Chemical Component of Cell, Water, Biomolecule Mineral Ion

Cell is built by chemical components consisting of anorganic and organic components. Anorganic components are the ones coming from nature, such as mineral salts and ions. Organic components are the components produced by living organisms and consist of macromolecules(amino acid, fatty acid, nucleotide, and glucose) and macromolecules (protein, lipid, nucleic acid, and carbohydrate/ polysaccaride).
a. RNA Structure
b. DNA Structure

1. Water 
A cell contains 85%-95% of water. Water function as solved and the best diffusion media for metabolism process in cells and tissues. Water also necessary to keep balance of cell liquid pH, so that metabolism reaction involving enzyme can work. Moreover, water also has high heat capacity, and it is able to heave head well, so that water is properly used as temperature control media.

2. Biomolecule
Biomolecule compounds are divided in two types, macromolecule and micromolecule. Macromolecules are generally know In four form, protein, nucleic acid, carbohydrate, and lipid. Protein fuctions as enzyme, component of cell membrane, transportation, antibody, hormone, and cell signal. Protein and lipid form bilayer phospholipid that is necessary as component of cell membrane. Carbohydrate functions as energy source for cell, membrane and cell wall structure component, and with protein becomes components of nucleus. Nucleic acid functions as genetic factor, coenzyme, energy carrier, and protein biosynthesis contoler. The most common nucleic acid is deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)

Adenine, Guanine, Thymine, Cytosine
Adenine, Guanine, Uracil, Cytosine

3. Mineral And Ion
Mineral And ion are components of cell that are also important as well as other chemical components . For example, magnesium is one of the components of plant cell wall that makes the cell become one complete piece.
