plasmaln.

Brit.

/ˈplazm(ə)l/, U.S.

/ˈplæzm(ə)l/

Origin: A borrowing from German. Etymon: German Plasmal.

Etymology: < German Plasmal (R. Feulgen & K. Voit 1924, in Pflügers Arch. f. ges. Physiol. 206 399) < Plasma plasm n. + -al -al suffix². In plasmal reaction n. at Compounds after German Plasmalreaktion (1924 in the source cited above).

Biochemistry.

Any aldehyde resulting from the hydrolysis of a plasmalogen.

1925 Chem. Abstr. 19 1156 Plasmal is an aldehyde, a solid at ordinary temp[eratures].

1953 A. G. E. Pearse Histochem. ix. 211 Exposure of tissues to formalin for more than 6 hours would hydrolyse plasmalogen to plasmal, but that further exposure would destroy all the liberated plasmal.

1966 McGraw-Hill Encycl. Sci. & Technol. 10 397/2 The Feulgen test for plasmalogens depends on the liberation of plasmal, principally palmitaldehyde and stearaldehyde, from these lipids by the action of mercuric chloride and acetic acid.

1992 Jrnl. Biol. Chem. 267 11009/2 These results suggested the presence of plasmal (aliphatic aldehyde) in compounds A and B.

Compounds

plasmal reaction n. a modification of the Feulgen reaction for detecting plasmalogens and aldehydes in tissue.

1925 Chem. Abstr. 19 1156 In accordance with its aldehyde nature, plasmal quickly takes a violet color when stained with H₂SO₃ fuchsin... This staining process is termed the plasmal reaction,..and the presence of plasmal, or its precursor plasmalogen, in frozen sections of tissues can be shown microscopically.

1949 Stain Technol. 24 19 The plasmal reaction is here modified so that it is made specific for acetal lipids alone.

1975 Jrnl. Chromatogr. 107 157 The alk-1-enyl glyceryl ethers were explicitly differentiated by the plasmal reaction.
