Certain amino acids such as histidine, cysteine, serine and threonine are structurally fragile. At room temperature, activation can flip their chiral center, a side reaction called racemization. The result is an optical isomer that looks almost like your target peptide but is useless, and it is a pain to remove later. For anyone making high-purity or API-grade peptides, racemization is the silent tax on yield and purity: it shows up as a low qualification rate, and every failed batch means rework, wasted resin, and slipped timelines.
