Animal lectins are classified on the basis of structural and functional studies in two types: the C-type, characterized by their dependence on calcium ions and the S-type which are not calcium-dependent, but thiol-dependent. In this late one, a group has been extensively studied as the S-Lac type. They are extracted with saline buffers added with lactose in presence of thiol agents, and constitute a family of structurally related protein which contain a series of conserved amino acids. They specifically bind to complementary glicoconjugates, and their biosynthesis and localization are developmentally regulated. Their role could be related to several biological activities in different organs.

UI	MeSH Term	Description	Entries
D007695	Killifishes	Small oviparous fishes mostly in the family Cyprinodontidae but also some members of families Aplocheilidae, Fundulidae, Profundulidae, and Rivulidae. Some killifishes are used in mosquito control. Killifishes are vertebrate model organisms in various fields, e.g., environmental toxicology and neurobiology, because of their short lifespans, ease of maintenance and large number of eggs produced.

D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick

D004555	Electric Fish	Fishes which generate an electric discharge. The voltage of the discharge varies from weak to strong in various groups of fish. The ELECTRIC ORGAN and electroplax are of prime interest in this group. They occur in more than one family.	Mormyrid,Mormyridae,Elephantfish,Elephantfishes,Fish, Electric,Mormyrids
