Glucose Homeostasis and Regulation
Glucose homeostasis is the tight hormonal regulation of blood glucose levels within a narrow physiological range to ensure constant energy supply to the brain and other tissues.
Biology Glycobiology
Glycobiology is the study of the structure, function, and biology of glycans, the complex carbohydrates that coat cell surfaces and modify proteins and lipids.
Biology Glycogen Metabolism
Glycogen is a highly branched polymer of glucose that serves as the primary short-term energy reserve in animals, stored mainly in the liver and skeletal muscle.
Biology Pentose Phosphate Pathway
The pentose phosphate pathway is an alternative route for glucose metabolism that generates NADPH for reductive biosynthesis and ribose-5-phosphate for nucleotide synthesis.
Biology Clinical Enzymology
Clinical enzymology uses measurements of enzyme activity in blood and other body fluids to diagnose disease, monitor disease progression, and assess treatment response.
Biology Coenzymes and Cofactors
Coenzymes and cofactors are non-protein components that many enzymes require for catalytic activity, serving as carriers of electrons, atoms, or functional groups.
Biology Enzyme Classification and Nomenclature
Enzymes are classified by the International Union of Biochemistry and Molecular Biology into six main classes based on the type of reaction they catalyze.
Biology Enzyme Inhibition
Enzyme inhibition is a key regulatory mechanism and the basis for many pharmaceutical drugs, with reversible and irreversible inhibition strategies.
Biology Enzyme Mechanisms of Catalysis
Enzymes accelerate chemical reactions by lowering the activation energy through several catalytic strategies including acid-base, covalent, and metal-ion catalysis.
Biology Enzyme Regulation
Enzyme activity is regulated through multiple mechanisms including allosteric regulation, covalent modification, zymogen activation, and control of enzyme quantity.
Biology Cholesterol Metabolism
Cholesterol is an essential sterol that modulates membrane fluidity and serves as a precursor for bile acids, steroid hormones, and vitamin D.
Biology Eicosanoids
Eicosanoids are signaling molecules derived from arachidonic acid that mediate inflammation, fever, pain, blood clotting, and smooth muscle contraction.
