dipeptide - Names and Identifiers
dipeptide - Introduction
A dipeptide is a compound made up of two amino acid residues joined. It has the following properties:
1. Solubility: Many dipeptide have good solubility in water and can form a solution.
2. Stability: Most dipeptide is relatively stable under neutral or acidic conditions. However, under alkaline conditions, some dipeptides may undergo hydrolysis or decomposition.
3. Amino acid sequence: the nature of dipeptide is affected by its amino acid sequence. Different amino acid combinations can lead to different chemical properties.
dipeptides play an important role in organisms. They can be used as bioactive peptides and participate in many biological processes, such as enzyme catalysis, cell signal transmission and immune regulation. In addition, dipeptide is also widely used in food, medicine and cosmetics. Some dipeptide has antioxidant, antibacterial, anti-inflammatory and anti-tumor biological activity, so it is used as food additives, drugs and skin care products.
There are two main methods for preparing dipeptide:
1. Condensation of amino acids: connect two amino acids into dipeptide through a condensation reaction. The commonly used methods are activation condensation method, DCC/HOBt method and FMOC/t-Bu method.
2. Amino acid protecting group selective substitution of amino acid: First of all, one amino acid protection of hydroxyl group, and then the other amino acid selective substitution, and then remove the protecting group, can synthesize dipeptide.
When using and handling dipeptide, follow proper safety procedures to avoid harm to humans and the environment. Note the following safety information:
1. Avoid inhalation: to prevent inhalation of dipeptide dust or steam, should be in a well-ventilated place of operation.
2. Avoid Contact: should wear laboratory protective equipment, such as gloves, goggles and laboratory clothes, to avoid skin and eye contact.
3. Storage conditions: dipeptide should be stored in a sealed container, away from high temperature, humidity and fire.
4. Waste treatment: waste dipeptide should be properly treated and disposed in accordance with local environmental regulations to avoid environmental pollution.
Please note that before using dipeptide or performing dipeptide synthesis, the specific risks and operating requirements should be evaluated according to the safety data sheet of the specific compound and the relevant chemical laboratory guidelines.
