Homework Answers
Two amino acid are joined to each other by the help of peptide
bond ,also known as amide linkage . Peptide bonds are amide
linkages which are formed between alpha amino group of one amino
acid and alpha carbonyl group of another . This reaction is called
dehydration process,as a water molecule is removed and the linked
amino acid known as amino acid residues . The petide bond has
partial double bond character .

Identify the structure of amino acids, and describe the process by which they join together to form polypeptides. Describe the 4 different groups of amino acids and their properties (Neutral, Polar, Acidic, Basic). Describe the levels of structure of proteins (primary, secondary, tertiary, and quaternary), including what bonds and interactions occur at EACH level. Describe denaturation of a protein and indicate how temperature and pH affect the protein functions. Describe the major functions of proteins

Polymerization of amino acids into a polypeptide requires energy. In terms of chemical thermodynamics, the chemical energy for peptide bond formation in translation technically comes from: hydrolysis of GTP hydrolysis of ATP translocation of the ribosome as it moves along the mRNA ribosomal RNA (rRNA) secondary structure transcription of the mRNA that is being translated Transfer RNA (tRNA) is a ribonucleic acid about 50-60 nucleotides long. When a tRNA gets "charged" by covalent addition of its cognate amino acid, to...

9. The bond linking together amino acids to form peptides is called a atom of atom of the amine group. bond. This involves a covalent bond linking the the carboxylate group of one amino acid to the 10. Peptides are classi fied according to the number of amino acids linked together. As such, peptides containing 2, 3, and 4 amino acids would be classified as a(n) , and respectively. A peptide containing five or more amino acid is a(n) 11....

Proteins are polymers of amino acids that can exist in ordered structures stabilized by a variety of molecular interactions. However, when certain conditions are changed, the compact structure of a polypeptide chain may collapse into a random coil. This structural change may be regarded as a phase transition occurring at a characteristic transition temperature, the melting temperature, Tm, which increases with the strength and number of intermolecular interactions in the chain. A thermodynamic treatment allows predictions to be made of...
