Carbohydrates have the general molecular formula CH 2 O, and thus were once thought to represent hydrated carbon. However, the arrangement of atoms in carbohydrates has little to do with water molecules. Starch and cellulose are two common carbohydrates.Both are macromolecules with molecular weights in the hundreds of thousands. Both are polymers (hence  polysaccharides ); that is, each is built from repeating units, monomers, much as a chain is built from its links.The monomers of both starch and cellulose are the same: units of the sugar glucose.hey are: 1  glucose, blood sugar, the immediate source of energy for cellular respiration. 2  galactose, a sugar in milk (and yogurt), and. 3  fructose, a sugar found in honey.
In a typical electret condenser microphone, it is the JFET that requires unbalanced bias and the preamplifier that requires balanced phantom power. This means that a condenser microphone requiring phantom power will not work with an input that only supplies bias, e.g. a wireless transmitter.
How does phantom power work? The power can be provided by a battery located inside of the mic; an example is the Shure PG81 that operates from a single AA battery. Alternatively (and most commonly) the DC power is provided by the pre-amp/mixer and delivered to the condenser microphone via the mic cable. This method is referred to as phantom power. The worldwide standard for phantom power is 11 to 52 volts of DC (typical studio mics run on 48v). Your preamp will typically have a button labelled 48v, which allows you to turn this on/off. However, some older mixers and cheaper audio interfaces may not have phantom power. In this case, an external phantom power supply can be added between the condenser mic and the preamp.
