Document Summary
2b: macromolecules macromolecule s1 large, organized molecules that are typically created by polymerization biological macromolecules (biomolecules) provide the structure and carry out the activities of a cell. Of the cell itself contractile proteins, flagella proteins proteins. Within the cell motor proteins defense antibodies, complement proteins amino acids are connected in linear polymers of a specific sequence. 20 genetically encoded amino acid monomers to pick from many can be created; 2020 variations string of amino acids (aas) = peptide (di-, tri-, tetra- ) or polypeptide. Polypeptide we ascribe function to = protein sometimes 2 or more peptide chains (subunits) combine to form mature, functional protein. Give each amino acid its unique properties a. a. are bonded by amide linkage, called peptide bond proteins are long polymers of a. a. linked by peptide bonds, always written with n- terminus toward left, c-terminus toward end.
