Document Summary

There may be covalent bonds between r groups. Not all proteins have a quaternary structure. Protein junctions: channels, transporters, chemical messengers, enzymes, movement, structural, receptors. Nucleic acids: dna and rna, tells what amino acids to put into the protein, mrna carries primary structure sequence to cytoplasm, proteins must be the right shape, if you disrupt h bonds; shape changes. High temperature-denatures- shape changes- primary structure does not change only tertiary. Degrade-change in primary structure or order of amino acids: chemical reactions make and break covalent bonds. Degradation is a chemical reaction that may be enzyme controlled. Ph changes interactions between r groups thereby affecting structure. Temp, ion, and ph are homeostatically controlled. If i wanted to stop sodium movement across the membrane, i could degrade its protein. Dna: exons and introns, exons- what we need/is expressed, introns- the stuff between the exons. May be used in regulation: primary rna has both, splicing removes introns to create mrna.
