What Are Metabolic Pathways?
The term 'metabolism' comes from the Greek word metabole, which means change. It refers to the total of an organism's chemical reactions. A metabolic pathway is a series of steps found in biochemical…
Introduction to biocatalysis
Biocatalysis have many advantages over chemocatalysis in the context of green chemistry, which include mild reaction conditions (physiological pH and temperature), the use of environmentally compatible catalysts (enzymes) and solvents…
Enzymes
We have a whole section where we tell you about reactions and the molecules that change in those reactions. Chemical bonds are being created and destroyed over a series of many intermediate…
Structure of DNA
Primary structure and its double helix: Sequence in which four nitrogen bases are attached to the sugar phosphate backbone of a nucleotide chain is called primary structure. Watson and crick in…
Biomolecules – Nucleosides & Nucleotides
Nucleosides: Nucleoside contains only two basic components of nucleic acids (a pentose sugar and a nitrogenous base). During their formation, 1- position of pyrimidine or 9 – position of purine moiety…
DNA Details
DNA stands for deoxyribonucleic acid. It is special, because it holds the code for every cell in your body. That's right. Every cell in your body uses DNA as an instruction…
The Nucleic Acids
The nucleic acids are the building blocks of living organisms. You may have heard of DNA described the same way. Guess what? DNA is just one type of nucleic acid. Some other types…
Secondary, Tertiary, Quatemary Structures
Secondary Structure Stretches or strands of proteins or peptides have distinct, characteristic local structural conformations, or secondary structure, dependent on hydrogen bonding. The two main types of secondary structure are…
Prostaglandins
Prostaglandins are unsaturated carboxylic acids, consisting of of a 20 carbon skeleton that also contains a five member ring. They are biochemically synthesized from the fatty acid, arachidonic acid. See…
Carbohydrate Molecules
Carbohydrates can be represented by the stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule. Therefore, the ratio of carbon to hydrogen to oxygen is 1:2:1…
