Nucleotides and nucleic acids- the nucleotides are the monomeric units of nucleic acids.
Deoxyribonucleic acids (DNA) and Ribonucleic acids (RNA) are chain- like macro molecules that function in the storage and transfer of genetic information.
One of the major functions of proteins is their action as enzymes.
Enzymes and their kinetics are also studied elaborately under biochemistry.
Vitamins and coenzymes- Vitamins have been recognized as compounds that are essential to the health of humans and other vertebrates but cannot be synthesized by these animals and have to be obtained through the diet.
They are divided in two classes water soluble (vitamin B and C) and fat soluble(vitamin A, D, E, and K).It is the combination of biology with organic, inorganic and physical chemistry and the sciences of Molecular Biology, immunochemistry and neurochemistry.Its wide range of applications include research and development of medicine, use of chemical concepts, procedures, and techniques to study the diagnosis and therapy of disease, food sciences, dealing with the environmental problems on the chemical level etc.Each nucleotide contains three characteristic components namely a nitrogenous heterocyclic base (either a purine or pyrimidine), a pentose sugar, and a molecule of phosphoric acid.The major purines include adenine and guanine and the main pyrimidines are thymine, cytosine and uracil.Some experts also call this science Molecular Biology because it deals with cells and molecules of living things.This brief description will give you a good idea for the necessity of having Biochemistry help online.Polysaccharides contain many monosaccharide units joined in long linear or branched chains.They act mainly as the storage or structural elements in the body.They are involved in cell recognition and tissue immunity.They are categorized as simple and complex lipids according to the absence or presence of fatty acids respectively.
