I got two hours of sleep a day, which is not enough, although four hours would be sufficient. In order to get more sleep this time I'm going to try to reduce the amount of air-traffic control communication that I have to do, so that I'm not constantly on the radio. NOVA: Your last flight lasted a little over six days.
Alpha and beta glucose differ in stereochemistry at one single carbon. In the alpha-form, a bulky group is in a so-called axial position, and in the beta-form, the group is in a more favourable equatorial position. These different positions lead to different bonds in polysaccharides, giving rise to a need for different enzymes to digest them.
1 Glucose is formed from the digestion of starch, dextrin, maltose, sucrose and lactose from the foods we eat. 2  From the conversion of fructose and galactose. 3  The three monosaccharidesâfructose, galactose and glucoseâshare the same chemical formula..2 Salivary Carbohydrate Digestion. Disaccharides and polysaccharides must be digested before the body can use them, while monosaccharides do not require digestion. For this reason, as well as for other reasons (to be discussed in depth later in this lesson), our best source of carbohydrates is from fruits.
