Biology Assessment

Molecules with a hydrocarbon chain and a carboxyl group, serving as the building blocks of lipids, can be saturated or unsaturated.

Common dietary fat form consisting of three fatty acid molecules esterified to a glycerol molecule, used for energy storage in adipose tissue.

Components of cell membranes composed of two fatty acid chains, a glycerol backbone, a phosphate group, and a polar head group, forming lipid bilayers.

Molecules with a characteristic four-ring structure, including cholesterol found in cell membranes and hormone precursors like estrogen and testosterone.

Esters of long-chain fatty acids and alcohols, hydrophobic compounds used as protective coatings in plants and animals.

Triglycerides in adipose tissue store energy for future use.

Phospholipids form the cell membrane, controlling substance movement.

Lipids, like adipose tissue, insulate and protect organs.

Some lipids act as signaling molecules regulating physiological processes.

Lipids contribute to tissue and organ structure, like myelin sheaths protecting nerve fibers.

The linear sequence of amino acids linked by peptide bonds, determined by the genetic code.

Local folding patterns stabilized by hydrogen bonds, like alpha helices and beta sheets.

The three-dimensional folding of a single polypeptide chain due to interactions between amino acid side chains.

The arrangement of multiple polypeptide subunits in a protein complex, varying from monomers to oligomers.
