Amino acids

What is the general structure of an amino acid?

How do 2 amino acids for a dipeptide?

They join together by a condensation reaction

What is the bond in a dipeptide?

The bond between is a peptide bond

What is a primary structure in a protein?

A long chain of amino acids help by peptide bonds - each protein has a different sequence of amino acids so they have different primary structures

What is a secondary structure in a protein?

When the protein chains fold due to hydrogen bonds between -C=O and -N-H

What is a tertiary structure in a protein?

When the protein folds further due to interactions between R groups

What is a disulphide bridge?

Covalent bonds that are between sulphur containing amino acids

Definition of an enzyme?

Proteins that function as a biological catalyst which speed up chemical reactions without being changed by the reaction

Definition of an active site?

A part of an enzyme that a specific substrate can attach to

Definition of a substrate?

A molecule that takes place in a chemical reaction

What is the activation energy?

The minimum amount of energy needed for successful collisions

Definition of denature?

When the substrate no longer fits into the active site - this could be due to extreme pH or high temperature
