The collagen can be extracted by using protease, which is known as Papain Soluble Collagen (PaSC). This study aimed to isolate the collagen from the snake-head fish skin using papain. The yield percentage and moisture content of PaSC in the skin was determined. Measurements using SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and Fourier transform infrared spectroscopy (FTIR) were performed to characterize the PaSC and its functional groups. The results showed that the yields and moisture content of PaSC were 8.9% and 6.07%, respectively. The PaSC characterized by two α-chains appeared as collagen type I. Fourier transform infrared (FTIR) spectra of PaSC confirmed a triple-helical structure of collagen. The results indicated that snake-head fish skin could be used as potential resources of collagen and papain can be used as an alternative affordable enzyme. ## Keywords - Papain - Fourier transform infrared spectroscopy - Chemistry - Fish - Polyacrylamide gel electrophoresis - Protease - Chromatography - Biochemistry - Biology - Enzyme - Fishery - Physics - Quantum mechanics --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
