Composition, Structure, and Function of Carbohydrates

Composition, Structure, and Function of Carbohydrates

Carbohydrates include both sugars and polymers of sugars. Carbohydrates can be : Monosaccharides Oligosaccharides Polysaccharides Examples: Monosaccharides – Glucose , Fructose, Galactose. Oligosaccharide – sucrose, lactose, and maltose. Polysaccharides – cellulose and chitin Monosaccharide They are simplest carbohydrates, by polymerization, they form complex carbohydrates. They can be : Aldose Ketose Monosaccharides have asymmetric carbon centers except for Dihydroxyacetone. … Read moreComposition, Structure, and Function of Carbohydrates

Composition, Structure, And Function Of Biomolecules

Biomolecules The molecules found in the organisms are called biomolecules and they obey the same laws of physics and chemistry. Biomolecules have curious optical activity. They rotate the plane of polarisation of independent light. Organic molecules produced abiologically lack this property. Products of biological origin prefer the odd number of C atom per molecule. The cellular pool … Read moreComposition, Structure, And Function Of Biomolecules

MOLECULES AND THEIR INTERACTION RELAVENT TO BIOLOGY-1-atoms

The Atoms – Nature’s Building Material All the living organism and non-living objects are formed of matter. Atoms are the building block of matter. Atoms are generally formed of three subatomic particles: electron, proton, and neutron. Each electron has one unit negative charge and each proton has one unit positive charge, whereas a neutron has no charge. Atoms aggregate … Read moreStructure of atoms, molecules and chemical bonds
