some regions of a polypeptide may coil or fold back on themselves. this is called <u>secondary structure</u> , and the coils or folds are held in place by <u>hydrogen bonds</u>
<u></u>
After translation, primary structure is just the arrangement of amino acids. The interactions between the carbonyl, amino, and side groups of the amino acid polymer backbone inside the chain result in the secondary structure of proteins. These interactions are primarily fueled by hydrogen bonds, which result in the formation of alpha helices and beta sheets, which are the primary features of proteins' secondary structures.
To create a useful three-dimensional structure, tertiary structure requires more interactions within the protein chain. Disulfide bonds between cysteines, hydrophobic contacts, ionic bonding, and dipole-dipole interactions are a few of these interactions. To create a useful, three-dimensional protein structure, several protein chains interact in quaternary structure.

Answer:
The name of the products are CO2 = carbon dioxide and H2O = water. The type of reaction is a combustion reaction.
Explanation:
The answer is hydroxides.
The elements of the group IA are termed as alkali metals, because their hydroxides are alkaline.
The equilibrium expression shows the ratio between
products and reactants. This expression is equal to the concentration of the
products raised to its coefficient divided by the concentration of the
reactants raised to its coefficient. The correct equilibrium expression for the
given reaction is:<span>
<span>H2CO3(aq) + H2O(l) = H3O+(aq) + HCO3-1(aq)
Kc = [HCO3-1] [H3O+] / [H2O] [H2CO3]</span></span>
