In vitro maturation of Xenopus oocytes and assay of maturation-promoting factor(MPF) Progesterone Sperm

Much of the catalytic power of enzymes comes from their bringing sub- strates together in favorable orientations in enzyme-substrate (ES)com- plexes. The substrates are bound to a specific region of the enzyme called the active site. Most enzymes are highly selective in their binding

Introduction A diverse group of water-insoluble (hydrophobic) compounds three types of lipids—storage or structural lipids, “bioactive” lipids

Biological Membranes and Transportpart II Passive transport: with the gradient – Water transport—aquaporins – Glucose transporters – Co-transport of chloride and bicarbonate Active transport: against the gradient – Transport ATPases – Ion channels

The term carbohydrate derives from the fact that many of them have a formula that can be simplified to (CH2O)n. Some of these compounds are chemically modified, however, and do not fit the formula due to the modification
