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.
Some microphones have batteries inside them to supply this power.. Batteries go flat; they leak and wreck your mike; they go down in the middle of a recording; and they cost money to replace. Hence phantom power. Letâs have a close look at the XLR connector on the back of this mixer. Iâve got my voltmeter here to check the pins out. Pin one of this connector is the ground, or earth connection. So Iâll connect the negative meter lead to pin one. The phantom power switch is off at the moment. Letâs see what appears on pin two: no volts. And pin three: no volts. No lets switch the phantom power on for this channel: Back to pin two: ah, forty-eight volts! And pin three: the same, forty-eight volts.
