Leather part for their skins. Kangaroo leather is used to make items that must be strong and flexible. It is the material most commonly used in bullwhips. Some motorcyclists favor kangaroo leather for motorcycle leathers because of its light weight and abrasion resistance. Kangaroo leather is also used for falconry jesses, soccer footwear, and boxing speed bags. Although originally raised for their feathers in the 19th century, ostriches are now more popular for both meat and leather. Ostrich leather has a characteristic "goose bump" look because of the large follicles where the feathers grew. Different processes produce different finishes for many
Tether (cell biology) 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, which connect the adherent area to the main body of the cell. Under physiological conditions, neutrophil tethers can extend to several micrometers. In biochemistry, a tether is a molecule that carries 1 or 2 carbon intermediates from one active site to another. They are commonly used in lipid synthesis, gluconeogenesis, conversion of pyruvate into Acetyl CoA via PDH complex. Common tethers are lipoate -lysine residue complex associated with dihydrolipoyl transacetylase, which
