Monosaccharides (from Greek monos: single, sacchar: sugar), also called simple sugars, are the simplest forms of sugar and the most basic units from which all carbohydrates are built. Chemically, monosaccharides are polyhydroxy aldehydes with the formula H-[CHOH] n-CHO or polyhydroxy ketones with the formula H-[CHOH] m-CO-[CHOH]
Saccharin, also called saccharine, benzosulfimide, or E954, or used in saccharin sodium or saccharin calcium forms, is a non-nutritive artificial sweetener. [ 1 ] [ 5 ] Saccharin is a sultam that is about 500 times sweeter than sucrose , but has a bitter or metallic aftertaste , especially at high concentrations. [ 1 ]
A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. Organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms.
Carbohydrate synthesis is a sub-field of organic chemistry concerned with generating complex carbohydrate structures from simple units (monosaccharides). The generation of carbohydrate structures usually involves linking monosaccharides or oligosaccharides through glycosidic bonds, a process called glycosylation. Therefore, it is important to ...
Such non-sugar sweeteners include saccharin, aspartame, sucralose and stevia. Other compounds, such as miraculin , may alter perception of sweetness itself. The perceived intensity of sugars and high-potency sweeteners, such as aspartame and neohesperidin dihydrochalcone , are heritable, with gene effect accounting for approximately 30% of the ...
The DNA of a prokaryotic cell consists of a single circular chromosome that is in direct contact with the cytoplasm. The nuclear region in the cytoplasm is called the nucleoid. Most prokaryotes are the smallest of all organisms, ranging from 0.5 to 2.0 μm in diameter. [1] [page needed] A prokaryotic cell has three regions:
A1c is of particular interest because it is easy to detect. The process by which sugars attach to hemoglobin is called glycation and the reference system is based on HbA1c, defined as beta-N-1-deoxy fructosyl hemoglobin as component. [4] There are several ways to measure glycated hemoglobin, of which HbA1c (or simply A1c) is a standard single ...
Troshin showed that cell water decreased in solutions of galactose or urea although these compounds did slowly permeate cells. Since the membrane theory requires an impermanent solute to sustain cell shrinkage, these experiments cast doubt on the theory. Others questioned whether the cell has enough energy to sustain the sodium/potassium pump.
