A disaccharide (also called a double sugar or biose) is the sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage.
 Like monosaccharides, disaccharides are soluble in water.
 Three common examples are sucrose, lactose, and maltose.
The acorn nut is a type of fastener which gets its name from its shape.
 Acorn nut is its common name and it is also called a crown hex nut, blind nut, cap nut or domed cap nut.
 It is a nut that has a domed top to cover the threads.

 It is usually made of brass, steel, stainless steel (low carbon content) or nylon.
 It can also be chrome plated and given a mirror finish.
Electric catfish is the common name for the catfish (order Siluriformes) family Malapteruridae.
 This family includes two genera, "Malapterurus" and "Paradoxoglanis" with 19 species.
 Several species of this family have the ability to produce an electric shock of up to 350 volts using electroplaques of an electric organ.
 Electric catfish are found in tropical Africa and the Nile River.
 Electric catfish are usually nocturnal and carnivorous.
 Some species feed primarily on other fish, incapacitating their prey with electric discharges, but others are generalist bottom forager, feeding on things like invertebrates, fish eggs and detritus.
 The largest can grow to about 1.2 m long, but most species are far smaller.
DOCEX, the common name for Documents Expediting Project, was a program begun in 1946 by the Library of Congress (LoC) to distribute duplicate copies of government publications they received from federal government agencies.
 The program provided a means of obtaining documents that were not distributed through the Federal Depository Library Program, not for sale by the Government Printing Office, and not available directly from the publishing agency.
 Initially, DOCEX was begun by the Librarian of Congress to make formerly classified documents available after World War II.
 Libraries could subscribe to the service and make selections from lists sent by LoC.
 LoC had a special arrangement with the Central Intelligence Agency (CIA) to distribute CIA reference aids, which consist of things such as posters of communist leaders of various countries.
Xylomannan is a newly discovered antifreeze molecule, found in the freeze-tolerant Alaskan beetle "Upis ceramboides".
 Unlike antifreeze proteins, xylomannan is not a protein.
 Instead, it is a combination of a sugar (saccharide) and a fatty acid that is found in cell membranes.
 As such is expected to work in a different manner than AFPs.
 It is believed to work by incorporating itself directly into the cell membrane and preventing the freezing of water molecules within the cell.
A number of places and things have the name Blackfriars, derived from the Black Friars, a common name for the Dominican Order of friars or a Dominican friar.

Zhongzheng or Chungcheng () is a common name for places, roads, schools or organizations in Chinese-speaking areas, though today predominantly in Taiwan.
 The majority of these places and things are named after Chiang Chung-cheng, the preferred given name of Chiang Kai-shek.
 As a result, when translating into English or other non-Chinese languages, it sometimes would be replaced by "Chiang Kai-shek" instead of simply by transliteration.
Hyperetes (Greek: ὑπηρέτης ; pl.
 "hyperetai") was an Ancient Greek title.
 It is derived from ἐρέσσω "eresso", and therefore originally signifies a rower, but in later times the word was, with the exception of the soldiers or marines, applied to the whole body of persons who performed any service in a vessel.
 In a still wider sense it was applied to any person who acted as the assistant of another, and performed manual labour for him, whether in sacred or profane things, whence the word is sometimes used as synonymous with slave.
 Hence also the name was sometimes given to those men by whom the hoplites were accompanied when they took the field, and who carried the luggage, the provisions, and the shield of the hoplites.
 The more common name for this servant of the hoplites was skeuophoros.
