How to analyse chemical composition? How to analyse chemical composition? Biomeological saming, what type of that? Chemical composition is present. How to analyse chemical composition? Living organisms, material, how to analyse? That is the question. For example, you take the piece of living material. Ok? It is... Captain motor, dissonazer motor, it is kept in a motor, ok? And a... And a... Triploro-istic acid... Crushing with the steel... After that... After the solution is filtered with cloth and separate that... We got two types of solutions. We got that two types of solutions. One is acid soluble solution, another one is acid insoluble solution. First one is that acid soluble solution. Another one is acid insoluble solution. Ok? So which particles are dissolved? Ok? In that acid, triploro-istic acid, so they are known as macro molecules. Which substance are dissolved in that acid solution? They are known as that, ok? Micro molecules. Which substance are not soluble in that acid? They are float, they are float, ok? On that acid solution. So they are known as that acid soluble, acid insoluble, ok? Particles... Acid insoluble particles. So this acid insoluble particles are known as that bio macro molecules. So that is known as we got that two types of that solutions. So which one is soluble in that acid? They are known as acid soluble particles. So they are known as that bio micro molecules. Which molecules are not soluble in that acid. Ok? So they are known as acid insoluble particles. They are known as that bio macro molecules. So in this... As in insoluble particles are bio macro molecules. So this bio macro molecules generally fatty acids.
