imino(-) Chem.|ɪˈmiːnəʊ|
Comb. form of imine; also used attrib. as quasi-adj. So imino-chloride, imino-compound; iminosulphonic acid; imino-acid, any organic acid that contains an imino-group; also (now rare), an imidic acid; imino-ester or -ether, any compound that contains {b1}C(NH)OR and is consequently an ester of an imidic acid; more correctly called an imido-ester; imino-group, the group {b2}NH as it occurs in imines (in quot. 1906 it denotes what is more correctly called an imido-group).

LXXXIV. i. 692 The formation and properties of some iminoacid anhydrides of the type of the hypothetical iminoformic anhydride, NH:CH·O·CH:O. 1937Imino-acid [see imino-ether below]. 1953Fruton & Simmonds Gen. Biochem. iii. 49 The hydrolysis of a protein leads to the formation of a variety of amino acids... The compounds having the general formula shown are termed α-amino acids, whereas proline and hydroxyproline are more correctly designated α-imino acids; for convenience, however, these two cyclic compounds are also called amino acids. 1961Jrnl. Clin. Invest. XL. i. 843/1 Since nearly all of the hydroxyproline of the body is found in collagen, it has been suggested..that the urinary excretion of the imino acid may be an important index of collagen metabolism. 1967New Scientist 24 Aug. 375/1 The precise proportion of the imino-acid hydroxyproline in the important protein collagen.

LXXVIII. i. 295 The authors think it probable that aliphatic substituted imino-chlorides of aromatic acids are readily decomposed into alkyl chlorides and aromatic nitriles or their polymerides. 1904Ibid.

Chem. xxi. 314 In the presence of anhydrous hydrogen chloride, nitriles add alcohols to form imino esters: CH3C{b3}N + HOC2H5→CH3C{b2}NH{bbc1}OC2H5 . 1951C. R. Noller Chem. Org. Compounds xiii. 242 The corresponding O-alkyl derivatives, RC{b1}OR{btc2}NH, are known and are called imido esters (less correctly imino esters or imido ethers).

1906Jrnl. Chem. Soc. LXXXIX. ii. 1837 The members of the former class contain the grouping CO{btr1}NH·CO·{bbr1}NH·CO·, whereas in no member of the latter class is this grouping present... Each of the imino-groups contained in the above-mentioned grouping, being connected with two carbonyl groups, will be possessed of acidic properties. 1966Nowakowski & Clarke tr. Kretovich's Princ. Plant Biochem. i. 16 Proline, strictly speaking, is not an amino acid, as it contains an imino group ({b2}NH).
