Document Summary
Memorize how to draw glycerate, glyceraldehyde and glycerol. Interconversion of linear and ring forms of a monosaccharide: Depending on the orientation of the aldehyde group when the ring closes, get either oh group down (alpha form) or oh group up (beta form) of d-glucose. Formation of a glycosidic bond: 2 monosaccharides linked through condensation. Maltose = 2 alpha-d-glucose (1-4 alpha glycosidic bond). Lactose = 1 beta-d-galactose + 1 alpha-d-glucose (1-4 beta glycosidic bond). One of the most abundant molecules in nature. Beta glycosidic linkage has a diagonally linked bond between monomers when draw 2-d. Alpha glycosidic linkage is a direct bond between monomers. Hydrophobic (water-insoluble) biomolecules that are highly soluble in organic solvents, such as chloroform (chcl3) Fatty acid: long hydrocarbon chain that terminates in a carboxylic acid group. 14 - 24 carbons always an even number. One of fatty acids in triglyceride is replaced by a phosphate-containing compound.
