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.
It could be that our home galaxy, the Milky Way, is not an entirely hospitable galaxy for life, according to a scientific report last month that suggests other galaxies in the universe could host 10,000x more habitable planets than the Milky Way.
