Biomolecules
Carbohydrates
Optically active Polyhydroxy aldehydes or ketones or the compounds which produce such units on hydrolisis
Hydrolysis
-
Ogliosaccharides
On hydrolisis, give 2-10 units of monosaccharides
-
-
-
Polysaccharides
On hydrolisis, they give more than ten units of monosaccharides

Proteins
Complex nitrogenous organic molecules which are essential for growth and maintenance of body. They are polymers of a-amino acids which are linked by peptide bonds

Classification
Shape
Fibrous
Long fibre like structure
Held together by hydrogen bonding
Insoluble in water
keratin(hair), myosin(muscles)
Globular
Spherical shape
Soluble in water
snake venom, hemoglobin,
fibrinogen(gets converted into fibrin(fibrous) during blood clotting)
Structure
-
Tertiary
3d shape of protien molecule
Results in twisting, bending and folding of helix structure
-
Denaturation
Change in physical and biological properties due to change in temperature, pH but no change in chemical composition
2 and 3 are destroyed but 1 is unaffected
