Briefly explain the 20 known amino acids. How do Hsp70-like proteins affect existing interactions between proteins? How do peptide bonds, polypeptides, and polypeptide chains relate to amino acids? How does an amino acid become attached to a tRNA molecule? What mechanism ensures amino acids get ...
How do peptide bonds, polypeptides, and polypeptide chains relate to amino acids? Amino Acids: Amino acids are small molecules that contain functional groups including an amino group and a carboxylic acid group (hence the name). These are used as monomers to build larger molecules...
Proteins are made of the monomer amino acids. The exact sequence of amino acids is known as the primary structure of a protein. The secondary structure has to do with whether the amino acid chain folds into beta pleated sheets...
The ssrA tag is a natural degron that is added to polypeptides during translation in response to the absence of a stop codon on the mRNA and other disturbances in translation (6). The tagging is done by a proteinquality-control system, conserved throughout bacteria, consisting of the ssrA ...
The 2nd and 4th terms are proportional the respective numbers of amino acids in the polypeptides of the partially unfolded MHC α1α2–α3 joint (\({n}_{{{\rm{p}}},{{{\rm{MHC}}}\)) and TCR Vα–Cα joint (\({n}_{{{\rm{p}}},{{{\rm{TCR}}}\)), which can be combin...
How do peptide bonds, polypeptides, and polypeptide chains relate to amino acids? Why is it necessary for polysaccharides, such as starch or cellulose, to be digested outside of the cell even though disaccharides, such as lactose or sucrose, are digestible inside the cell?
How do proteins facilitate metabolic pathways in the human body? Proteins: Proteins are complex biochemical molecules. Organisms consist largely of proteins, which serve numerous functions throughout the body. Proteins are made of a string of amino ...
How does the structure of fatty acids compare to the basic units found in other macromolecules? Describe one example. HINT: Think about the structure of fatty acids as compared to the long chains found in other macromolecules. How d...
How do quality control mechanisms act to prevent the synthesis of damaged proteins? How can you disrupt the different biological functions of proteins? (i) Met, Ser, Leu [{Blank}] (ii) Ile, Ser, Phe [{Blank}] For the above polypeptides, explain why changing (i) to (...
How do proteins transform from polypeptides to helix or pleated sheets? What is the function of tRNA in protein synthesis? What is the mutation that does not affect the function of the expressed protein called? Explain the structure of amino acids and primary, secon...
