Free notes of Biomolecules short revision part 1

Biomolecules Polysaccharide are not sweet in taste. All monosaccharides are reducing sugar. Monosaccharides are starting from carbon number 3. Starch contain amylose and amylopectin amylose contain bonding between c1 -c4 and amylopectin has c1-c6 bonding in their structure. Monomers: a)Lactose : 1) beta -D galactose 2)beta - D glucose. ...

Free notes of surface tension

Surface tension. Intermolecular forces:- The forces of attraction and repulsion between their molecules . These forces ,are called intermolecular . Their is to forces 1) cohesive force. 2) adhesive force. Cohesive force:- the force of attraction between 2 molecules of same substance called as cohesion. Adhesive force:- the force of attraction and repulsion between the two different substance like liquid and solid ,solid with gas etc. is called adhesion. Range of molecular forces:- The maximum distance between 2 molecules upto which intermolecular forces are effective (also called as short range forces). Distance (10 to the power -9). Sphere of influence :- an imaginary sphere drawn with given molecule as centre and radius equal to the molecular range . Surface film :- The layer of surface of liquid whose thickness is about equal to range of molecular attraction. Surface energy :- when a molecular is taken from the inside to the surface layer work...
