Deciphering the mechanism underlying poor aqueous solubility of extracted quinoa proteins.
Int J Biol Macromol
December 2024
Article Synopsis
- The study investigates why quinoa proteins have poor solubility by exploring their forms in water and how they interact with each other.
- Researchers analyzed the solubility of quinoa proteins in various concentrations and assessed changes in their stability over three weeks through methods like centrifugation and ultrafiltration.
- Findings revealed that proteins mainly exist as aggregates, leading to low solubility and significant precipitation during storage, but with time, they became kinetically stable due to stronger electrostatic forces and reduced hydrophobicity.
Article Synopsis
- Insomnia is a common problem in people with mental health issues, but doctors are still figuring out exactly how it differs in various conditions.
- Researchers studied 150 patients with different types of insomnia linked to mental health disorders like depression and anxiety to find out more about their sleep patterns.
- The results showed that those with bipolar mania had different sleep characteristics compared to those with depression and anxiety, and there were no big differences in their metabolic health indicators.
Intermolecular forces regulate in-vitro digestion of whey protein emulsion gels: Towards controlled lipid release.
J Colloid Interface Sci
November 2023
Hypothesis: The utilization of emulsion-filled protein hydrogels for controlled lipid release in the gastrointestinal tract (GIT) displays great potential in drug delivery and obesity treatment. However, how intermolecular interactions among protein molecules influence lipid digestion of the gels is still understudied.
Experiments: Differently structured whey protein emulsion gels were fabricated by heating emulsions with blocking of disulfide bonds (the "noncovalent" gel), noncovalent interactions (the "disulfide" gel), or neither of these (the "control" gel).
Background: Thyroid dysfunction is common in patients with major depressive disorder (MDD). However, few studies have examined risk factors for thyroid dysfunction in overweight or obese first-episode and drug-naïve (FEDN) MDD patients. This study aimed to investigate the prevalence and risk factors of thyroid dysfunction in FEDN MDD patients with comorbid high body mass index (BMI).

WPMs were prepared by grinding the heat-set whey protein gel containing 10 mM CaCl into small particles (10-20 µm). Then, 3 × 4 low-fat model mayonnaises were prepared by varying FG (0.

Rapid responses to sugar signaling and metabolism are essential for optimal growth and fitness, but the regulatory mechanisms underlying these are largely unknown. In this study, we found that the rapid induction of sugar responses in Arabidopsis () requires the W-box cis-elements in the promoter region of , a well-studied sugar response marker gene.
