Isolation and identification of three ecdysteroid conjugates with a C-20 hydroxy group in eggs of Locusta migratoria

Tsoupras, Georges, Luu, Bang, Hoffmann, Jules A.·1982·Steroids

Abstract

Three ecdysteroids conjugates with a hydroxy group at C-20 were isolated from developing eggs of locusta migratoria and identified as 22-phosphate conjugates of 2-deoxy-20-hydroxy-ecdysone, 20-hydroxyecdysone and 20-hydroxyecdysone acetate.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Insects can synthesize 22-phosphate conjugates of 2-deoxy-20-HE, 20-HE acetate, and 20-HE; in female locusts and related species, all these conjugates are hydrolyzed during embryonic development, synthesizing biologically active hormones.

    “It has been reported that insects can synthesize 22-phosphate conjugates of 2-deoxy-20-HE, 20-HE acetate, and 20-HE; meanwhile, in female locusts and related species, all these conjugates are hydrolyzed during embryonic development, synthesizing biologically active hormones [208,209].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
