L-Ribose Fischer Projection. Ribose is a simple sugar and carbohydrate with molecular formula C 5 H 10 O 5 and the linear-form composition H−(C=O)−(CHOH) 4 −H. The naturally occurring form, d-ribose, is a component of the ribonucleotides from which RNA is built, and so this compound is necessary for coding, decoding, regulation and expression of genes.
M phase See mitosis. macromolecule Any very large molecule composed of dozens, hundreds, or thousands of covalently bonded atoms, especially one with biological significance. . Many important biomolecules, such as nucleic acids and proteins, are polymers consisting of a repeated series of smaller monomers; others such as lipids and carbohydrates may not be polymeric but are nevertheless large ...
Examples of monosaccharides are the hexoses, glucose, fructose, Trioses, Tetroses, Heptoses, galactose, pentoses, ribose, and deoxyribose. Consumed fructose and glucose have different rates of gastric emptying, are differentially absorbed and have different metabolic fates, providing multiple opportunities for two different saccharides to ...
The “spacing effect” refers to a phenomenon whereby learning, or the creation of a memory, occurs more effectively when information, or exposure to a stimulus, is spaced out.
Glucose circulates in the blood of animals as blood sugar. [5] [7] The naturally occurring form is d-glucose, while its stereoisomer l-glucose is produced synthetically in comparatively small amounts and is less biologically active. [7] Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose ...
Corn syrup – sweet syrup produced from corn starch that may contain glucose, maltose and other sugars. Date sugar [1] Dehydrated cane juice [1] Demerara sugar [1] Dextrin [1] – an incompletely hydrolyzed starch made from a variety of grains or other starchy foods. Dextrose [1] – same as glucose, dextrose is an alternative name of glucose
D-Ribose pyranase is an enzyme that catalyzes the interconversion of β-D-ribopyranose and β-D-ribofuranose. [1] This enzyme is an isomerase that has only been found in bacteria and viruses . It has two known functions of helping transport ribose into cells and producing β- D -ribofuranose, which can later be used to make ribose 5-phosphate ...
A "prolific and chilling" sex abuser from Northern Ireland has been sentenced to 27 years in prison. David John Andrews, 55, with an address at Maghaberry Prison, pleaded guilty to 130 charges of ...
