Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which category of macromolecules includes sugars and starches?
A
proteins
B
phospholipids
C
unsaturated fatty acids
D
carbohydrates
Explanation: 

Detailed explanation-1: -A long chain of monosaccharides linked by covalent bonds is known as a polysaccharide (poly-= “many”). The chain may be branched or unbranched, and it may contain different types of monosaccharides. Polysaccharides may be very large molecules. Starch, glycogen, cellulose, and chitin are examples of polysaccharides.

Detailed explanation-2: -Carbohydrates. Carbohydrates include simple sugars (monosaccharides) as well as large polymers (polysaccharides). Glucose is a hexose, a sugar composed of six carbon atoms, usually found in ring form. A starch macromolecule is a polysaccharide composed of thousands of glucose units.

Detailed explanation-3: -Carbohydrates are macromolecules called polysaccharides, meaning they are made of many sugars. The individual molecules that make up carbohydrates are called monosaccharides.

Detailed explanation-4: -Carbohydrates are essential macromolecules that are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.

Detailed explanation-5: -A starch macromolecule is a polysaccharide composed of thousands of glucose units. Glucose molecules can be added to starch by a condensation reaction. In condensation reactions, two molecules covalently bond to each other and release a water molecule.
