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.
A wind turbine is designed to produce power over a range of wind speeds. All wind turbines are designed for a maximum wind speed, called the survival speed, above which they will be damaged. The survival speed of commercial wind turbines is in the range of 40 m/s (144 km/h, 89 MPH) to 72 m/s (259 km/h, 161 MPH).
