Dipeptide-comprising composition for oral administration
View Patent ↗A composition for oral administration is provided, which includes at least one dipeptide represented by the formula: (wherein X represents alanyl, and Y represents valine, leucine or isoleucine), with an object of providing a composition for oral administration which is excellent in nutrition, pharmacological effect and gustation, or providing a composition for oral administration which is excellent in processing characteristics such as solubility and tableting property.
1. A method comprising the step of orally administering to a human a composition, said composition comprising a comestible carrier and at least one dipeptide, wherein all dipeptides in said composition are represented by the formula:
wherein X is alanyl, and Y is selected from the group consisting of valine, leucine and isoleucine.
2. The method according to claim 1 , wherein the composition is a nutritious food or a drug product.
3. The method according to claim 2 , wherein the composition is a beverage.
4. The method according to claim 2 , wherein the composition is a drug product comprising a pharmaceutically acceptable carrier.
5. The method according to claim 4 , wherein the composition is a tablet or a granule.
6. The method according to claim 1 , wherein the composition comprises three dipeptides wherein Y is each of valine, leucine and isoleucine, respectively.
7. The method according to claim 6 , wherein the composition further comprises at least one kind of amino acid selected from the group consisting of valine, leucine and isoleucine.
8. The method according to claim 1 , wherein the composition further comprises at least one amino acid selected from the group consisting of valine, leucine and isoleucine.
9. The method according to claim 6 , wherein the total content of leucine in the composition is 1 to 3 times the total content of valine or total content of isoleucine.
10. The method according to claim 7 , wherein the total content of leucine in the composition is 1 to 3 times the total content of valine or total content of isoleucine.
11. The method according to claim 8 , wherein the total content of leucine in the composition is 1 to 3 times the total content of valine or total content of isoleucine.
12. The method according to claim 1 , wherein Y is leucine, and the composition is a beverage.
13. The method according to claim 12 , wherein the composition further comprises isoleucine.
14. The method according to claim 1 , wherein the composition provides 0.1 to 20 g/day of the total amount of valine, leucine and isoleucine to said human.
15. The method according to claim 14 , wherein the composition provides 1 to 10 g/day of the total amount of valine, leucine and isoleucine to said human.
16. The method according to claim 15 , wherein the composition provides 2 to 7 g/day of the total amount of valine, leucine and isoleucine to said human.
17. The method according to claim 6 , wherein the composition provides 0.1 to 20 g/day of the total amount of valine, leucine and isoleucine to said human.
18. The method according to claim 17 wherein the composition provides 1 to 10 g/day of the total amount of valine, leucine and isoleucine to said human.
19. The method according to claim 18 , wherein the composition provides 2 to 7 g/day of the total amount of valine, leucine and isoleucine to said human.
