⠀ ⠀⠀$\red\small{⚘}$$\tt\small{Proteins\:↠}$Proteins are macromolecules formed by amino acids. Proteins are large size molecules (macromolecules), polymers of structural units called amino acids. A total of 20 different amino acids exist in proteins and hundreds to thousands of these amino acids are attached to each other in long chains to form a protein.

⠀ ⠀⠀$\red\small{⚘}$$\tt\small{Polysaccharides\:↠}$Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Three important polysaccharides, starch, glycogen, and cellulose, are composed of glucose. Starch and glycogen serve as short-term energy stores in plants and animals, respectively. The glucose monomers are linked by α glycosidic bonds.

Answer 2

Proteins

❖ The term polypeptide is similar to a protein. The polypeptide with a definite function is said to bean protein.

❖ A protein is made up of 20 types of amino acid residues and hence Proteind are hetropolymers. These are biomacromolecules.

❖ Collagen is the most abundant protein in animal world and second most abundant protein in the biosphere. It is the main component of connective tissue of animals.

Polysaccharides

❖ The non-sugars which are made up of more than ten monosaccharides are called as Polysaccharides.

❖ They are polymers of monosaccharides and are macromolecules.

❖ They can be branched or unbranched.

❖ The Polysaccharides posses both reducing and non-reducing ends. The right end of a Polysaccharides is a reducing end and the left end is a non-reducing end$.$

❖ They function chiefly as for and energy stores (example : starch and glycogen) and as structural materials (example : cellulose, chitin and pectin).
