Abstract
The best way to start an introducrion to such a subject would be to back as just a linle and explain some term used in tile illdu tty and define the on ill of surface-active gmtsarty acids Flty Acids are aliphatic carboxylic acid with varying hydrocarbon lengths at 11 end of rhe chain joined (0 terminal carboxyl, group at the other end.
