DNA/RNA/Protein and General Mol. Weight Calculator 2.0.0

The Chemical/Biochemical Pocket Companion, developed by the editors of Current Protocols, serves as a valuable resource for researchers in the field. This tool allows users to input or paste various nucleic acid base sequences or protein/peptide amino acid sequences, either in one- or three-letter codes, through an intuitive menu interface. It is designed to calculate the molecular weight efficiently.

In addition to providing molecular weights for known sequences, the companion facilitates estimations for unknown nucleic acid or protein/peptide sequences based on their length and the average molecular weights of bases or amino acids, enhancing its utility in practical applications.

The inclusion of a curated list of 1200 commonly encountered organic and inorganic compounds streamlines the process of calculating molecular weights for these substances. Furthermore, an accessible list of chemical elements allows users to incorporate them into any standard chemical formula seamlessly.
