What Is “Plant Collagen”? Distinguishing Ingredient Types, Structural Differences, Production Methods, and Skincare Effects
“Plant collagen” in skincare products does not refer to a single substance with a completely uniform composition and structure. The term may refer to plant-derived protein peptides such as hydrolyzed soy protein and hydrolyzed wheat protein; it may also refer to recombinant collagen produced ...
Mechanisms by Which PDRN Participates in Skin Repair: A2A Receptor-Related Signaling, Nucleotide Salvage, and Extracellular Matrix Remodeling
Polydeoxyribonucleotide (PDRN) is a mixture of DNA fragments composed of deoxyribonucleotides linked through 3′,5′-phosphodiester bonds. PDRN is not a single compound with a fixed molecular weight. Different raw materials may vary considerably in average chain length, molecular weight ...
Regulatory Mechanisms of Depression-Related Neurotransmitter, Stress, and Synaptic Plasticity Targets
Depression involves multilevel abnormalities in monoaminergic transmission, the balance between glutamate and GABA, regulation of the stress axis, and synaptic plasticity. Different targets separately influence mood, reward, cognition, sleep, and stress responses and together form an ...
Mechanisms of Retinol Action in the Skin: From Metabolic Activation and RAR/RXR-Mediated Transcriptional Regulation to Epidermal Renewal and Collagen Homeostasis
In skincare products, retinol generally refers to all-trans-retinol. It has the molecular formula C₂₀H₃₀O and belongs to the naturally occurring vitamin A family of compounds.
Construction, Characterization, and Neurological Disease Modeling of Microglia-Containing Brain Organoids
Microglia-containing human brain organoids (MC-HBOs) integrate neural cells, glial cells, and resident immune cells of the central nervous system within a three-dimensional culture system and can be used to analyze the roles of microglia in brain development, neuroinflammation, and ...
Build the Three-Membered Ring First, or Form the Carbon–Nitrogen Bond First?—Retrosynthetic Strategies, Route Selection, and Stereochemical Control in Cyclopropylamine Synthesis
Cyclopropylamines combine a three-membered cyclopropane carbon ring and a nitrogen-containing functional group within the same molecule. Cyclopropane possesses high ring strain and distinctive carbon–carbon bond orbital characteristics, while the nitrogen atom can participate in protonation, ...
What Determines Collagen Function: From Triple-Helix Formation to Hierarchical Assembly, Crosslink Maturation, and Dynamic Remodeling
Collagen is often described as a “supporting component” of the skin, bone, cartilage, and tendons. Although this description reflects the structural role of collagen, it can easily lead to an oversimplified assumption: the higher the collagen content, the better the condition of the tissue.
Structure and Reactivity of Furan Compounds: How Substituents, Ring Fusion, and Degree of Hydrogenation Affect Reaction Sites and Application Directions
Furan, furfural, 5-hydroxymethylfurfural, 2,5-furandicarboxylic acid, furanboronic acids, benzofuran, and tetrahydrofuran all contain a five-membered oxygen-containing ring, yet they play different roles in chemical reactions. Furfural is commonly used as an intermediate for multiple ...
