Jess (falconry) course of the spring/summer moult, when they are generally re-oiled and serviced as necessary. Jess (falconry) A jess (plural "jesses") is a thin strap, traditionally made from leather, used to tether a hawk or falcon in falconry. Jesses allow a falconer to keep control of a bird while it is on the glove or in training, and allow a bird to be secured on a perch outside its aviary. Jesses come in various types: Jesses are generally made from strips of leather as thin as possible, for which purpose kangaroo leather has become increasingly popular over the years, as it
Tether (cell biology) is used for carrying hydroxyethyl from hydroxyethyl TPP. This compound forms Acetyl- CoA, a convergent molecule in metabolic pathways. Another tether is biotin- lysine residue complex associated with pyruvate carboxylase, an enzyme which plays an important role in gluconeogenesis. It is involved in the production of oxaloacetate from pyruvate. One of the biological tethers used in the synthesis of fats is a β- mercaptoethylamine-pantothenate complex associated with an acyl carrier protein. Tether (cell biology) Biological cells which form bonds with a substrate and are at the same time subject to a flow can form long thin membrane cylinders called tethers,
