Proteins are a second type of intracellular organic molecule. These substances are made from chains of smaller molecules called amino acids, and they serve a variety of functions in the cell, both catalytic and structural. For example, proteins called enzymes convert cellular molecules (whether prote...

Aramid, short for "aromatic polyamide," is a class of synthetic, high-performance fibers. Meta-aramid fibers were first commercially applied in the early 1960s, with para-aramid fibers being developed in following decade. They are unique because their structures, characterized by polymer chains, ...
Like other polymers, spandex is made from repeating chains of monomers that are held together with an acid. Early in the spandex development process, it was recognized that this material is highly heat-resistant, which means that notoriously heat-sensitive fabrics like nylon and polyester are impro...
A polymer is made up of very large chains of molecules. The glue used in slime comprises long chains of polyvinyl acetate molecules (that’s why we recommend PVA glue). These chains slide past one another fairly easily, that keeps the glue flowing. Chemical bonds are formed when you mix ...
Meanwhile, carbon insetting is when businesses invest in carbon reduction schemes within their own supply chains. Examples include a clothing manufacturer planting trees outside its factory, a restaurant growing its own vegetables (to reduce the emissions of the supplier delivering th...
