Biochemistry is the study of the chemical processes in living organisms. It deals with the structures and functions of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other bio-molecules SOME CONCEPT ON BIOCHEMISTRY The most abundant molecule in the cell is Water (H2O). Roughly 70% of a cell consists of water. Inorganic molecules in the cell are: Sodium chloride (NaCl), potassium chloride ( [...]
FORMATION OF THREE GERM LAYERS All the embryonic germ layers originate from the epiblast, which divides into the endoderm, mesoderm, and ectoderm by a process called gastrulation. Christian Heinrich Pander (1794-1865) first identified this three layered organization in the blastoderm of embryonic chicks. In the process of gastrulation, a primitive streak first appears on the dorsal surface of the epiblast. As cells mov [...]
