Evaluation of Functional Properties and the Lipase Inhibitory Activity of Proteins from
Article in Recent advances in food, nutrition & agriculture, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
AIMS/
backgroundObesity is characterized by excessive body fat and is a chronic and complex disease. The medications used to date for the treatment of obesity have exhibited various side effects. Thus, new substances must be sought from alternative sources as antiobesity drugs. Recently, there has been increased interest in the study of bioactive peptides generated from plant proteins for functional food development. Plant proteins have exhibited pancreatic lipase inhibitory activity and can be potentially studied as sources of anti-obesity drugs for long-term use. Amaranthus cruentus seeds are very nutritious, with high protein content and medicinal properties. Hence, this study focuses on pancreatic lipase inhibitory activity and functional properties of Amaranthus cruentus seed protein isolates. MATERIALS AND
methodsProteins were isolated using conventional and thermal isoelectric precipitation methods. The protein's ability to inhibit lipases was assessed using both synthetic and natural substrates. The functional properties, such as nitrogen solubility, foaming test, emulsification test, and water and oil holding abilities, were evaluated. The protein isolates were characterized by SDS-PAGE and DSC. Cell line studies were performed on 3T3-L1 cell lines to determine the cytotoxicity and anti-adipogenic activity of protein isolates. RESULTS AND DISCUSSION: Proteins 1, 2, 3, and 4 were found to have high protein yield and protein content. SDS-PAGE characterization showed protein bands at different molecular weights (kDa). Protein isolates demonstrated good fun ctional properties and antilipase activity as compared to flour. In the cell line experiments, protein 1 exhibited a dose-dependent reduction in the lipid content.
conclusionA. cruentus seed protein could pave the way for the development of nutraceutical formulation in the treatment of obesity.
