Milk forms cottage cheese when: a. the triglycerides in milk are lyophilized to fatty acids and glycerol by amylose b. probiotic bacteria ferment lactose sugar to lactic acid c. the pH is lowered below pH 4.6 d. the salt bridges stabilizing the functional 3-dimensional structure of casein proteins are disrupted e. sunflower oil is emulsified by the lecithin in egg white albumen
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.

Cheese was first introduced as a way of preserving the nutrients of milk. It is the fresh product obtained after coagulation of milk and whey separation. Apart from milk, cream buttermilk or a mixture can also be used. It is mainly the product of selective concentration of milk.
Thousands of cheese varieties have evolved that are characteristic of different regions of the world.
