Lactic acid, also known as 2-hydroxypropanoic or milk acid, is a compound formed when glucose is broken down under certain conditions in a living creature or by some types of bacteria. In a person, for example, it is an important part of producing energy for strenuous exercise and helps with certain liver functions. During extremely intense exercise, it can buildup to excess and cause short-term burning sensations in muscles. This acid can also be found in certain dairy products, such as yogurt<span>, as well as sourdough breads and some beers and wines as a result of fermentation.</span>
Double-stranded DNA comprises of two polynucleotide chains whose nitrogenous bases are connected by hydrogen bonds
Inside this arrangement plan, each strand mirrors the different because of the anti-parallel orientation of the sugar-phosphate spines, just as the reciprocal of the A-T and C-G base pairing
The two strands of DNA are held together by means of hydrogen bonds, which permit the grouping to be “unzipped” for replication or <em>transcription</em>
<em>The 5-carbon sugars ribose and deoxyribose are important components of nucleotide, and are found in RNA and DNA</em>
