Glycine CAS#56-40-6

Smallest and Simplest Amino Acid Structure: Glycine has the smallest molecular size among all proteinogenic amino acids, allowing it to fit easily into tight spaces within protein structures and contribute to molecular flexibility.


Excellent Compatibility with Diverse Environments: Due to its minimal side chain consisting of only one hydrogen atom, glycine can adapt well to both hydrophilic and hydrophobic environments, enhancing its versatility in biological and industrial applications.


Non-Chiral and Structurally Unique: Unlike most amino acids, glycine is not chiral, giving it distinctive chemical and biological behavior that is valuable in protein synthesis and formulation stability.


High Purity, Mild Taste, and Broad Applicability: As a colorless, sweet-tasting crystalline solid, glycine is suitable for use in food, pharmaceutical, and biochemical applications where purity, safety, and neutral sensory properties are important.

Product Description

Products Description of Glycine CAS#56-40-6

Glycine (Gly/G, NH₂CH₂COOH) is the smallest proteinogenic amino acid, encoded by four codons (GGU/GGC/GGA/GGG). A non-chiral, sweet-tasting colorless crystal, it functions in both hydrophilic and hydrophobic environments. Glycine is also the genus name for soybeans (Glycine max).


Product Applications of Glycine CAS#56-40-6

U.S. glycine is mainly sold as USP grade (80–85% market share) and technical grade. A higher-purity pharmaceutical grade exists for intravenous applications, exceeding USP standards and priced at a premium.

FAQ

Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.


Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.


Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.


Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
