Fig. 5 is shown in by qualification collection of illustrative plates:
1390,1241 and 1427 kind of protein is identified respectively from wild peach, two thick sticks and three troubles.Three groups of protein had have 857 kinds.The peculiar protein 26 of wild peach 2 kinds, 136 kinds, the peculiar albumen of two thick sticks, three trouble peculiar protein 25s 3 kinds.The difference of different formative year protein may be relevant with its distinctive growth characteristics.Pilose antler protein group shows unique feature, containing a large amount of various functional proteins, these protein comprise structure constitutive protein matter, metabolic enzyme, extracellular matrix albumen, signal protein, cell multiplication related protein and metabolic protein, copy, transcribe protein with numerous paths such as transposition regulating effect and function.
The peculiar some albumen of wild peach has the function of Urogastron.The maximum feature of Urogastron is the proliferation and differentiation that can promote cell, thus replaces old and feeble and dead cell with the cell of new life.Application in makeup and healthcare products: Urogastron can promote skin cell proliferation, differentiation, accelerates metabolism, improves new cell skin proportion, reduces the skin mean age, makes skin be in younger state all the time.
The peculiar some protein be closely connected with lipid acid, the metabolism of cholesterol homenergic of two thick sticks, and also have the protein be closely related with the anabolism of intracellular nucleic acid and the biological function that mediates thereof, and this period is the fast growing period of pilose antler, need a large amount of energy supplies.
The peculiar albumen of three troubles relates generally to the protein of cytoskeleton organization, apoptosis, cell cycle secret contact.And branch off latter stage three, the participation of the necessary a large amount of apoptosis factor that comes off of pilose antler.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
