The entire synthesis process can be summarized into several key steps, as shown in Figure preparation process Solid phase synthesis: Using Wang Resin (1.0 mmol/g), S=0.3 mmol/g, and employing Fmoc process. First connect Fmoc Cys (Trt) - OH Wang resin. Then, according to the above peptide sequence, the amino acids are sequentially condensed from the C-terminus to the N-terminus (from right to left) until the resin peptide is obtained.

Active peptides are important active substances in the human body, mainly distributed in nerve tissues and other organs, which can ensure normal cell division and protein synthesis. Once an error occurs in cell division, the active peptide will command the erroneous cell to stop replicating and repair it, thereby ensuring the normal synthesis of proteins. Proteins are the basic elements that make up human cells, as well as the components that make up white blood cells and antibodies. They have the function of promoting growth and development, bone development, and immune function, so peptides can maintain normal physiological functions.
