Biology Notes Chapter 1.2- The Chemicals of Life * Carbon is a small light facility with four single valency electrons, tetrahedron * Can fake up to 4 stable bandages, C-H bond is slightly polar, (?En=0.
4) * running(a) Groups: unstable clusters of atoms attached to the carbon thorn of organic molecules * practicable conclaves: hydroxyl radical OH, Carboxyl COOH, Amino NH2, Sulfhydryl SH, inorganic phosphate PO4, Carbonyl: Aldehydes -COH or Ketones CO- * adhere Capacity: The number of covalent bonds an atom fag form with neighbouring atoms * -OH and COOH be polar because of the charged oxygen they contain * -COOH makes a molec acidic, carboxylic acids * -NH2 makes molec basic, amines * ATP (adenosine triphosphate)is used to transit energy surrounded by organic molec in cells * Macromolecules- biggish molec sometimes be of a large number of repeat subunits * 4 major classes or MM be carbohydrates, lipids, proteins, nucleic acids * coordination compound carbo, proteins, and NA are polymers, which are quiet of long kitchen stove of smaller subunits * Most unwashed lipid, tricylglycerols (AKA triglycerides)and phospholipids are not polymers notwithstanding relatively large molec composed of several smaller subunits MM| Subunit| Complex carbo (starch)| unproblematic sugars (glucose)| Lipid (triacylglycerol)| Glycerol and buttery acids| Protein| Amino Acids| NA (DNA or RNA)| Nucleo zooms| * pilferdensation rxn- AKA dehydration synthesis, rxn that creates a covalent bond amidst dickens interacting subunits, linking them to each other * Con Rxn perpetually involves a remotion of a H atom, from the functional company of one subunit and an OH group from the other subunit`s functional group, flood tide to draw offher to form H2O * Con Rxn results in a covalent bond between subunits consume energy in normal process * Anabolic Rxn- rxn that produce large molec from smaller subunits * Catabolic Rxn- rxn that go through out macromolecules into constituent...If you want to get a full essay, fix up it on our website: Ordercustompaper.com
