The correct Answer is:
To solve the question regarding the structural relationship of cyanophycean starch found in blue-green algae (cyanobacteria), we can break down the information as follows:
### Step-by-Step Solution:
1. **Understanding Blue-Green Algae**:
- Blue-green algae, also known as cyanobacteria, are photosynthetic organisms that can produce their own food using sunlight, similar to plants.
2. **Food Storage in Blue-Green Algae**:
- These organisms store food in the form of granules. There are two types mentioned: alpha granules and beta granules.
- Alpha granules consist of cyanophycean starch, while beta granules are made up of fat droplets.
3. **Composition of Cyanophycean Starch**:
- Cyanophycean starch is the form of starch synthesized by cyanobacteria. It is important to note that this starch is not the same as the starch produced by higher plants.
4. **Comparative Analysis**:
- The question asks about the structural relationship of cyanophycean starch. In the video, it is mentioned that cyanophycean starch is structurally related to glycogen, which is a storage form of glucose in animals.
- Additionally, it is noted that while cyanophycean starch resembles glycogen, it is different from the starch produced in plants.
5. **Conclusion**:
- Therefore, the cyanophycean starch found in blue-green algae is structurally related to glycogen, as both serve as storage forms of energy, albeit in different organisms.
### Final Answer:
Cyanophycean starch is structurally related to glycogen.

Carbohydrates play a vital role in our daily life. These are classified as monosacchrides, oligosaccharides and polysaccharides depending upon the number of smaller molecules on hydrolysis. It has been suggested that monosaccharides do not have a free aldehyde or ketonic group but have cyclic hemiacetal or hemiketal structures. D - Glucose exists in two isomeric stereoisomeric forms : alpha-D- glucose and beta-D glucose which have different positions of H and OH groups on first carbon atom. Disaccharides such as sucuose, maltose, lactose, etc., give monosaccharides on hydrolysis. Polysaccharides are starch, cellulose, glycogen, having molecular formula (C_(6)H_(10)O_(5))_(n) . Name the water insoluble component of starch.

Monosaccharides are polyhydric aldehydes and ketones which cannot be hydrolysed into simpler carbohydrates. The monosaccharides containing -CHO group are called aldoses while those containing C=O group are called ketoses. The aldehyde group is always present at C_(1) while keto group is generally present at C_(2) . All monosaccharides are oxidised by Tollen's reagent and Fehling solution and are called reducing sugars. The monosaccharide molecules may be assigned D and L-configurations depending upon whether the configuration of the molecule is related to D- or L-glyceraldehyde. If the -OH group is attached to the carbon adjacent to the -CH_(2)OH group (last chiral carbon) is on the right hand side, it is assigned D-configuration. The molecule is assigned L-configuration if the -OH group attached to the carbon adjacent to the -CH_(2)OH group is on the left. The monosaccharides contain one or more chiral carbon atoms. Pentoses and hexoses have cyclic structures furanose (five membered) and pyranose (six membered). During cyclization, C_(1) in aldohexoses and C_(2) in fructose become chiral and the newly formed -OH group may be either on the left or on the right in Fischer projection formulae. These monosaccharides, therefore, exist in two stereoisomeric forms called alpha -anomer and beta -anomer while C_(1) and C_(2) are called glycosidic or anomeric carbon. The bonds joining glycosidic carbon are called glycosidic linkages. D(+) glucose exists in two stereoisomeric forms, alpha -D- glucose and beta -D-glucose. When either of these two forms of glucose i.e., alpha-D- glucose are dissolved in water and allowed to stand, these get slowly converted into other form and an equilibrium mixture of both is formed. This process is called mutarotation. Two forms of D-glucopyranose are called
