    • Introduction:
      Copper peptide powder is a compound that combines copper ions with small protein fragments called peptides. It is commonly used in skincareformulations due to its potential benefits for skin health and appearance.
    • Function:
      1. Improve dynamic wrinkles, relaxing muscles
                                                                    2. Anti-carbonylation, Antioxidation, Anti-saccharification, mainly used in cosmeti
    •   3. Promote rapid wound healing
      4. Widely used as cosmetic additive
    • The importance of peptides:
    • Many active substances in the human body are in the form of peptides. Peptides are involved in various fields of human hormones, nerves, cell growth and reproduction, and their importance is to regulate the physiological functions of various systems and cells in the body, activate the relevant enzyme systems in the body, promote the permeability of intermediate metabolic membranes, or control DNA transcription or affect specific protein synthesis, and ultimately produce specific physiological effects. Peptides are important substances involved in various cell functions in human body. Peptides can be synthesized into cells and regulate their functional activities. Peptides act as neurotransmitters in the body, transmitting information.

• II. Core Research Mechanism
  NAD⁺ is a core coenzyme essential for hundreds of dehydrogenase enzymes within cells, and it participates in all the basic biochemical metabolic cycles of cells. It exists in two forms: oxidized NAD⁺ and reduced NADH.
  Participates in mitochondrial aerobic respiration, catalyzes the synthesis of energy in ATP, and maintains the basic energy supply of the cell;
  2. Activate the Sirtuins family of longevity proteins, which are involved in DNA damage repair and regulation of cellular homeostasis;
  3. Regulate the sugar and lipid metabolism pathways, balance insulin signaling, and inhibit oxidative stress free radicals;
  4. Regulate the aging process of cells. As an organism ages, the internal content of endogenous NAD⁺ continuously decreases.
  III. Research Application Directions of the Laboratory (Prohibition of Promoting Oral/Medical Effects on Humans)
  1. Research on cellular energy metabolism
  Cell culture, mitochondrial function, in vitro experiments on aerobic/anaerobic respiration, suitable for basic metabolic research topics in biological laboratories.
