BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A monosaccharide containing an aldehyde group is therefore referred to as an aldose; those which contain a ketone group are ketoses. A three-carbon sugar is called a triose (an aldotriose or ketotriose). Sugars with four, five or six carbon atoms are termed tetroses, pentoses or hexoses respectively.

Detailed explanation-2: -The monosaccharides can be divided into groups based on the number of carbon atoms in the molecules, thus: trioses have 3-C atoms, tetroses have 4-C atoms, pentoses have 5-C atoms, and hexoses have 6-C atoms.

Detailed explanation-3: -Ribose is a single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules.

Detailed explanation-4: -The pentose sugar contains five carbon atoms.

Detailed explanation-5: -Arabinose is pentose monosaccharide while glucose, fructose and galactose are hexose sugar.
