1953 J. S. Fruton & S. 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.

1961 Jrnl. Clin. Investig. 40 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.

1908 Jrnl. Chem. Soc. 94 i. 419 The imino-esters were prepared by a modification of Pinner's method... The velocity of reaction of the free imino-esters in aqueous solution have been determined and the results are tabulated.

1951 C. R. Noller Chem. Org. Compounds xiii. 242 The corresponding O-alkyl derivatives, R^NH_C—OR, are known and are called imido esters (less correctly imino esters or imido ethers).

1906 Jrnl. Chem. Soc. 89 ii. 1837 The members of the former class contain the grouping CO^NH·CO·_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.
