Disaccharides and Polysaccharides

Science > Chemistry > Biomolecules > Disaccharides and Polysaccharides In the last article, we have studied monosaccharides. In this article, we shall study disaccharides and polysaccharides. Disaccharides: Di-saccharides on hydrolysis give two molecules of monosaccharide. They on hydrolysis with dilute acids or enzymes yield two molecules of either the same or different monosaccharides. e.g. Cane sugar (Sucrose) […]

Glucose and Fructose

Science > Chemistry > Biomolecules > Glucose and Fructose In the last article, we have seen what are carbohydrates and how are they classified. Based on hydrolysis behaviour the carbohydrates are classified into three types. a) Mono-Saccharides b) Oligo-Saccharides and c) Poly-Saccharides. In this article, we shall study monosaccharides in detail particularly glucose and fructose. […]

Carbohydrates

Science > Chemistry > Biomolecules > Introduction to Carbohydrates All those simple or complex organic and inorganic substances found in different living forms are collectively called as biomolecules. Biomolecules can be grouped into two types micro and macromolecules. The micro molecules have moderate to low molecular mass.  e.g. sugars, amino acids, and their derivatives, vitamins, […]

Nucleotides

Science > Biology > Gene its Nature, Expression and Regulation > Nucleotides In this article, we shall study structural units of nucleic acid called nucleotides. In 1869, Friedrich Miescher separated cellular substance from the nuclei of pus cell and called it ‘Nuclein’. Due to acidic nature, the substance is further called as nucleic acid. There are […]

Genetic Material

Science > Biology > Gene its Nature, Expression and Regulation > Genetic Material DNA as Genetic Material Griffith Experiment: Background: Meischer isolated nuclein from nuclei of WBCs in 1869. Walter Sutton, Thomas Hunt Morgan established that the hereditary material lies in the nucleus in chromosomes. Chromosomes are formed of proteins and nucleic acid, DNA. For […]

Types of Genes

Science > Biology > Gene its Nature, Expression and Regulation > Types of Genes In the last article, we have studied the meaning of the term gene. In this article, we shall study types of genes. Based on the function and activity, the genes are classified as follows. Housekeeping Genes or Constitutive Genes: Housekeeping genes […]

Gene: The Concept, Characteristics, and Functions

Science > Biology > Gene its Nature, Expression and Regulation > Gene: The Concept, Characteristics, and Functions In this article, we shall the essential characters of genetic material, the meaning of the term gene, its characteristics, and its functions. Essential Features of Genetic Material: It should have the ability to store hereditary information in coded […]
