Complex sugars or polysaccharides are composed of basic units called monosaccharides that are linked via glycosidic bonds. Glycosidic bond is formed through condensation reactions (water is released) that occur between a hydroxyl (OH) oxygen atom on one sugar and the α-anomeric form of C-1 on the other. There are are two types of glycosidic bonds:
- 1,4 alpha ( the OH is below the glucose ring)
- 1,4 beta glycosidic bonds (the OH is above the glucose ring)
Amylase is an enzyme that breaks down starch into smaller glucose molecules, it act on α-1,4-glycosidic bonds and it works in mouth where the digestion begins (salivary amylase) . Maltase breaks down maltose into glucose; sucrase, breaks down sucrose into glucose and fructose; and lactase, which breaks down lactose into glucose and galactose work in small intestine and also act on α-1,4-glycosidic bonds.
<span>When cells were first taken from Henrietta Lacks, she was suffering from cervix cancer. Henrietta Lacks was a woman whose cervix cancer cells were used as the source of the HeLa cell line nowadays used in medical research. During treatment for cervical cancer in 1951, the cells were taken without her knowledge. The cells were cultured by George Otto Gey who created the HeLa cell line.</span>
