Scaling Units & Relative Units

Scaling Units
mg/g FW = 10.0 * (% FW)
% FW = (mg/g FW) / 10.0
µg/g FW = 10.0 * (mg/100g FW)
mg/100g FW = (µg/g FW) / 10.0

Relative Units
TotalAA = The collection of analyte values with the same Data_Source, Study_ID, and Sample_ID and whose Analyte Category Code is AMINO_ACID.

TotalP = The value of the analyte PROTEIN.

TotalFA = The collection of analyte values with the same Data_Source, Study_ID, and Sample_ID and whose Analyte Category Code is FATTY_ACID.

åsum() = The summarization function

AA_i= Individual Amino Acid value
FA_i= Individual Fatty Acid value

Units for Amino Acids
% Total Amino Acids= ((mg/g FW AA_i) / åsum (mg/g FW TotalAA )) * 100
% Total Protein = ((mg/g FW AA_i) / ((% FW TotalP )*10)) * 100

Units for Fatty Acids
% Total Fatty Acids= (% FW FA_i/ åsum ( % FW TotalFA )) * 100
