Marie Phisalix
Marie Félicie Phisalix (née Picot) (20 November 1861 — 18 January 1946) was a French scientist who researched snake venom and antidotes. She was awarded the Chevalier de la Legion d'honneur in 1923. Early life and education Phisalix was part of the Jurassic separatism movement. She was born in Besançon, the daughter of Camille Joséph Picot and Marie Josephine Dalloz. From 1882, she studied at the École normale supérieure de jeunes filles, which had recently been established. She qualified in 1889, where she taught herself and worked toward a medical degree. She was one of the first French women to become a doctor of medicine. She defended her thesis ''Histological, embryological and physiological research on the venom glands of the terrestrial salamander'' in 1900. Phisalix began to work on snake venom antidotes, and won a prize for her doctoral research on reptile and amphibian venoms. She identified that venom function is not adapted to attack or defence.

Snake Venom
Snake venom is a highly toxic saliva containing zootoxins that facilitates in the immobilization and digestion of prey. This also provides defense against threats. Snake venom is injected by unique fangs during a bite, whereas some species are also able to spit venom. The glands that secrete zootoxins are a modification of the parotid salivary glands found in other vertebrates and are usually located on each side of the head, below and behind the eye, and enclosed in a muscular sheath. The venom is stored in large glands called alveoli in which it's stored before being conveyed by a duct to the base of channeled or tubular fangs through which it's ejected. Venom contains more than 20 different compounds, which are mostly proteins and polypeptides. The complex mixture of proteins, enzymes, and various other substances has toxic and lethal properties. Venom serves to immobilize prey. Enzymes in venom play an important role in the digestion of prey, and various other substances ar ...
