<h2>Monosaccharides</h2>
Explanation:
Monosaccharides are the simplest form of sugars found in innumerable common food items such as honey, cane sugar, fruits
Monosaccharides are divided into two groups depending on the presence of functional groups,if aldehyde group is present then it is known aldoses and if ketone group is present then it is known as ketoses
On the basis of carbon atoms they can be classified as: triose(3),tetrose(4),pentose(5),hexose(6) and so on
a. erythrose : tetrose ketose-It is not correctly paired because erythrose is a tetrose monosaccharide which has one aldehyde group hence is an aldose
b. dihydroxyacetone : triose ketose-It is correctly paired;it is an aldose-ketose pair
c. erythrulose : tetrose aldose-It is not correctly paired because erythrulose is a tetrose monosaccharide having ketone as functional group hence is a ketose
d. fructose : hexose ketose-it is correctly paired;It is an anomer because in D-fructose carbonyl group is at C-2 hence C-2 is the anomeric carbon
e. ribose : hexose aldose-it is not correctly paired because ribose is an aldo pentose not hexose;ribose is an aldo-ketose pair
f. glyceraldehyde : triose aldose-it is correctly paired;an aldo group
1. mouth, esophagus, stomach, small intestine, large intestine, rectum and anus.
2. Digestion, absorption, and elimination
6. Physical is when the food is physically broken down. (Chewing of the mouth) chemical is with the help of substances
Yes, the sample will still be a heterogeneous mixture.
A mixture contains two or more substances in any proportion.
Mixtures are divided into two main groups:
- Homogeneous mixtures: They are made up of constituents that are uniformly distributed through out the mixture.
This shows that a homogeneous mixture has only one single phase.
It is either in a solid or liquid or gaseous phase.
A typical example is air which contains a mixture of gases of the same phase.
- Heterogeneous mixtures:They are made up of different constituents that have different compositions
This means that a heterogeneous mixture can contain constituents of different or the same phase but in different quantity.
A typical example is a mixture of sand and grains. Both are of a solid phase but are combined together in different quantity even when the size of the grain is the same with the sand.
Therefore, the sample will still be a heterogeneous mixture.
