DIGESTION AND ABSORPTION:- PHYSIOLOGY OF DIGESTION PHYSIOLOGY OF DIGESTION 1.DIGESTION OF CARBOHYDRATES:-   Any polyhydroxy aldehyde or ketone called carbohydrates. About 30% of starch is hydrolysed in buccal cavity by salivary amylase/ ptyalin enzyme (optimum pH=6.8) into Maltose, Isomaltose and α-dextrin. Lysozyme present in saliva acts as an antibacterial agent that prevents infections. Maltose, Isomaltose […]

VIRUS, VIROIDS,PRIONS,LICHENS VIRUSES:- Virus also contain genetic material, that could be either RNA or DNA. Apart from genetic materials, Viruses also contains proteins. Single stranded RNA (ssRNA) Virus infect plants. Either double stranded DNA(dsDNA) or double stranded RNA(dsRNA) infect animals. Contagium vivum fluidum (infectious living fluid) = by M.W Beijerinek (1898) Virus can be Crystallised
