However, in the case of grape juice, browning is caused by just two enzymes: tyrosinase (EC 1.14.18.1, IUBMB [6]), which is naturally present in grapes [4, 5], and laccase (EC 1.10.3.2, IUBMB [6]), which is present only when the grapes are infected by Botrytis cinerea [5, 7]
Research context: The gap between animal evidence and human application is a central theme in peptide science
Dynamic and timely administration of antioxidant glutathione prevents LOsG/ROS-induced -cell failure and prediabetes
Leaves the skin looking clearer, firmer, and more even
These provide evidence for general biological principles (GH/IGF-1 axis supporting musculoskeletal health, collagen building blocks beneficial) lending credibility to targeted peptide interventions though not direct proof
