pectinicadj.

Brit.

/pɛkˈtɪnɪk/, U.S.

/pɛkˈtɪnɪk/

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: pectin n., -ic suffix.

Etymology: < pectin n. + -ic suffix, after German pektinig (in pektinige Säure pectinic acid, T. von Fellenberg 1918, in Biochem. Zeitschr. 85 124). Compare earlier pectosic adj.

Chemistry and Biochemistry.

pectinic acid n. any of a class of colloidal polymers of galacturonic acid containing a significant proportion of methyl ester groups, produced by partial hydrolysis of pectins. Cf. pectic acid n. at pectic adj. 1.

ΚΠ

1925 Ann. Bot. 39 817 Fellenberg suggests that these products intermediate between pectin and pectic acid should be called pectinic acids.

1951 Z. I. Kertesz Pectic Substances xiv. 335 Until a few years ago it was believed that protopectinase is distinct from the enzyme which hydrolyzes the 1,4 glycosidic linkages in pectinic acids.

1988 Phytochemistry 19 735 (heading) Gibberellin-controlled pectinic acid and protein secretion in growing cells.
