Science / Chemistry / Lipophilic: Refers to a substance's solubility in fat. Lipophilicity can be measured by shaking the substance with a two-phase mixture of water and 1-octanol and observing the final concentrations of the substanc MORE
Science / Chemistry / Arginine: (R, C6H14N4O2) Arg An essential amino acid and building block of proteins. Arginine acts as a base under physiological conditions; the double-bonded nitrogen on the end of the side chain readily captu MORE
Science / Chemistry / Phospholipid: An ester of glycerol with two fatty acids and phosphoric acid (H3PO4) or a derivative of phosphoric acid group (like H2PO4CH2CH2N(CH3)3). Phospholipids have a hydrophilic head (the phosphate group) an MORE
Science / Chemistry / Aspartic Acid: (D,HOOCCH2CH(NH2)COOH) A nonessential amino acid* that is abundant in molasses. The carboxylic acid* group on the side chain is ionized under physiological conditions, making aspartic acid residues in MORE
Science / Chemistry / Phospholipid Bilayer: In an aqueous environment phospholipids can form a two-layered 'sandwich' with the hydrophobic lipid tails on the inside and the hydrophilic phosphate heads facing outward. These bilayers are the esse MORE
Science / Biology / Phospholipids: Asymmetrical lipid molecules with a hydrophilic head and a hydrophobic tail. Lipids with a phosphate group in place of one of the three fatty acid chains. Phospholipids are the building blocks of cell MORE
