Peptide Stability

The chemical stability of peptides is very dependent on amino acid composition and sequence. Lyophilized peptides are generally more stable than their counterparts in solution. The following are potential degradation pathways for peptides: 1. Hydrolysis - This is generally a problem in peptides containing Asp (D) in [...]

Growth hormone-releasing activity of hexarelin after intravenous, subcutaneous, intranasal, and oral administration

Abstract We evaluated the GH-releasing activity of hexarelin, a new synthetic hexapeptide, after i.v. (1 and 2 micrograms/kg), sc (1.5 and 3 micrograms/kg), intranasal (20 micrograms/kg), and oral (po; 20 and 40 mg) administration to 12 healthy young volunteers. Reference treatments were i.v. saline and [...]

Effect of Gelatin (hydroxyprolylglycine) Consumption

The dipeptide hydroxyprolylglycine, present in gelatine circulates in your blood after you eat either gelatine or collagen and this will probably have an anabolic effect. In addition, it will also stimulate the formation of muscle fibers – along with their mass and strength. Researchers working [...]
