Coo-, O=C-O- Four classes of biological macromolecules - Answer ️️ -Proteins, carbohydrates, nucleic acids, lipids SPONCH - Answer ️️ -Sulfur phosphorous oxygen nitrogen carbon hydrogen polymer - Answer ️️ -a long molecule consisting of many similar or identical monomers linked together by covalent bonds. R group - Answer ️️ -a functional group that defines a particular amino acid that makes it a specific protein (20 amino acids) aka side chain Catalyst - Answer ️️ -Speed up chemical reactions but remain unchanged by the reaction. monomers - Answer ️️ -repeating units that serve as the building blocks of a polymer enzymes - Answer ️️ -specialized macromolecules that speed up chemical reactions in cells alpha carbon - Answer ️️ -the central carbon atom of each amino acid Atomic number - Answer ️️ -number of protons atomic mass - Answer ️️ -number of protons plus number of neutrons dehydration synthesis - Answer ️️ -a chemical reaction in which two molecules become covalently bonded to each other with the removal of a water molecule. amino acid backbone - Answer ️️ -The structure comprised of the amino group, carboxyl group with a central alpha carbon atom. dehydration reaction - Answer ️️ -A chemical reaction in which two molecules covalently bond to each other with the removal of a water molecule. Ionic bond - Answer ️️ -formed when two oppositely charged ions attract Hydrophobic - Answer ️️ -non polar, afraid of water Disulfide bond - Answer ️️ -double (di) bond between two Sulfur (sulfide) atoms in cysteine side chains. They stabilize tertiary and quaternary structures of a protein. carbohydrates - Answer ️️ -Organic compounds composed of carbon, hydrogen, and oxygen in a ratio of one carbon atom to two hydrogen atoms to one oxygen atom. They exist as monosaccharides, disaccharides, and polysaccharides. protein - Answer ️️ -a macromolecule consisting of one or more polypeptides chains made up amino acids folded and coiled into a specific three-dimensional structure. polar - Answer ️️ -Amino acid Molecule with partial charges. Mixes with water. covalent bond - Answer ️️ -formed when the difference in electronegativity between A atoms is equal they then share electrons Polar covalent bond - Answer ️️ -when electrons are unequally shared between Atoms because they have different electronegativities Functions of proteins - Answer ️️ -structural support, catalyst, transport, defense, movement, regulatio
