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.
Most of the other planets in our solar system also have moons. The number of moons ranges from one for the Earth, to as many as 21 for Uranus. Two of our planets, Mercury and Venus, have no moons. Jupiter has 16 known moons, Saturn has 18, and Neptune has 8. Pluto has one moon, but this moon is so large in comparison that many astronomers consider the two objects to be a double planet rather than a planet and a moon. Moons also vary greatly in size.
