Antioxidant activity of biopigment fractions from golden apple snail eggs (Pomacea canaliculata)

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Biopigment is a natural non-toxic, renewable and environmental friendly dye. The golden apple snail eggs is known to contain carotenoid groups such as astaxanthin pigment. The purpose of this study was to determine the antioxidant activity of biopigment from acetone and methanol fractions with various in vitro test.

GOLDEN APPLE CHERRY SNAIL SHELL AS CATALYST FOR HETEROGENEOUS TRANSESTERIFICATION OF BIODIESEL [PDF]

Brazilian Journal of Chemical Engineering, 2018
ABSTRACT Calcium oxide catalysts prepared from golden apple cherry snail shell (Pomacea canaliculata) via two steps - deproteination and calcination - were compared: the structure was characterized by XRD and XRF and morphology by SEM. In addition, the effects of reaction time, catalyst loading amount, methanol:oil molar ratio and reaction temperature ...

The golden apple snail Pomacea canaliculata shifts primary production from benthic to pelagic habitats in simulated shallow lake systems

Knowledge and Management of Aquatic Ecosystems
Biological invasions are among the most serious threats to ecosystems. The golden apple snail Pomacea canaliculata (Lamarck, 1822) is considered one of the top 100 worst invasive alien species in the world. These snails consume benthic primary producers,

Teratogenic Effects of Serotonin Receptor 2B Disruption on the Migration and Cardiac Derivatives of the Cardiac Neural Crest

Birth Defects Research, Volume 117, Issue 7, July 2025.
ABSTRACT Background Cardiac neural crest cells (cNCCs) are critical for heart development, and their disruption can result in congenital heart defects. Serotonin (5‐HT) signaling, specifically via 5‐HT2B and 5‐HT2C receptors, regulates diverse physiological processes, including neural crest migration.
