- Acollagen: amino acid; glycogen: $\alpha$-glucose; cellulose: $\beta$-glucose
- Bcollagen: $\alpha$-glucose; glycogen: $\beta$-glucose; cellulose: amino acid
- Ccollagen: $\beta$-glucose; glycogen: amino acid; cellulose: $\alpha$-glucose
- Dcollagen: amino acid; glycogen: $\beta$-glucose; cellulose: $\alpha$-glucose
