1. Amylopectin have 1 → 4 α -linkage and 1 → 6 α -linkage 2. Amylopectin have 1 → 4 α -linkage and 1 → 6 β -linkage 3. Amylose have 1 → 4 α -linkage and 1 → 6 β -linkage 4. Amylose is made up of glucose and galactose

Answer: 1. Amylopectin have 1 → 4 α -linkage and 1 → 6 α -linkage Both amylose and amylopectin are polymers of α -D-glucose, and they differ in chain structure. Amylose: unbranched, only C1→ C4 α -glycosidic links. Amylopectin: branched; C1→ C4 α -links in the chain plus C1→ C6 α -links at branch points. So option 1 is correct. No β -links occur, and galactose is not involved.

Answer: 1. Amylopectin have 1\(\rightarrow\)4 \(\alpha\)-linkage and 1\(\rightarrow\)6 \(\alpha\)-linkage

Both amylose and amylopectin are polymers of \(\alpha\)-D-glucose, and they differ in chain structure.

Amylose: unbranched, only \(\mathrm{C1\to C4}\) \(\alpha\)-glycosidic links.
Amylopectin: branched; \(\mathrm{C1\to C4}\) \(\alpha\)-links in the chain plus \(\mathrm{C1\to C6}\) \(\alpha\)-links at branch points.

So option 1 is correct. No \(\beta\)-links occur, and galactose is not involved.
