Biochemistry‚ sometimes called biological chemistry‚ is the study of chemical processes within‚ and relating to‚ living organisms.[1] By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism‚ biochemical processes give rise to the complexity of life. Over the last 40 years biochemistry has become so successful at explaining living processes that now almost all areas of the life sciences from botany to medicine are engaged in biochemical research

Isomers are molecules that a) react readily with one another b) have the same molecular formula c) have different molecular masses d) differ in the number of unsaturated bonds e) must contain the same functional group 3. In living organisms‚ buffers do which of the following? a) prevent charged particles from entering cells b) neutralize the effect of enzymes c) maintain pH in the cells within a narrow range‚ allowing enzymes to function d) allow the pH

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

Title:Identification of Amino Acids and Proteins Introduction : Amino acids are molecules containing an amine group(NH3)‚ a carboxylic acid group(R-C=O-OH) and a side-chain( usually denoted as R) that varies between different amino acids. The key elements of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form in a biologically functional way. A polypeptide is a single

from the simple elements and compounds on the Earth’s surface. Biochemistry asks how the remarkable properties of living organisms arise from the thousands of differ-ent lifeless biomolecules. When these molecules are iso-lated and examined individually‚ they conform to all the physical and chemical laws that describe the behavior of inanimate matter—as do all the processes occurring in living organisms. The study of biochemistry shows how the collections of inanimate molecules that consti-tute

1) A peptide‚ KKDSRHSTTR is tightly bound to a negatively charged ion exchange column. The column is washed with a pH 7.2 HEPES buffer (50 mM) and the peptide does not elute. Suggest two ways that you can change the buffer that will make the peptide elute from the column. 2) What amino acid(s) is/are involved in crosslinking polypeptide chains. How can these crosslinks be cleaved and prevented from reforming? 3) A polypeptide is subjected to the following degradative techniques results

*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
