Protein structure

• Tertiary structure describes how secondary structures are folded into three dimensions to form a functional protein molecule.
• Secondary structure refers to local folding patterns within polypeptide chains, such as alpha-helices or beta sheets.
• The primary sequence is the linear arrangement of amino acids
• Quaternary structure is the arrangement of multiple polypeptide chains (subunits) within one protein molecule, which can be identical or different subunits
• The quaternary structure determines the overall shape of the protein and its function
• Quaternary structure is the arrangement of multiple polypeptides (subunits) that make up a single protein complex.
• Proteins can be classified based on their shape and function.
• Quaternary structure involves multiple subunits coming together to form one large complex
