A kind of nutritious oligo-peptide liquid, which contains rich nutrients and about 3 percent oligo -peptides whose average molecular weight is 538 Dalton, was prepared by means of the controlled enzymatic hydrolysis technology of snake meat and the correct refining technology on the crude product.
A kind of oligo-peptide nutrient solution,which is rich in nutrition and consists about 3 percent short oligo-peptides whose average molecular weight is 538,was prepared and from snake meat by means of the controlled enzymolysis technology and the correct refining technology.
Experimental results showed that the circumstances resemble oligopeptide. The ligand was found to form 1:1 complexes with metal ions. The order of their logarithmic values is as follows: Cu~(2+)>Zn~(2+)>Co~(2+),being in concordance with Irving-Williams order.
The snake meat product of which 22.3 percent was enzyme hydrolyzed contains all kinds of nutrient components (except protein) of the original snake meat. The limited enzyme-hydrolyzed product contains about 3 percent oligo-peptides whose average relative molecular weight is 538 Dalton. These oligo-peptides account for 56.28 percent of the total amino acids, the free amino acids account for only 43.72 percent.
logK ZnH-2 L=-12.12.The cumulative protonation constants under the same conditions were β H 1=2.24×10 2; β H 2=4.15×10 3.The circumstances resemble oligopeptide. The ligand was found to form 1∶1 neutral complexes with metal ions.
Our goals are to establish an in vitro screening system and to evaluate a new approach in improving oral absorption of peptides and peptide-like drugs by overexpression of the human intestinal oligo-peptide transporter (hPepTl).
TWO Soy protein hydrolysates with diffetent degree of hydrolysis (DH) were produced by enzymatic hydrolysis of soy protein isolate, and the iron-binding capacity of the peptides thus obtained was measured by adding the Fo (Ⅲ) to the hydrolysates and determining the excessive iron with potassium thiocyanate after binding. It was found that the iron-binding capacity of these two peptides with high DH had relation to neither the concentration nor the DH of the peptides.
Zhibibugudana──a special and new medicinal preparation for relieving pain and numbness caused by cold, damp etc. ,has been prepared by using a proved recipe of traditional Chinese medicine processed by bio-effectiveness method. Bio-effecivetness means that macro-molecular matter in medicinal herbs, such as cellulose, crude protein, starch and pectin having no medicinal effect in general preparation made by decocting, boiling and exracting, is biodegradated and converted to medium molecular-weight matter kee...
With the new technology of compoound enzyme, the protein in swine blood can be degraded into 18 types of amino acids and low peptide. This technology can increase the digestibility of swine blood from 20% to 90%, and the rate of protein hydrolysis can reach 99. 5 %. In production,the proportion of amino caid is 85. 5 % and 8 essential amino acids is 36. 1%. The index of microorganism and chemistry is accord with Nation Fed Hygiene demands. This advanced technology is no pollution, especially, the productio...
