Document Summary

If there"s an o or n in a molecule, it"s polar: molecules made of only c"s and h"s are non-polar, covalent bond electron shared between each atom. Ionic bond electron given from one atom to another atom. Major compounds of the body: structures: aliphatic a compound in a straight chain, methyl groups (-ch3) determine if a gene is expressed or not (if there is a methyl group. Ene = double bond on a gene, it will not be expressed) Polar bears like water polar molecules are soluble in water. Ate = negatively charged, polar ion fatty acids long chains of c"s and h"s it"s non-polar free radicals shifts the balance so that we go into oxidative stress. Ie. a pore, gated channel, and carrier protein: active transport going against the flow of the concentration gradient, needs energy (atp) to do this. Ie. sodium potassium pump: secondary active transport doesn"t need atp applied to this process, but it uses the.
