carbohydrates

FACTS
utilization is a function of yeast genetics
glucose inhibits the transport of maltose and maltotriose in lager yeasts

SUGARS IN ORDER OF YEAST PREFERENCE
glucose (diffuses through cell wall)
fructose (diffuses through cell wall)
sucrose (converted to glucose and fructose by invertase in cell wall)
maltose, maltotriose (transported through cell wall, then converted to glucose)
