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.
Extraterrestrial life is life that does not originate from Earth. It is also called alien life, or, if it is a sentient and/or relatively complex individual, an extraterrestrial or alien (or, to avoid confusion with the legal sense of alien , a  space alien ).he possibility of extraterrestrial life on the Moon was ruled out in the 1960s, and during the 1970s it became clear that most of the other bodies of the Solar System do not harbor highly developed life, although the question of primitive life on bodies in the Solar System remains an open question.
