in citrus leaves from 12% to 35%.

Distinct Advantages of Yeast Nucleotide Peptide

1. High Molecular Stability

•Peptides ≤1000 Da remain stable across pH 4–10 and chelate metal ions effectively (e.g., Zn-peptide Kd ≤ 10⁻⁸ M).

•Compatible with various formulations: soluble powder, liquid concentrate, and EC.

•Maintains clarity in high-concentration drone spraying mixtures (30x dilution), with no precipitation or layering.

2. Excellent Compatibility with Other Biostimulants

•Naturally sourced from yeast fermentation, this product is highly compatible with humic acids, seaweed polysaccharides, and microbial metabolites.

•Forms stable hydrogen-bonded complexes when mixed with humic acid, improving soil retention and boosting nutrient utilization by 20%.

3. Ultra-Pure Composition, Free from Inert Fillers

•Produced via triple membrane filtration (ultrafiltration + nanofiltration) to remove salts, heavy metals (Pb ≤ 1.0mg/kg, As ≤ 0.05mg/kg), and macromolecules.

•Final chloride content ≤1.0g/L (far below the NY/T 1429-2010 limit of 30g/L).

•Environmentally safe: no synthetic hormones, fast degradation in soil (half-life ≤7 days), compliant with EU REACH and China organic input standards.
