Explain the structure and function of proteins in the body.
Structure of Proteins: Made of amino acids linked by peptide bonds Form polypeptides, which fold into 3D structures Protein structure levels: 1. Primary structure – Amino acid sequence 2. Secondary structure – Helices and sheets 3. Tertiary structure – 3D folding 4. Quaternary structure – Multiple polypeptide chains Functions of Proteins: Enzymes (speed up reactions, … Read more
