IB Biology 2.4 Proteins

A protein is a large, complex molecule made up of amino acids that performs various functions in the body, including structural support, transport, and catalysis.

Three bases of DNA code for one amino acid.

Ribosomes are the cellular structures where amino acids are linked together to form polypeptides.

A polypeptide is a chain of amino acids linked together by peptide bonds, which folds into a functional protein.

The genetic code is the set of rules by which information encoded in genetic material is translated into proteins.

A proteome is the entire set of proteins expressed by a genome, and it is unique to each individual.

Amino acids are organic compounds that serve as the building blocks of proteins.

Collagen provides structural support in connective tissues, skin, and bones.

Most organisms use the same 20 amino acids, but there are exceptions.

Protein folding is crucial for the protein's function, as the specific shape determines how it interacts with other molecules.
