Biochemistry is the study of the chemical processes occurring in living matter. It majorly focus on the role, function, and structure of biomolecules. In general it deals with enzymes, carbohydrates, amino acids, proteins, fats, hormones, DNA, RNA, etc.
Urine is an excretory product of the body and presence of certain substances in urine reflects the metabolic state of the body. Composition 95% of volume of normal urine is due to water. Others:- Organic components – urea, urobilinogen, uric acid, amino acids, creatinine, metabolities of hormones. Inorganic components – Cations:- Na+, K+, Ca2+, NH4+ …
Living systems are made up of Proteins .They are the dehydration polymers of amino acids.Each amino acid residue is joined by a peptide linkage to form proteins. Proteins are the molecular instruments in which genetic information is expressed, Hormones, Antibodies,transporters, the lens protein, the architectural framework of our tissues and a myriad of substances having distinct …
Body proteins perform a large number of functions. One such unique function is, they act as biological catalysts (Enzymes) .They are responsible for highly complex reactions. They direct the metabolic events and exhibit specificity toward substrates, regulate the entire metabolism.Thus, they play key role in the degradation and synthesis of nutrients, biomolecules etc. The most …
A vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell, where it can be replicated or expressed. Cloning vector is a small DNA molecule capable of self-replication inside the host cell. Cloning vector is used for replicating donor DNA fragment within host cell. Vectors can replicate …
Developed by: G.N. Ramachandran in 1963 + and – + and + – and – 0 White regions: sterically disallowed for all amino acids except glycine Red regions: allowed regions namely the alpha-helical and beta-helical conformations Yellow areas: outer limit Exception: Glycine can lie anywhere
