2016 FV All tissues have some capability for synthesis of the nonessential amino acids amino acid by remodeling and the conversion of nonamino acid carbon skeletons into amino acids and other derivatives that contain nitrogen However the liver is the major site of . Over the past decade an ever growing arsenal of techniques has helped researchers dissect the innermost secrets of the cell and develop new ways to detect and attack disease These techniques also have been used to produce vast amounts of once rare d C483 Spring 2013. 1.

Biochemistry . Biochemistry. is the application of chemistry to study biological processes at the cellular and molecular level.. Biochemistry is also concerned with the study of the structure and function of cellular components, such as proteins, carbohydrates and lipids.. Assist.Lecturer. . Aseel. . Ghassan. . Daoud. M.Sc. In pharmacy/ Clinical laboratory sciences. What is urea?. Urea is the main end product of protein metabolism.. It is formed by removal of amino group from amino acids in liver and excreted in urine.. 1. What is Biochemistry?. Biochemistry = chemistry of life. . Biochemists use physical and chemical principles to explain biology at the molecular level.. Basic principles of biochemistry are common to all living organism. building blocks for protein synthesis. precursors of nucleotides and heme. source of energy. neurotransmitters. precursors of neurotransmitters and hormones. Outline of amino acid degradation. The liver is the major site of degradation for most amino acids, but muscle and kidney dominate the degradation of specific ones. . §. 3.4a Protein Degradation. §. 3.4b Amino Acid Breakdown. §. 3.4c Urea .
