/ˈproʊˌtinˌɔɪd/,

/ˈproʊtnˌɔɪd/

Origin: Formed within English, by derivation. Etymons: protein n., -oid suffix.

Etymology: < protein n. + -oid suffix.

Biochemistry.

A. adj.

Resembling a protein; spec. of, relating to, or of the nature of a proteinoid or proteinoids. rare before mid 20th cent.

ΚΠ

1909 Cent. Dict. Suppl. Proteinoid, having the character of a protein (albumin).

1940 Jrnl. Amer. Chem. Soc. 62 2677/1 The opening of a proteinoid S–S linkage with attachment of the carcinogen to one sulfur and of hydrogen to the other.

1977 A. Hallam Planet Earth 236 (caption) Cell-like structures called ‘proteinoid microspheres’ have been produced by evaporating organic chemicals on hot lava beds.

1990 J. Grant Great Unsolved Mysteries Sci. (BNC) 27 Various experiments done in volcanic environments have shown that proteinoid globules are very likely to form in such regions.

B. n.

A protein-like polypeptide or mixture of polypeptides obtained by heating a mixture of amino acids.

ΚΠ

1932 Jrnl. Physical Chem. 36 1807 Diketopiperazine groupings..are probably present in these proteinoids.

1956 S. W. Fox in Amer. Scientist 44 353 Evidence that proteinoids can be formed by heating one or two amino acids has now accumulated.

1968 New Scientist 4 Apr. 41/2 Perhaps the most striking similarity that proteinoids bear to true proteins..is that..they act like enzymes.

1991 Sci. Amer. Feb. 103/1 Fox argued then—and continues to do so—that these ‘proteinoids’ represent the first cells, but his work has fallen out of favor among many scientists.
