PPT-Amino Acid Side Chains There are 20 different types of amino acids. Each one has identical

backbone   atoms see aminoAcids1  but a unique set of side chain atoms Its the side chains that make the 20 amino acids different from each other  1 Use the three identical backbone pieces and three unique side chain pieces below to construct three amino acids in the space to the right. What are amino acids?. Amino acids are the building blocks of proteins.. In the body, they exist as zwitterions.. Zwitterions can behave as both an acid or a base.. Today we will:. Study . the acid-base properties of amino acids, . (Foundation Block). Dr. Ahmed Mujamammi. Dr. . Sumbul. . Fatma. Learning outcomes. What are the amino acids?. General structure.. Classification of amino acids.. Optical properties.. Amino acid configuration.. Hydrogen bonds in the tertiary . protein structure. Many amino acids contain groups in the side chains that have a hydrogen atom attached to either an oxygen or nitrogen atom. Hydrogen bonding can occur between such groups.. When an amino acid with positive and negative charges is overall neutral in charge, it is said to be at its . isoelectric point (. pI. ). .. . Ball-and-stick model of glycine at its . pI. of 6.0.. Plants and bacteria produce all of their amino acids using NH. 4. +. and NO. 3. –. .. Humans can synthesize 9 of the 20 amino acids found in their proteins.. Nonessential amino acids are synthesized in the body, while essential amino acids must be obtained from diet.. amine group. Draw. a carboxylic acid group.

Peptide bond formation. : . α-carboxyl group of one amino acid (with side chain R1) forms a covalent peptide bond with α-amino group of another amino acid . ( . with the side chain R2) by removal of a molecule of water. The result is : Dipeptide ( i.e. Two amino acids linked by one peptide bond). By the same way, the dipeptide can then forms a second peptide bond with a third amino acid (with side chain R3) to give .
