Presentation Transcript

  1. Proteins

  2. Made of smaller amino acids 20 amino acids… but thousands of proteins Arrangement of amino acids determines protein Used in variety of cellular functions Protein Basics

  3. Amino Acid (protein) Structure • 5 basic parts 1) Central C atom 2) Amino group (NH2) 3) H 4) Carboxyl group (COOH) 5) R group • Monomer: Amino acid • Polymer: Protein

  4. What differs between these amino acids?

  5. Amino acids are linked by peptide bonds.

  6. hydrogen bond Hemoglobin • Amino acids interact to give a protein its shape. • Proteins differ in the number and order of amino acids. • Incorrect amino acids change a protein’s structure and function.

  7. Enzymes • Types of proteins • Enzyme: Lowers the energy needed to start a chemical reaction • Breaking down food • Building proteins • Sensitive to pH, temp • Fever: enzymes lose ability to work • Very specific in actions • Ex: Amylase: Breaks down starch, in mouth, into simple sugars • Reusable
