An analysis of large molecules composed of smaller molecules called monomers

The larger biological molecules are made from smaller molecules. Polysaccharides are made from monosaccharides, proteins from amino acids, nucleic acids from nucleotides, lipids from fatty acids and glycerol.

The resulting bond is called an ester bond. In fact, fatty acids are stabilized by hydrophobic interactions. In a saturated fat the hydrophobic interactions are stronger because the fatty acid chains are able to stack very closely together, thus forming fats that are solids at room temperature.

Unsaturated fats are liquids at room temperature because the double bonds in the chain allow for kinking in the chain which prevents close stacking of the molecules. The presence of the phosphate group creates a hydrophilic end in this molecule and the fatty acid portion is hydrophobic.

This makes the phospholipids s excellent barriers as in membrane structure. STEROIDS compact hydrophobic molecules containing four fused rings and various functional groups cells use steroids as a building block for certain vitamins like vitamin D some sex hormones are steroids cholesterol is an important membrane steroid that controls cell fluidity and permeability WAXES hydrophobic molecules composed on long chain fatty acids linked to alcohols length of chain provides for pliable yet firm consistency form waterproof layers on plants No related posts.Biological molecules are macromolecules, which basically means they are polymers composed on small repeating units that have been covalently bonded together.

The exception to this is a type of lipid called triacyleglycerides or phospholipids which are relatively large molecules composed of smaller molecules bonded together.

The large molecules necessary for life that are built from smaller organic molecules are called biological are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions.

Sugar molecules have the formula (CH 2 O) n, where n is any number from 3 to 8.

For glucose, n is 6, and its formula is C 6 H 12 O 6. The formula for fructose is also C 6 H 12 O 6, but as you can see in Figure 1, the placement of the carbon atoms is different. Ester names are derived from the parent alcohol and the parent acid, where the latter may be organic or inorganic.

Esters derived from the simplest carboxylic acids are commonly named according to the more traditional, so-called "trivial names" e.g. as formate, acetate, propionate, and butyrate, as opposed to the IUPAC nomenclature .

The basic units of three of the four large molecules (carbohydrates, proteins, and nucleic acids) are composed of chains of smaller molecules (monomers) connected to form larger molecules .
