Phytosterols, unsaturated fatty acid composition and accumulation in the almond kernel during harvesting period: Importance for development regulation
Bibliographic record
Abstract
The evolution of the composition of sterols and squalene during the maturation of the fruit of three cultivars (Achaak, Perlees and Mazetto) almond (Prunus amygdalus Batsh) was investigated. At the same time the evolution of oleic, linoleic and linolenic fatty acids was also studied. The qualitative and quantitative analyses were made by GC-MS and GC-FID. The present study is based on three axes: The first one is the structural and molecular identification of compounds sterolic and squalene, which are based on the principal of cleavage and the fragmentation characteristic of each peak provided by mass spectrometry. The second axis is interested in the physiological phenomenon of phytosterols accumulation: biosynthesis, evolution, and their relation with squalene as well as their interconversion. The third axis is an emergence of a relationship, which seems to exist, between the biosynthetic compounds of the glyceridic fraction of almond oil (mainly fatty acids) and those of the unsaponifiable fraction (particularly sterols). This relation may be established by 24-methylene cholesterol.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
