a carboxyl group and an amino group

two amino groups

two carboxyl groups

two aromatic groups

an ester group and an amine group

Each is stabilized by inter-chain hydrogen bonds

All possible hydrogen bonds between the peptide carbonyl oxygen (C=O) and the amide hydrogen (N-H) are formed in each

The peptide bond in each is planar and trans

Each may occur in typical globular proteins

Each is an example of secondary structure

As blood calcium levels increase, parathyroid hormone (PTH) is reduced.

As more buffalo begin to run in a herd, the overall level of panic increases. This results in even more buffalo running.

A forest fire slowly expands outward, which provides it with even more fuel to burn.

During childbirth, oxytocin creates a stimulus which causes the hypothalamus to release more oxytocin.
