Biochemistry

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.

Amino acids and Proteins

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 …

Enzymes

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 …

Vectors

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 …

Energy coupling reaction.

Exergonic to Endergonic and vice-versa Catabolic to Anabolic and vice-versa Energy coupling: transfer of energy from one reaction to another in order to drive the second reaction. Exergonic reactions: delta G ≤ 0, spontaneous, release free energy Endergonic reactions: delta G ≥ 0, Non-sponatneous, absorbs free energy.   Example: 6th and 7th step of glycolysis
