Pentamidine is not recommended in early pregnancy but may be used in later pregnancy. [1] Its safety during breastfeeding is unclear. [3] Pentamidine is in the aromatic diamidine family of medications. [4] While the way the medication works is not entirely clear, it is believed to involve decreasing the production of DNA, RNA, and protein. [1]
Phospholipids: Phospholipids are a major component of the lipid bilayer of the cell membrane and are found in many parts of the body. [25] Sphingolipids: Sphingolipids are mostly found in the cell membrane of neural tissue. [18] Glycolipids: The main role of glycolipids is to maintain lipid bilayer stability and facilitate cell recognition. [25]
Ion channels are also classified according to their subcellular localization. The plasma membrane accounts for around 2% of the total membrane in the cell, whereas intracellular organelles contain 98% of the cell's membrane. The major intracellular compartments are endoplasmic reticulum, Golgi apparatus, and mitochondria. On the basis of ...
Citrate ion Malate ion. The citrate-malate shuttle is a series of chemical reactions, commonly referred to as a biochemical cycle or system, that transports acetyl-CoA in the mitochondrial matrix across the inner and outer mitochondrial membranes for fatty acid synthesis. [1]
(The enzymes that digest polysaccharides, by contrast, are primarily produced by the walls of the intestines.) The cells are filled with secretory granules containing the precursor digestive enzymes. The major proteases, the pancreatic enzymes which work on proteins, are trypsinogen and chymotrypsinogen. Elastase is also produced. Smaller ...
Beta blockers exert their pharmacological effect, decreased heart rate, by binding to and competitively antagonising a type of receptor called beta adrenoceptors. [1]In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. [2]
The human body rapidly clears sodium benzoate by combining it with glycine to form hippuric acid which is then excreted. [46] The metabolic pathway for this begins with the conversion of benzoate by butyrate-CoA ligase into an intermediate product, benzoyl-CoA , [ 47 ] which is then metabolized by glycine N -acyltransferase into hippuric acid.
Anatomical diagram of the renin–angiotensin system, showing the role of ACE at the lungs [11] ACE is also part of the kinin–kallikrein system where it degrades bradykinin, a potent vasodilator, and other vasoactive peptides. [12] Kininase II is the same as angiotensin-converting enzyme.
