química colesterol y gras-insulina

colesterol:
(OH)_{2}-Hex[ -O- | -C=C-O-C=C- ]-O_{6}-Hex[ -O- | -C=C-O-C=C- ]-(OH)_{2}
4 para-destructores + 2 para-constructores = 2 para-destructores


gras-insulina:
(OH)_{2}-Hex[ -O- | -C=C=C-O-C=C=C- ]-O_{6}-Hex[ -O- | -C=C=C-O-C=C=C- ]-(OH)_{2}
4 para-destructores + 6 para-constructores = 2 para-constructores
