Description
L-Proline is a cyclic α-imino acid, neutral in nature, with an isoelectric point of 6.30. It exhibits high solubility in water, surpassing that of any other amino acid, and has a sweet taste. Within a peptide chain, proline can undergo hydroxylation to form 4-hydroxyproline, a key component of animal collagen. Hydroxyproline is also found in various plant proteins, particularly those related to cell wall formation. L-Proline often accumulates in plants under stress conditions such as drought or high temperature. The product is a colorless to white crystal or crystalline powder. Purchasers should consider its high solubility, stability, and role in forming protein structures. Full documentation confirming purity and compliance with standards is available.
