Does the process of extraction of chondroitin sulfate change the molecular structure of the bovine source it is extracted from?

I have been prescribed Chondoritin Sulfate for my joints. For religious reasons, I don't have bovine. Hence my question. Does the process of extraction of chondroitin sulfate change the molecular structure of the bovine source it is extracted from? If it changes, then it's not bovine anymore and hence okay for me to consume.


There is a [paper here](https://reader.elsevier.com/reader/sd/pii/S0021925818563614?token=1A448B3942F61D5EA57D3B73A6345D97A1A485D2CF5CA1C666BCC8018EBFF529A38AD26B95FD2BC1284EEAA80A88477D&originRegion=eu-west-1&originCreation=20220221034743) that explains the extraction process in detail.


It's too technical for me, but would be grateful if a chemist could [read it](https://reader.elsevier.com/reader/sd/pii/S0021925818563614?token=1A448B3942F61D5EA57D3B73A6345D97A1A485D2CF5CA1C666BCC8018EBFF529A38AD26B95FD2BC1284EEAA80A88477D&originRegion=eu-west-1&originCreation=20220221034743) and verify if the molecular structure of the source is changed.


Thanks so much!
