Describe and compare the building blocks, general structires and biological functions of carbohydrates lipids proteins and nucleic acids

Explanation:

Carbohydrates are basically composed of Carbon, Hydrogen and Oxygen having the general formula CnH2nOn.

There are 3 types of carbohydrates which are dependent on the number of "n"

Monosaccharides which are n>3 (Triose) are the aldose and ketose.

They are the simpleat and smallest form and they are Glucose, fructose and galactose

Disaccharides are structure of the combination of the monosaccharides by glycosidic bond and they are sucrose, lactose, maltose etc

Polysaccharides are the largest and insoluble form of carbohydrates. They are cellulose, starch, glycogen etc.

Lipids(triglycerides) are solid fats or series of repeated fats at room temperature, they are insoluble in water both soluble in some organic solvents. They are also composed of glycerides (3 molecules). Its structure is composed of two parts, the soluble part composing of the -COOH group and the insoluble part that can be saturated or unsaturated hydrocarbon chain

Saturated fats - CH3(CH2)nCOOH

Their types are phospholipids, glycolipids etc

Proteins are polymers of peptides called polypeptides. The bond linking the structure together is called a peptide bond (-CONH-). They form chains of amino acid.

There are 4 levels of protein structures and they are

The primary structure defines the basic straight chain structure of an amino acid. They form the basis of genetic mutation.

Secondary structure involves the folding of this chain into alpha helix or beta pleated.

Tertiary structure is a 3-D structure that involves the hydrophobic and Hydrophilic parts pf the structure. The hydrophobic part apreads outwards while the hydrophyllic parts curve inwards by the action of van der waals forces.

Tertiary structure in this case is the example of the Haemoglobin

Nucleic acids is the building block for RNA and DNA (ribo- and Deoxyribonucleic acid). This is composed of a nitrogenous base which can either be purine or pyrimidine bases, a ribose sugar (5- Carbon sugar and phosphate group

The bond holding the nucleotides together is called phosphodiester bond.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
