Determination of (2E)-10-hydroxydec-2-enoic acid in Croatian royal jelly by high-performance liquid chromatography [PDF]

, 2017
Although health-promoting properties of royal jelly are known for many years, the absence of quality standards and methods prescribed for their determination leads to royal jelly adulteration. Royal jelly is a source of unique unsaturated fatty acid, (2E)

Enhanced skin penetration of 10-hydroxy-2-decenoic acid via anionic polymer formulations and skin hydration modulation

Journal of Dermatologic Science and Cosmetic Technology
Background: The skin barrier function is primarily determined by the stratum corneum (SC), which restricts the penetration of active compounds. Royal jelly (RJ) contains 10-hydroxy-2-decenoic acid (10H2DA), an unsaturated fatty acid with potential ...

Changes in flavour and aroma compounds of ultra‐high‐temperature processed and aseptic‐filled milk caused by storage conditions (temperature and duration)

International Journal of Dairy Technology, Volume 78, Issue 1, February 2025.
The changes during a 4‐month storage period at 5 or 25°C were investigated for sensory characteristics, volatiles and odorants of LL milk. The increase in sensory score of “plastic odour” was a specific change associated with the 25°C stored milk, and (Z)‐6‐dodecen‐4‐olide with “coconut” odour was related to the change.

GLYCOSYLTRANSFERASES OF RAT BRAIN THAT MAKE CEREBROSIDES: SUBSTRATE SPECIFICITY, INHIBITORS, AND ABNORMAL PRODUCTS 1 [PDF]

, 1976
Brain homogenates from young rats were assayed for their ability to synthesize cerebrosides from radioactive UDP-galactose or UDP-glucose and ceramide. A comparison of galactose transfer with ceramides made from different 2-hydroxy acids showed that the ...

Effects of patent foramen ovale in migraine: a metabolomics‐based study

The Journal of Physiology, Volume 603, Issue 4, Page 809-835, 15 February 2025.
Abstract figure legend Aura, cystatin‐C and calcium are biomarkers of PFO in migraine. PFO closure relieves migraine by regulating 5‐HT metabolism and redox reactions, especially in the posterior head. cTTE, contrast‐transthoracic echocardiography; DESI‐MSI, desorption electrospray ionization mass imaging; H&E, haematoxylin and eosin; PFO, patent ...

Drones and Workers of Honeybee Apis mellifera L. Dried Powder: Chemical Composition, Antioxidant, and Anticancer Assessment

Food Science &Nutrition, Volume 12, Issue 12, Page 10357-10369, December 2024.
This study explores honeybees as a food source through a chemical analysis of pupa and adult stages of honeybee drones and worker bees (Apis mellifera L.). Drones exhibited higher protein and fat content, while worker bees had the highest carbohydrates.

Mechanistic exploration of royal jelly production in caged honey bees (Apis mellifera)

Scientific Reports
This study investigates the impact of bee pollen nutrition on the royal jelly production of honey bees (Apis mellifera). Results demonstrate that pollen diet significantly impacts hypopharyngeal gland (HPG) development and the expression of genes ...

Investigating Natural and Induced Biofilm Dispersion in Listeria monocytogenes [PDF]

, 2017
Dispersion is a natural part of a biofilm life cycle in many bacterial species. Dispersion occurs when bacteria revert from a stationary, sessile state to a free-swimming, planktonic state and are freed from a biofilm.

Dissecting the Molecular Mechanism of 10-HDA Biosynthesis: Role of Acyl-CoA Delta(11) Desaturase and Transcriptional Regulators in Honeybee Mandibular Glands

Insects
10-Hydroxy-2-decenoic acid (10-HDA), a major fatty acid (FA) component of royal jelly, is synthesized in the mandibular glands (MGs) of worker honeybees.

Expression of Genes for a Flavin Adenine Dinucleotide-Binding Oxidoreductase and a Methyltransferase from Mycobacterium chlorophenolicum Is Necessary for Biosynthesis of 10-Methyl Stearic Acid from Oleic Acid in Escherichia coli [PDF]

, 2017
In living organisms, modified fatty acids are crucial for the functions of the cellular membranes and storage lipids where the fatty acids are esterified. Some bacteria produce a typical methyl-branched fatty acid, i.e., 10-methyl stearic acid (19:0Me10).
