Biomolecules

277735 Inulin is a polymer of

1 glucose

2 galactose

3 fructose

4 arabinose

Explanation:

(c) Inulin is a heterogeneous collection of fructose polymers. It consists of glucosyl moiety and fructosyl moiety, which are linked by $β (2, 1)$ bonds. It is a soluble dietary fibre which is a naturally occurring oligosaccharide belonging to a group of carbohydrates known as fructans. Unlike most carbohydrates, inulin is non-digestible.
Inulin is naturally present in many different.foods such as asparagus, leek, onions, banana, wheat and garlic. Higher concentrations exist in herbs.

Biomolecules

277736 Which one of the following biomolecules is correctly characterized?

1 Lecithin - A phosphorylated glyceride found in cell membrane

2 Palmitic acid - An unsaturated fatty acid with 18 carbon atoms.

3 Adenylic acid - Adenosine with a glucose phosphate molecule.

4 Alanine amino acid - Contains an amino group and an acidic group anywhere in the molecule.

Explanation:

(a) Palmitic acid is one of the most common saturated fatty acids found in animals and plants. It has 16 carbons including the carboxyl carbon. Adenylic acid is a nucleotide consisting of adenine, ribose or deoxyribose, and a phosphate group. It is a constituent of DNA or RNA. It is also called adenosine monophosphate. Amino acids are organic acids (with carboxylic group $COOH$ ) having amino group $(- N H_{2})$ generally attached to carbon or carbon next to carboxylic group. The carbon also bears a variable alkyl group (R) or hydrogen or hydrocarbon. In alanine it is represented by methyl group.
