Thủy phân xúc tác papain

By using the graphic theory the constant of reserve hydrolytic protein reaction catalyzed by papain have been calculated as follow: For the activation reaction: VM = 2.08 × 10-6 M.sec-1 , k2 = 1.04 × 10-1 .sec-1 , Ks = 1,79 × 10-4 M, = 0.265, KA = 1.54 × 10-4 M. For the inhibition reaction: VM = 0.67 × 10-3 M.sec-1 , Ks = 0.55 × 10-5 M, k2 = 33.5 sec-1 , Ki = 1.85× 10-3 M.

Động học ức chế thủy phân protein dự trữ, xúc tác bởi papain từ quả đu đủ xanh. The hydrolysis of reserve protein catalyzed by papain has been inhibited by Flavonoid. The inhibition was found competitive. Calculated constants of hydrolytic reaction have been estimated as following: VM = 0.67× 10-3 M.sec-1 ; k2 = 33.5 sec-1 ; Ks = 0.55× 10-5 M; Ki= 1.85× 10-3.

Nowadays, it is well known, a number of enzymes derived from a variety of different plants and microorganisms has been reported to 3.000. Among these, many of them p lay an important role in many practical applications, especially, hydrolases, in the food-processing for producing functional food of high quality. Enzymes seem to have a promising future. There is a presentation of some enzymes have successful application in the food-processing. The productivity (A%) of spare protein hydrolysis, catalyzed by papain has been calculated: for Scenedesmus = 64.0; for Spirulina = 52.

Trong phạm vi luận văn này, chúng tôi sẽ tiến hành thu nhận enzyme papain cs trong nhựa đu đủ và ứng dụng tính chất thủy phân protein của enzyme papain để làm xúc tác cho phản ứng thủy phân protein trong bánh dầu đậu phộng đã được ép lấy dầu. Chúng tôi chọn enzyme papain vì đây là enyme có hoạt tính protease cao, hiện diện nhiều trong nhựa trái đu đủ, một loại cây được trồng rất phổ biến ở nước ta. ...
