Caprine Respirovirus 3
Caprine may refer to: *A goat-antelope *Caprine, norleucine, aminoacid *Ovicaprids, goats and sheep taken together in archaeology and paleontology *Caprine, an adjective that means "pertaining to or belonging to the subfamily Caprinae" (see goat-antelope, caprine arthritis encephalitis virus ''Caprine arthritis encephalitis virus'' (''CAEV'') is a retrovirus which infects goats and cross-reacts immunologically with HIV, due to being from the same family of viruses. CAEV cannot be transmitted to humans, including through the consumpti ...

Goat-antelope
The subfamily Caprinae, also sometimes referred to as the tribe Caprini, is part of the ruminant family (biology), family Bovidae, and consists of mostly medium-sized bovids. A member of this subfamily is called a caprine, or, more informally, a goat-antelope (although they are not considered antelopes). Within this tribe, a prominent clade includes sheep and goats. Some earlier Taxonomy (biology), taxonomies considered Caprinae a separate family called Capridae (with the members being caprids), but now it is usually considered either a subfamily within the Bovidae, or a tribe within the subfamily Antilopinae of the family Bovidae, with caprines being a type of bovid. Characteristics Although most goat-antelopes are gregarious and have fairly stocky builds, they diverge in many other ways – the muskox (''Ovibos moschatus'') is adapted to the extreme cold of the tundra; the mountain goat (''Oreamnos americanus'') of North America is specialised for very rugged terrain; t ...

Norleucine
Norleucine (abbreviated as Nle) is an amino acid with the formula CH3(CH2)3CH(NH2)CO2H. A systematic name for this compound is 2-aminohexanoic acid. The compound is an isomer of the more common amino acid leucine. Like most other α-amino acids, norleucine is chiral. It is a white, water-soluble solid. Occurrence Together with norvaline, norleucine is found in small amounts in some bacterial strains where its concentration can approach millimolar. Its biosynthesis has been examined. It arises via the action of 2-isopropylmalate synthase on α-ketobutyrate. The incorporation of Nle into peptides reflects the imperfect selectivity of the associated aminoacyl-tRNA synthetase. In Miller–Urey experiments probing prebiotic synthesis of amino acids, norleucine and especially norvaline are formed. Uses It is nearly isosteric with methionine, even though it does not contain sulfur. For this reason, norleucine has been used to probe the role of methionine in Amyloid-β peptide (AβP ...

Ovicaprid
In zooarchaeology and paleontology, ovicaprids or caprines are domestic sheep and goat The goat or domestic goat (''Capra hircus'') is a domesticated species of goat-antelope typically kept as livestock. It was domesticated from the wild goat (''C. aegagrus'') of Southwest Asia and Eastern Europe. The goat is a member of the a ...s taken together. Distinguishing sheep and goats from post-cranial skeletal remains has historically been difficult, so in many archaeological reports, the two are often reported in a single ovis/capra category. This is problematic because of their different roles in early animal husbandry.Michael Buckley, "Zooarchaeology by Mass Spectrometry (ZooMS) Collagen Fingerprinting for the Species Identification of Archaeological Bone Fragments", p. 227-250 in Christina M. Giovas, Michelle J. LeFebvre, eds., ''Zooarchaeology in Practice'', Nonetheless, experienced analysts using systematic criteria can distinguish the two with high reliability. They can ...
