Specifically, there are two fatty acid tails and a phosphate group as the polar head group The phospholipid is an amphipathic molecule, meaning it has a hydrophobic part and a hydrophilic part The fatty acid chains are hydrophobic and cannot interact with water, whereas the phosphatecontaining head group is hydrophilic and interacts with waterIn each of the examples listed above, and in many more examples in nature (Fig1), specialized biomolecules, such as proteins, peptides, deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and polysaccharides, have been found or are thought to play a critical role in directing the formation of these hierarchically assembled inorganicAn example of a hydrophobic group is the nonpolar methane molecule Among the hydrophilic functional groups is the carboxyl group found in amino acids, some amino acid side chains, and the fatty acid heads that form triglycerides and phospholipids
Taking inspiration from the structure of diatom algae frustules and motivated by the need for new detecting strategies for emerging nanopollutants in water, we analyze the potential of nanoporous silica tablets as metering devices for the concentration of biomolecules or nanoparticles in water The concept relies on the different diffusion behavior that waterAll of them share, in addition, a fundamental relationship between structure and functions, which also involves the environment in which the biomolecule takes place for example, lipids have a hydrophobic side, that is, that repels water , so they are usually organized in the presence of it so that the hydrophilic ends (attracted by water) are in contact with theExamples of carbohydrates are cane sugar, glucose, starch, etc Most of them have a general formula, Cx(H2O)y, and were considered as hydrates of carbon from where the name carbohydrate was derived For example, the molecular formula of glucose (C6H12O6) fits into this general formula, C6(H2O)6 But all the compounds which fit into this formula

Since many biomolecules are either polar or charged, water readily dissolves these hydrophilic compounds Water is a poor solvent, however, for hydrophobic molecules such as lipids Nonpolar molecules experience hydrophobic interactions in water the water changes its hydrogen bonding patterns around the hydrophobic molecules to produce a cageBiological membranes are mainly composed of two biomolecules, lipids and proteins The spatial conformation of lipids is in the form of a bilayer, with the hydrophobic tails pointing inwards, and the hydrophilic heads pointing outwards The membrane is a dynamic entity and its components experience frequent movements ReferencesBiomolecules There are four basic kinds of biological macromolecules carbohydrates, lipids, proteins, and nucleic acids These polymers are composed of different monomers and serve different functions Carbohydrates molecules composed of sugar monomers They are necessary for energy storage

Nanoparticle–biomolecule interactions can be quite unlike those of bulk material of the same composition because the nanoparticle's effective surface charge, stability, solubility, and hydration are greatly affected by the local milieu's pH, ionic strength, temperature, and organic/molecular composition (eg, proteins, lipidsIn water, many spontaneously arrange themselves in such a way that the hydrophobic ends of the molecules are protected from the water, while the hydrophilicPhosphate group Hydrophilic molecules, are those which has the tendency to dissolve readily in water DNA is a hydrophilic in nature because of phosphorous present in phosphodiester bonds which has negative charge due to surplus electron
