167aminoacid

167aminoacid is a label encountered in casual discussions of protein length, referring to a polypeptide composed of 167 amino acid residues. The conventional shorthand for such a molecule is 167 aa, and many databases list entries by their length in residues rather than by descriptive labels.

In practice, 167 amino acids represent a moderate size for a protein. Polypeptides of this length can form single-domain proteins and may participate in a range of functions, from enzymatic activity to structural roles. The specific properties of a 167-residue protein—such as stability, isoelectric point, and folding pattern—depend on its amino acid sequence and overall composition.

Because 167aminoacid is not a formal term in standard nomenclature, it is more likely to appear as a descriptive nickname, a dataset label, or a user handle in online resources rather than as a formal protein name. When documenting sequences, researchers typically use the sequence itself, the gene name, or the length notation (e.g., 167 aa).
