It is the basis for building proteins in our body. Lysine is the first limiting amino acid needed to digest food proteins: in the lack of it, no matter how much proteins were in the food, these still not assimilated. To construct the proteins, the body uses only L-lysine.owever, a vegetarian diet and a low-fat diet, the need for lysine can be not fully satisfied. Lysine is found in abundance in red meat, chicken, turkey, dairy products such as yogurt and cottage cheese.
Large planets in the Solar System like Jupiter and Saturn are known to have large moons with some of the conditions for life. Therefore some scientists speculate that large extrasolar planets (and double planets) may have similarly large moons that are potentially habitable.
Other moons are asteroids captured into orbit by a larger body's gravity. Only the dwarf planet Pluto's moon Charon is thought to have formed from a collision like the one that gave rise to Earth's moon. No matter how they form, the moons are many. Only Mercury and Venus are moonless. Earth has one, Mars two. Neptune has 13 and Uranus 27. The gas giant Jupiter has 63 known moons. Saturn has at least 60âand 42 of those have been discovered since 1997.
