{"name":"C Suite Peptide Calculator","description":"Browser-based peptide sequence calculator accepting one-letter and separated three-letter amino-acid codes for theoretical elemental formula, monoisotopic mass, average molecular weight, protonated and deprotonated precursor m/z, supported terminal caps, estimated isoelectric point, net charge, sequence-derived extinction coefficient, Kyte-Doolittle GRAVY, amino-acid composition, amount of substance, mass concentration, and molarity. It publishes the parameter tables, references, assumptions, and interpretation limits used by each calculation.","homepage":"https://csuitebiologics.com/research-peptides/peptide-molecular-weight-calculator","version":["2026.09.21.1"],"function":[{"operation":[{"uri":"http://edamontology.org/operation_0250","term":"Protein property calculation"},{"uri":"http://edamontology.org/operation_0398","term":"Protein molecular weight calculation"},{"uri":"http://edamontology.org/operation_0403","term":"Protein isoelectric point calculation"},{"uri":"http://edamontology.org/operation_0236","term":"Sequence composition calculation"}],"input":[{"data":{"uri":"http://edamontology.org/data_2044","term":"Sequence"},"format":[{"uri":"http://edamontology.org/format_1929","term":"FASTA"}]}],"output":[{"data":{"uri":"http://edamontology.org/data_2955","term":"Sequence report"},"format":[{"uri":"http://edamontology.org/format_2331","term":"HTML"}]}],"note":"Calculates theoretical properties for a linear peptide sequence with free or explicitly selected N-acetyl and C-amide termini.
