PURPOSE:To provide a nutrition-promoting medicine containing oligopeptide as an active component and effective in lowering ammonia level in blood and urine. CONSTITUTION:A nutrition-promoting medicine capable of effectively lowering the ammonia level in blood and the amount of ammonia secreted in urine without causing malnutrition, etc., is produced by adding >=5wt% oligopeptide (preferably having an average molecular weight of 360-2,000 and average chain length of 2-10) produced by the enzymatic hydrolysis of protein or a protein-containing substance as a nitrogen source to a nutrition-promoting agent and properly adding a lipid (e.g. vegetable or animal oil or fat, etc.), saccharide (e.g. cellulose, starch, dextrin, etc.) and other compound (e.g. vitamins, minerals, etc.) which is essential or desirable to take from nutritional point of view. A partial hydrolyzate of protein containing low-molecular-weight peptide is subjected to plastein reaction and the resynthesized polypeptide can be used as the above oligopeptide. |
