Peptides are broken down into amino acids by enzymes called proteases or peptidases. These enzymes catalyze the hydrolysis of peptide bonds, the chemical bonds that link amino acids together in a peptide or protein chain. Proteases are highly specific and are involved in various physiological processes, including digestion, where pancreatic proteases like trypsin, chymotrypsin, and carboxypeptidase play a key role. In the digestive system, the hydrolysis starts in the stomach with pepsin and continues in the small intestine with pancreatic enzymes, ensuring the peptides are broken down into amino acids, which can then be absorbed by the body.

Black snail repair emulsion is a skincare product designed to moisturize, repair, and improve skin elasticity, leveraging the regenerative properties of snail mucin. To use, first cleanse your face thoroughly. Follow up with your usual toner to prepare your skin. Then, take a moderate amount of the emulsion and apply it evenly across your face and neck, gently patting the product in to enhance absorption. It's best used twice daily, in the morning and at night, as part of your skincare routine. Due to its repairing properties, it's particularly beneficial for those with dry, sensitive, or acne-prone skin. However, always patch test a new product before full application to ensure compatibility with your skin.

Sodium azo dyes turn orange due to the azo group (-N=N-) in their molecular structure, which absorbs light predominantly in the visible spectrum. The specific absorption depends on the conjugation with other groups in the molecule. When light is absorbed, the remaining unabsorbed light reflects the color we see, in this case, orange. The azo group's ability to conjugate with aromatic rings results in the extensive delocalization of electrons. This electron delocalization lowers the energy required for electronic transitions, thereby shifting the absorption towards the longer wavelengths (visible range) and producing vibrant colors, including various shades of orange depending on the dye's exact chemical makeup.
