Peptides 

TL;DR: Specific characteristics of antioxidative bioactive peptides, enzymatic production, methods to evaluate antioxidant capacity, bioavailability, and safety concerns of peptides are reviewed.

TL;DR: Results show that leptin is transported intact from blood to brain by a saturable system and inhibited the influx of 125I-leptin in a dose-dependent manner whereas unlabeled tyrosine and insulin, which have saturable transport systems, were without effect.

TL;DR: Storage of tissue in the solution produced no adverse effects upon tissue morphology, nor was LHRH immunoreactivity diminished or accompanied by elevated non-specific staining, and ultrastructural analysis of cryoprotected tissue revealed excellent preservation of cellular morphology.

TL;DR: These findings, demonstrating that exogenous NPY is capable of overriding mechanisms of satiety and body weight control, suggest that disturbances in NPY function may play a role in some disorders of eating behavior and body Weight regulation.

TL;DR: The role of membrane lipid composition, specifically non-bilayer lipids, on peptide activity will also be discussed, and structure-activity studies of these peptides reveal two main requirements for antimicrobial activity, a cationic charge and an induced amphipathic conformation.
