BIOCHEMISTRY REVSION PROTIEN Question (1): Define and distinguish primary structure‚ secondary and tertiary structures of proteins. Protein Structures: Primary structure Primary structure of protein is its unique sequence of amino acids forming its polypeptide chain. The primary structure of a protein is starting from the amino-terminal (N) end to the carboxyl-terminal (C). Secondary structure Most proteins have segments of their polypeptide chain repeatedly coiled of folded in patterns

*What is Biochemistry?* * Biochemistry also known as Chemistry of life is the study of chemical substances and vital processes occurring in living organism. Biochemistry governs all living organisms and living processes. * Study of chemical processes in living organisms‚ including‚ but not limited to‚ living matter. * Biochemistry is the science dealing with the chemical composition and chemical reactions happening within‚ and between the living cells of all organisms. → The

precaution during these experiments‚ you should be extremely careful since these organic compounds are highly volatile (they evaporate easily) and are extremely flammable. The Bunsen burner‚ or other sources of flames‚ will not be used in the laboratory‚ unless expressly directed by the instructor (for the combustion part of this experiment‚ you will ignite your hydrocarbons using a match). All waste chemicals will be disposed of in the appropriate waste containers. The following experiments

Jordan Wong Schiefer Acc Bio Block 6 11/15/12 Unit 4 Biochemistry relates to all things living because biochemistry makes up everything living. The atoms that make up the cells within our body are a part of biochemistry. There is carbon in every living thing and carbon based molecules are a part of biochemistry. Unit 4 describes the biochemistry in all living things. It explains the atomic structure and ions‚ properties of water and pH‚ organic molecules‚ chemical reactions and enzymes.

Title Biochemical Analysis of Blood Abstract Introduction After blood is collected from a patient it is analysed to check the fragments present and the fluid which will either be plasma or serum. After plasma is separated from blood it recollects the fibrinogen which in turn helps in clotting however serum is the portion of blood which remains after the fibrinogen is removed. Serum contains approximately 6-8% of the proteins which make up blood however plasma creates up to 55% of blood

Aim: To verify the buffering capacity of a phosphate solution using a pH meter and construct a titration curve of an amino acid to determine the pka values of its ionisable groups to identitfy an unknown amino acid. Method: The ratio of [HPO42-] to [H2PO4-] required to produce buffer solutions at pH values 5.9‚ 6.9 and 7.9 were calculated. 0.1M of H2PO4- and 0.1M HPO42- were used to mix appropriate volumes to 25mL of each of the buffer solutions. The calibrated pH meter was used to measure
