-ulosevariant of -ulous in scientific terms, as in granulose, ramulose.
[Latin -ulōsus. See -ule, -ose1]
▪ I.-ulose, suffix1A compound adjectival suffix representing L. -ulōsus, formed by the addition of -ōsus(see -ose) to stems in -ul-us, -a, -um, as angulōsus from angulus, fābulōsus from fābula, perīculōsus from perīculum. Such formations are rare in earlier Latin, but a considerable number are employed by post-Augustan writers, as Pliny, Columella, etc. Among the English examples which have their source in classical or post-classical forms are angulose, calculose, fabulose, fistulose, glandulose, nebulose, pustulose, ramulose, sabulose, vermiculose. On the analogy of these, various others have been introduced, as flosculose, globulose, granulose, scrofulose, siliculose, tubulose, tumulose. These forms are parallel to a certain number of those in -ulous, being as a rule either obsolete variants of these, or introduced later in order to convey the distinction commonly observed between the endings -ose and -ous.▪ II.-ulose, suffix2Biochem.|-jʊləʊz|[f. lævulose.]Used (in place of -ose2) to form the systematic names of ketoses from the names of the corresponding aldoses, esp. ketoses having the carbonyl group at the second carbon atom; as hexulose, ribulose, sedoheptulose.
ORIGIN: Repr. Latin-ulosus, formed by adding -osus (see -ose1) to nouns in -ulus, -ula, -ulum.
Forming adjectives with the sense ‘full of, having’, either directly from Latin words in -ulosus, as fistulose, glandulose, nebulose, etc., or as later formations on (words from) Latin stems, as granulose, nodulose, rugolose, etc. Many of these have corresp. forms in -ulous and are usu. either obsolete variants of these, or introduced later in order to convey the common distinction between words in -ose and -ous. 2 -ulose/jʊləʊz; in a few words-s/suffix2.
ORIGIN: from laev)ulose. Cf. -ose2.
Biochemistry. Forming the systematic names of ketoses from the names of the corresponding aldoses, esp. ketoses having the carbonyl group at the second carbon atom, as ribulose, sedoheptulose, xylulose.
