Description
L-Carnosine is a naturally occurring dipeptide composed of β-alanine and L-histidine, highly concentrated in mammalian muscle, brain, and eye lens tissues. It functions as a potent antioxidant and anti-glycation agent, scavenging reactive oxygen species (ROS) and transition metal ions to protect cells from oxidative stress. It inhibits non-enzymatic protein glycation and cross-linking induced by toxic aldehydes (e.g., acetaldehyde, malondialdehyde), delaying cellular senescence and supporting healthy aging. Additionally, it acts as a neurotransmitter and pH buffer in the brain, maintaining cellular homeostasis.
Key Applications
: Anti-aging formulations, neuroprotective agents, and cardiovascular health supplements.
Cosmetics: Anti-wrinkle, brightening, and antioxidant skincare products; reduces glycation-related skin aging.
Food & Beverages: Nutritional supplements, sports nutrition, and functional foods for muscle recovery and endurance.
Research: Biochemical studies on oxidative stress, glycation, and neurodegenerative diseases.
