Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown and storage of fats for energy and the synthesis of structural and functional lipids, such as those involved in the construction of cell membranes.
A diagrammatic illustration of the process of lipolysis (in a fat cell) induced by high epinephrine and low insulin levels in the blood. Epinephrine binds to a beta-adrenergic receptor in the cell membrane of the adipocyte, which causes cAMP to be generated inside the cell.
Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...

Crocs released the clog to celebrate the 2025 All-Star game, which took place February 16. The shoe itself is game-agnostic, though, so you can rock it to show your basketball pride all year long.
WASHINGTON (Reuters) -President Donald Trump on Tuesday moved to revert to older standards for light bulbs as well as toilets, showers and other water-using appliances, a day after signing an ...
In biochemistry, a metabolite is an intermediate or end product of metabolism. [1] The term is usually used for small molecules.Metabolites have various functions, including fuel, structure, signaling, stimulatory and inhibitory effects on enzymes, catalytic activity of their own (usually as a cofactor to an enzyme), defense, and interactions with other organisms (e.g. pigments, odorants, and ...
