Four different groups are attached to the central carbon atom (. We live in a human-centric world.. Life exists outside our box.. Subtitle. Text. Shock & Holland (2007). For example, there is life deep down on the ocean floor.. C-DEBI . (Center for Deep Energy Biosphere Investigations). Chapter 30, . Stryer. Short Course. Overview. Amino Acid Catabolism. Nitrogen removal. Urea Cycle. Metabolism of carbon backbone. Amino acid catabolism. Amino acids . from diet or protein turnover. Salvaged for use in proteins or catabolized. Contains . carbon, hydrogen. , oxygen, and nitrogen. Remember carbohydrates and lipids contain carbon, hydrogen, and oxygen – SO protein adds . nitrogen. Some proteins also contain sulfur, iron. , copper, phosphorus, or . Richard D. Howells, PhD. Dental Biochemistry Lecture 25 . 2. Learning Objectives. To distinguish between phenylketonuria (PKU) caused by phenylalanine hydroxylase (PAH) defect and PKU caused by defect in . What to Know. What is the Metabolic Fate of Ammonium?. How is Escherichia coli Glutamine Synthetase regulated?. Understand general ways that organisms synthesize amino acids. Know the definition of essential versus nonessential amino acids. Approximately 75% are reutilized.. The excess nitrogen forms urea.. Proteins represent 10-15 % of total energy supply.. Digestion and Absorption of Proteins.. The . α. -amino group of many amino acids is transferred to . 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 . GLYCINE. Glycine is the . simplest . amino acid. Chemically it is “. amino acetic acid. . ".. It is non-essential amino acid and can be synthesized in . tissues. . Though it is non- essential but it is an important amino acid as it forms many biologically important compounds in the body.. Unit-1. P.G.. 25.09.2020. Oxidative Deamination .
