Question

Q1. Write economic importance of secondary metabolites ?
Q2. What are nuclesoides and nucleotides?
Q3. Mention different types of polysaccharides ?​

Answer 1

Answer:

1- Secondary metabolites of plants. Plant secondary metabolites represent highly economically valuable products. These are used as high value chemicals such as drugs, flavors, fragrances, insecticides, dyes, etc.

2- Nucleosides have a nitrogenous base and a five-carbon carbohydrate group, usually a ribose molecule (see Chapter 2). Nucleotides are simply a nucleoside with one or more phosphate groups attached (Figure 4-1). The resulting molecule is found in ribonucleic acid or RNA.

3-

Explanation:

Sometimes known as glycans, there are three common and principal types of polysaccharide, cellulose, starch and glycogen, all made by joining together molecules of glucose in different ways
