Bioactive glasses have been synthesized through methods such as conventional melting, quenching, the sol–gel process, flame synthesis, and microwave irradiation.The synthesis of bioglass has been reviewed by various groups, with sol-gel synthesis being one of the most frequently used methods for producing bioglass composites, particularly for tissue engineering applications.
Bioactive metallic glass is a subset of bioactive glass, wherein the bulk material is composed of a metal-glass substrate and is coated with bioactive glass in order to make the material bioactive. The reasoning behind the introduction of the metallic base is to create a less brittle, stronger material that will be permanently implanted within ...
[2] [3] [1] It begins with acetyl-CoA and involves the stepwise condensation of two-carbon units, typically derived from malonyl-CoA , to form increasingly longer carbon chains. In fatty acid synthesis, these chains are fully reduced after each elongation step, while in polyketide synthesis, the reduction steps may be partially or completely ...
Four general approaches have been used to achieve this objective: 1) use of the bioactive ceramic as a coating on a metal or ceramic substrate 2)strengthening of the ceramic, such as via crystallization of glass 3) use of fracture mechanics as a design approach and 4) reinforcing of the ceramic with a second phase.
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives.A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae.
A bioactive compound is a compound that has an effect on a living organism, tissue or cell, usually demonstrated by basic research in vitro or in vivo in the laboratory. While dietary nutrients are essential to life, bioactive compounds have not been proved to be essential – as the body can function without them – or because their actions are obscured by nutrients fulfilling the function.

A large number of different methods of measuring the concentrations of substrates and products exist and many enzymes can be assayed in several different ways. Biochemists usually study enzyme-catalysed reactions using four types of experiments: [3] Initial rate experiments. When an enzyme is mixed with a large excess of the substrate, the ...
