Lactic acid and oxidant, iodide, nitric acid, egg white can not coexist, otherwise it is harmful to human body. It is naturally found in the germination of milk, jam of fruit, juice of tomato, beer, wine and many higher plants.
Lactofen
The drug is absorbed by the stem and leaves of the stem, and the cell membrane is destroyed and the weeds are dead.

Lanthanum oxide is a chemical substance with the molecular formula of La2O3. Slightly soluble in water, easily soluble in acid, easy to absorb carbon dioxide and water in exposed air, mainly used for manufacturing precision optical glass and optical fiber.
Lapatinib ditosylate
Lapatinib (INN), used in the form of lapatinib ditosylate, (USAN) (Tykerb/Tyverb, GSK) is an orally active drugfor breast cancer and other
Lead Acetate Trihydrate
Lead acetate trihydrate is colorless crystal, white particle or powder, which will deliquesce. Soluble in water, sweet. Lead acetate trihydrate is used to produce all kinds of lead salts, pigments, dyestuffs, lead plating, polyester catalysts, waterproof paints, desiccants, pesticides and medicines.
Lead Chromate
Yellow or orange powder. Relative density d156.12. Melting point 844 ℃. Soluble in strong inorganic acid and alkali solution, insoluble in water and oil. High colouring power, strong covering power, no pulverization in the atmosphere. In the sunlight, the color becomes dark after a long time of sun exposure, and it is easy to become black when encountering hydrogen sulfide gas. The color light varies with the ratio of raw materials and manufacturing conditions. The products are lemon chrome yellow, light chrome yellow, medium chrome yellow, dark chrome yellow and orange chrome yellow.
Lead Dioxide
Dark brown microcrystalline heavy powder. Soluble in dilute hydrochloric acid, slightly soluble in acetic acid, insoluble in water and alcohol. Mainly used in the manufacture of dyes, matches, fireworks and synthetic rubber. It can be used to make lead dioxide anode instead of platinum anode.
Lead(II) Carbonate Basic
The molecular formula of basic lead carbonate is 2pbco3 · Pb (OH) 2, commonly known as white lead or white lead powder. White heavy powder. Toxic! The density is 6.14, which belongs to hexagonal system. It will decompose after heating and decompose at 400 ℃. Insoluble in water and ethanol, soluble in acetic acid and nitric acid, slightly soluble in carbon dioxide aqueous solution. Soluble in acetic acid, nitric acid and caustic solution. It can form lead soap with high fatty acids. Good weather resistance. However, the contact with air containing a small amount of hydrogen sulfide will turn black gradually.
Lead Oxide
Lead tetraoxide is most often used as a pigment for primer paints for iron objects.Currently it is mostly used for manufacture of glass, especially lead glass (crystal glass). Red lead is used as a curing agent in some polychloroprene rubber compounds. It is used in place of magnesium oxide to provide better water resistance properties.
Lead Oxide
Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula PbO. PbO occurs in two polymorphs, one litharge having a tetragonal crystal structure and the other massicot having an orthorhombic crystal structure.

Lestaurtinib
CAS 111358-88-4 Letatinib is a semi synthetic, oral, biologically effective receptor tyrosine kinase inhibitor, which has been shown to have therapeutic effects in the treatment of diseases such as acute myeloid leukemia, chronic myeloid leukemia and acute lymphocytic leukemia. Letatinib, a multi-target indole carbazole derivative, has been widely used in clinical trials to inhibit FLT3 autophosphorylation in vitro. A number of late stage trials are under way to study the drug in adult and child leukaemia.
Leuprorelin
Leuprorelin, goserellin, triptoreline and nafrareline are currently commonly used drugs to remove ovaries in the treatment of premenopausal breast cancer and prostate cancer (GnRH-a drugs for short). GnRH-a drugs are similar to GnRH in structure, competing for GnRH receptor in pituitary. When GnRH receptor in pituitary is fully occupied and exhausted by GnRH-a, it will have a downward regulating effect on pituitary, that is, prolapse The decrease of gonadotropins secreted by the body leads to the obvious decrease of sex hormones secreted by the ovary, which is similar to the operation of ovariectomy, which is called drug ovariectomy. Leuprorelin, a GnRH analogue, is a peptide composed of nine amino acids. This product can effectively inhibit the function of pituitary gonadal system. Its resistance to proteolytic enzyme and affinity to GnRH receptor of pituitary are stronger than GnRH. The activity of promoting the release of luteinizing hormone (LH) is about 20 times of GnRH, and its inhibition to pituitary gonadal function is also stronger than GnRH. At the initial stage of treatment, FSH, LH, estrogen or androgen may rise for a short time. Subsequently, FSH, LH and the secretion of estrogen or androgen are inhibited due to the decreased responsiveness of pituitary gland, which has therapeutic effect on sex hormone dependent diseases (such as prostate cancer, endometriosis, etc.).
