Some interesting facts about leucine:
- Lycine is an essential amino acid
Lycine is an essential amino acid. This means the body cannot make it at all, or not in sufficient amounts for good health and it needs to be eaten as part of the diet every day.
- Lycine functions as a building block of protein in the body
Lycine, just like all the other amino acids, is one of the building blocks of all proteins in the body, which not only include muscles, but also all the other proteins required for normal function of the body.
Lysine competes with arginine for absorption in the body. Animal proteins have a higher lysine content and will ensure more lysine (than arginine) is absorbed
- Lysine competes with arginine for absorption
Lysine competes with arginine for absorption in the body. Animal proteins have a higher lysine content and will ensure more lysine (than arginine) is absorbed. Foods with a higher lysine:arginine ratio (such as animal foods) are required to prevent cold sores because of the competition between these two amino acids for absorption and due to arginine's impact on propagating the herpes virus.
- Lysine levels decrease in food processing
Lysine is one amino acids that is very sensitive to food processing, especially dry heat, which deteriorate its levels in the foods. This means that the amount of lysine in foods such as legumes will be much less if they are dry roasted or toasted than if the legumes were cooked in a different manner.
