Conformity

Conformity is the change in a person’s behavior to go along with the group, even if that person does not agree with the group. Asch’s Original Study Solomon Asch conducted several experiments in the 1950s to determine how people are affected by the thoughts and behaviors of other people. In one study, a group of participants was shown a series of printed line segments of different lengths: a, b, and c. Participants were then shown a fourth line segment: x. They were asked to identify which...

Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce the activation energies of biochemical reactions by forming complexes with its substrates. The lowering of activation energies favor an increase in the rates of biochemical reactions. Enzyme deficiencies can often translate into life-threatening diseases. For example, a genetic abnormality resulting in the deficiency of the enzyme G6PD...

A Minority of One: Conformity to Group Norms

Source: William Brady & Jay Van Bavel—New York University It is obvious that we are influenced by those around us, but in the early to mid 1900's, psychologists began to study how potent social influence can be on our thoughts and behaviors. Motivated in part by attempts to explain the behaviors of Nazi soldiers in World War II, one topic of considerable interest at the time in psychology was conformity, the phenomenon in which people match their attitudes, behaviors, or beliefs to group...

Spatial Separation of Molecular Conformers and Clusters

We present a technique that allows the spatial separation of different conformers or clusters present in a molecular beam. An electrostatic deflector is used to separate species by their mass-to-dipole moment ratio, leading to the production of gas-phase ensembles of a single conformer or cluster stoichiometry.

Conformations of Butane

Unlike ethane and propane that have only two major conformations, butane has more than two conformers. The staggered form of butane in which the bulky methyl groups on the two carbons are placed on opposite sides, that is, at a dihedral angle of 180°, is the lowest energy, most stable form — called the anti conformer. This conformation is stabilized due to the absence of steric repulsion between the largely spaced out methyl groups. The other two staggered conformations are degenerate and have...

Hydrogen bonds, ionic forces, hydrophobic effects, and disulfide bridges collectively stabilize the enzyme’s three-dimensional arrangement. Their combined influence preserves the spatial relationships needed for molecule recognition and catalysis, although the structure is not necessarily rigid. Changes that disrupt these interactions can alter the placement of important regions and reduce the enzyme’s ability to support its biochemical reaction.
Substrate binding can trigger an induced-fit conformational change that brings catalytic residues into a productive arrangement. Rather than merely occupying a preformed site, the substrate helps shift the enzyme into a reaction-ready state. This mechanism explains how structural movement contributes to catalysis and why changes affecting flexibility or residue positioning can influence reaction performance.
Allosteric regulation occurs when a molecule binds to a site separate from the active site and causes a conformational shift. That structural change can enhance or inhibit enzyme activity by influencing the active region indirectly. Because this mechanism connects remote binding events with catalytic function, it provides an important basis for controlling biochemical pathways and metabolic regulation.
A mutation can alter interactions that maintain the enzyme’s conformation, including hydrogen bonds, ionic forces, hydrophobic effects, or disulfide bridges. Even when the active site remains unchanged in sequence, its three-dimensional positioning may shift or become less stable. Studying these structural consequences helps explain how mutations produce enzyme-related dysfunction through altered recognition or catalysis.
Drug design can focus on structural features that control enzyme recognition, catalysis, or regulation. Compounds may be considered for how they interact with the active site or with separate sites capable of producing conformational changes. Understanding these relationships helps researchers seek molecules that inhibit or modify activity by influencing the enzyme’s functional structure.
Conformational changes show how binding events can alter enzyme activity and thereby influence biochemical pathways. In allosteric enzymes, regulatory molecules act at sites separate from the active site, linking molecular recognition to pathway control. This structural perspective helps biology explain how metabolic processes are enhanced or inhibited without requiring a regulator to occupy the catalytic site itself.
