# What unit is the length of a protein measured in?

Sorry if this question is obvious - I'm not familiar with proteomics so I'm not sure of the standard units.

In this paper, it talks about using the length of a protein to calculate the NSAF value. However, it doesn't specify the units. Would it be peptides, amino acids or nucleic acids? Or something else?

• The paper clearly states protein length (number of amino acids). Dec 19 '20 at 1:16
