Definitions:

Hydroxyl Group

The hydroxyl group consists of an oxygen atom bonded to a hydrogen atom (-OH), commonly found in alcohols and responsible for their polar properties.

Peripheral Proteins

Proteins that are attached to the surface of the membrane and are not embedded within the lipid bilayer, playing roles in cell signaling and structure.

Covalent Disulfide Bonds

Strong chemical bonds formed between two sulfur atoms within or between polypeptide chains, important for the stability and folding of proteins.

Hydrophobic Interactions

Non-covalent bonding interactions that occur between nonpolar molecules or molecular regions, driving them together in aqueous environments.
