L-serine

1. ProductAttributes

L-serine (CAS number: 56-45-1) produced by HuaYuanShengKe is a

naturally occurring neutral amino acid with the molecular formula

C3 H7 NO3, molecular weight 105.09, white crystalline powder or

prismatic crystal, odorless and sweet. Its solubility is high (up to 250g/L aqueous solution at 20 °C), soluble in water and formic acid, almost

insoluble in ethanol and ether, and the isoelectric point is 5.68. The

product meets the food grade standard and is suitable for many fields such as food, medicine, cosmetics and so on.

2. Fieldsof application

Food additives: As a nutritional enhancer, it can improve the utilization rate of food protein and improve the flavor (such as the flavor of maple syrup after heating with glucose), especially suitable for meat products, beverages, bakery products, etc

Pharmaceutical field: used for compound amino acid infusion,

nutritional supplement, and as a precursor for the synthesis of

anticancer agents and antibiotics (such as cycloserine), which plays an important role in metabolic balance and immune regulation

Cosmetics: As a natural moisturizing factor ingredient, it has hydrating and anti-aging functions, and is often used in high-end skin care

products

Feed industry: promote animal growth, improve feed protein   utilization, reduce nitrogen emissions, and meet environmental protection requirements

3. Productionprocess and technical advantages

HuaYuanShengKe uses microbial fermentation to produce L-serine, relying on its core technology of biological fermentation and

independent research and development capabilities

Fermentation process: Modify strains (such as Escherichia coli or

Corynebacterium glutamicum) through metabolic engineering

technology to optimizeserine hydroxymethyltransferase activity and achieve efficient transformation

Quality control: Comply with ISO 9001, ISO 22000, HACCP and other

international certifications to ensure product purity (≥98.5%) and safety

4. ProductSpecifications and Packaging

Packing specification: 25 kg/bag (plastic woven bag),inline with industrial and commercial batch requirements

Storage conditions: It is recommended to store in a ventilated, cool, low-temperature and dry place, and the shelf life is 2 years

5. Marketcompetitiveness

As the world’s leading amino acid manufacturer, HuaYuanShengKe

provides cost-effective L-serine by virtue of its large-scale production  advantages (annual production capacity covers a variety of amino acid derivatives) and the layout of the whole industry chain to meet the

differentiated needs of domestic and foreign customers for food-grade and pharmaceutical-grade products
