L- and D-amino acids are essential organic compounds that serve as the building blocks of proteins. They are characterized by their chiral nature, meaning they exist in two mirror-image forms: L (levo) and D (dextro). These amino acids can be synthesized from various raw materials through chemical processes or extracted from natural sources. They are widely used in pharmaceuticals, biotechnology, and nutritional supplements due to their critical role in biological processes and metabolic functions.
| Purity | Typically 98% or higher |
| Form | Powder or crystalline form |
| Solubility | Soluble in water, varying by amino acid |
| Storage conditions | Cool, dry place, away from light |
| Shelf life | Typically 2-3 years when stored properly |
When selecting L- and D-amino acids, buyers should consider the required purity levels and specific forms needed for their applications. It is important to specify whether L or D forms are needed, as well as any relevant grades or certifications, such as GMP compliance for pharmaceutical use. Quantities can vary significantly, so buyers should clearly communicate their needs to ensure appropriate supply.
