144-98-9 - Introduction
DL-isoleucine (DL-Isoleucine) is a natural amino acid, due to its chirality, there are two enantiomers, D-isoleucine and L-isoleucine.
Nature:
DL-Isoleucine is a white crystalline solid, odorless. Its chemical formula is C6H13NO2 and its relative molecular mass is 131.18. Its solubility is good, soluble in water and alcohol.
Use:
DL-isoleucine is widely used in food, health care products, medicine and cosmetics. It is one of the essential amino acids needed by the human body, which can enhance immunity, maintain normal physiological functions, and help muscle growth and recovery.
Method:
DL-isoleucine can be obtained by hydrolysis of natural L-isoleucine with strong acid or alkali. First, L-isoleucine undergoes a hydrolysis reaction to form DL-isoleucine, and then pure DL-isoleucine crystals are obtained through the process steps of crystallization, filtration and drying.
Safety Information:
DL-isoleucine is less harmful to human body, and its safety is higher. However, excessive intake may cause gastrointestinal reactions such as diarrhea, nausea and vomiting in some people. Therefore, when using DL-isoleucine, you should follow the appropriate dosage and method of use, and follow the recommendations of a doctor or professional.
