High quality High purity Acetyl Tetrapeptide-3

I. Introduction

Carnosine (chemical name: β-alanyl-L-histidine) is a dipeptide composed of β-alanine and L-histidine, widely present in human muscle and brain tissues. As a natural antioxidant, carnosine possesses functions such as scavenging free radicals, inhibiting glycation reactions, and protecting cell membranes, playing a crucial role in human health.

Characteristics:

• Strong antioxidant properties: Carnosine can neutralize reactive oxygen species (ROS), preventing lipid peroxidation and protein oxidative damage.
• Anti-glycation effects: By competing with sugars for binding, carnosine prevents protein glycation and reduces the formation of advanced glycation end products (AGEs).
• Promotion of cell regeneration: Carnosine extends the regeneration cycle of fibroblasts, enhancing collagen and elastin synthesis.
• Low toxicity: Carnosine is non-toxic and highly safe, suitable for long-term use.

II. Application Areas

1. Anti-aging:
   • Efficacy: Reduces wrinkles and fine lines, improves skin elasticity, and delays skin aging.
   • Application products: Anti-aging serums, creams, eye creams, etc.

III. Mechanism of Action

1. Antioxidant effects:
   Carnosine prevents oxidative damage to cell membranes and proteins by scavenging free radicals, delaying aging.

2. Anti-glycation effects:
   Carnosine competes with sugars for binding, preventing protein glycation and reducing AGEs, thus protecting collagen and elastin.

3. Promotion of cell regeneration:
   Carnosine extends the regeneration cycle of fibroblasts, promoting collagen and elastin synthesis, enhancing skin elasticity.

4. Regulation of immunity:
   Carnosine regulates cellular and humoral immunity, enhancing the body's immune function.
