This discussion compares tripeptides, exemplified by the well-studied GHK, with larger peptides such as the cyclic heptapeptide CyRL-QN15, the human cathelicidin-derived antimicrobial peptide LL-37, and the peptide Andersonin W-1 (AW1), containing 7, 37, and 72 amino acids, respectively [25, 67, 68]
Its unique gastric stability distinguishes it from other regenerative peptides
Once trapped in the spleen, the abnormal erythrocytes undergo splenic conditioning, resulting in further loss of surface area

Our data show that CTL proteins CTL1, PNS1, and CherI do not transport choline in oocytes under the conditions tested, but it cannot be discounted that these proteins might have some transport functionality under different experimental conditions
