Unstable self-esteem is negatively viewed and research has shown that an unstable self-esteem is an important predictor for internalizing and externalizing problems. [ clarification needed ] [ 4 ] For example, they found that self-esteem variability is a predictor of social anxiety , public self-consciousness, and self-perceptions that ...
Most monosaccharides have the formula (CH 2 O) x (though not all molecules with this formula are monosaccharides). Examples of monosaccharides include glucose (dextrose), fructose (levulose), and galactose. Monosaccharides are the building blocks of disaccharides (such as sucrose, lactose and maltose) and polysaccharides (such as cellulose and ...
As r increases past 0, the black dot splits into three trajectories: the blue stable fixed point that moves right, the red stable point that moves left, and a third unstable point that stays at the origin. The blue and red are solid lines in Figure 7 (left), while the black unstable trajectory is the dotted portion along the positive x-axis.
Two common examples are cellulose, a main component of the cell wall in plants, and starch, a name derived from the Anglo-Saxon stercan, meaning to stiffen. [2] To name a polysaccharide composed of a single type of monosaccharide, that is a homopolysaccharide, the ending “-ose” of the monosaccharide is replaced with “-an”. [3]
For example, simple ribose (in RNA) has one more hydroxyl group than deoxyribose (in DNA), making the former less stable and more susceptible to alkaline hydrolysis, wherein relatively high pH conditions induce the breaking of the phosphodiester linkage between two ribonucleotides.
With few exceptions, all monosaccharides are variations on the empirical formula (CH 2 O) n, where n typically ranges from 3 to 7 . [3] Common examples include glucose, ribose, and deoxyribose. monosomy The abnormal and frequently pathological presence of only one chromosome of a normal diploid pair. It is a type of aneuploidy.

A heptose is a monosaccharide with seven carbon atoms. They have either an aldehyde functional group in position 1 (aldoheptoses) or a ketone functional group in position 2, 3 or 4 (ketoheptoses). Ketoheptoses have 4 chiral centers, whereas aldoheptoses have 5.
Fructose, an example of a ketose. The ketone group is the double-bonded oxygen. In organic chemistry, a ketose is a monosaccharide containing one ketone (>C=O) group per molecule. [1] [2] The simplest ketose is dihydroxyacetone ((CH 2 OH) 2 C=O), which has only three carbon atoms. It is the only ketose with no optical activity.
