Peptides (from Gr. ÏÎµÏÏÏÏ, digested, derived from ÏÎ­ÏÏÎµÎ¹Î½, to digest) are biologically occurring short chains of amino acid monomers linked by peptide (amide) bonds. The covalent chemical bonds are formed when the carboxyl group of one amino acid reacts with the amino group of another. The shortest peptides are dipeptides, consisting of 2 amino acids joined by a single peptide bond, followed by tripeptides, tetrapeptides, etc.
Wind turbines can convert the energy in the wind into mechanical power that can be used for a variety of activities like pumping water. Wind turbines can also use generators to convert wind energy into electricity.
Part of the Electronics glossary: A wind turbine is a power generating device that is driven by the kinetic energy of the wind. Wind turbines general fall into one of two categories: Horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs). HAWTs, the more common type, consist of propeller-like rotors fixed around a central hub and facing into the wind, like a windmill.
