What are the expected products of hydrolysis of Lactose?

The hydrolysis reaction is a chemical reaction which involves rupture of bonds between two molecules using water. The water molecule in this reaction acts as a nucleophile. Lactose is a carbohydrate molecule which is also known as disaccharide. Lactose on hydrolysis gives galactose and glucose as the products.

Give an example of aldohexose.

Aldohexose: A monosaccharide whose molecular structure contains both an aldehyde (an aldose) and six carbons (a hexose). Examples of an aldohexose is glucose. Glucose is a one of the products of photosynthesis in plants and other photosynthetic organisms. It also serves as an important metabolic intermediate of cellular respiration.

Beri-beri occurs due to the deficiency of which vitamin?

Beriberi is a disease caused by a vitamin B-1 deficiency, also known as thiamine deficiency . There are two types of the disease: wet beriberi and dry beriberi. Wet beriberi affects the heart and circulatory system.

What is the three-letter symbol of the amino acid, Proline?

The three-letter symbol of the amino acid, Proline is Pro. Proline is an organic acid, although it does not contain the amino group - NH 2 but is rather a secondary amine. Proline is the only proteinogenic secondary amino acid which is a secondary amine, as the nitrogen atom is attached both to the α-carbon and to a chain of three carbons that together form a five-membered ring.

Write the source of vitamine A.

Vitamin A is critical for vision as an essential component of rhodopsin, a protein that absorbs light in the retinal receptors, and because it supports the normal differentiation and functioning of the conjunctival membranes and cornea. Vitamin A also supports cell growth and differentiation, playing a critical role in the normal formation and maintenance of the heart, lungs, kidneys, and other organs. The following are the sources of vitamin A, they are cheese, eggs, oily fish, fortified low-fat spreads, milk and yoghurt. Vitamin A is fat soluble, but not water-soluble.

What happens when glucose is treated with the following reagent? Bromine

Glucose gets oxidised to six carbon carboxylic acid (gluconic acid) on reaction with a mild oxidising agent like bromine water. This indicates that the carbonyl group is present as an aldehyde group.

What happens when glucose is treated with the following reagent? HI

When D -glucose is heated with H I for a long time, n -hexane is formed. This shows that all the six-carbon atoms are linked in a straight chain.
