Document Summary
Meaning that the sugar molecules made by the are the simplest forms of cho molecules (common: 6-carbon chains and form through glycosidic linkage of two monosaccharides. Carbohydrates represent about 50% of the calories consumes in north american diet. Natural enzymes are typically stereospecific enzymes of photosynthesis tend to be in a certain isomeric form. Two main dietary saccharides are: lactose and natural sugars. Complex sugars: oligosaccharides together by glycosidic bonds and polysaccharides monosaccharides which often have hundreds or thousands of units. All must have an aldehyde or ketone functional group. 6-carbons which consist of short chains of monosaccharides joined which are longer chains of 10 or more (=o) The functional carbonyl group could be either an aldehyde or a ketone. Sugars can become ring structures due to reactivity to the carbonyl group. This happens by the second lowest carbon group bending around and attacking the carbonyl carbon. This is non-enzymatic and there is rapid equilibrium.
