some regions of a polypeptide may coil or fold back on themselves. this is called secondary structure , and the coils or folds are held in place by hydrogen bonds

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.

Using Dimensional Analysis

<h3>Explanation:</h3>

Step 1: Define

3.75 × 10²⁵ atoms Ca

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

Set up: $\displaystyle 3.75 \cdot 10^{25} \ atoms \ Ca(\frac{1 \ mol \ Ca}{6.022 \cdot 10^{23} \ atoms \ Ca})$
Multiply/Divide: $\displaystyle 62.2717 \ mol \ Ca$

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

62.2717 mol Ca ≈ 62.3 mol Ca
