Document Summary
Monosaccharides - most have 3-7 carbons in the structure. Oligosaccharides - small chain (3-10 monomers) covalently attached to lipids and proteins. Polysaccharides very long chains of monosaccharides put together. Cellulose cannot digest because there is a beta bond that we do not have an enzyme for. Gets name from the three fatty acids involved. Adipocytes or adipose cells store fat for energy. Polar head group made of choline and phosphate. Dissolve in organic solvents, do not dissolve in water. Cis-fatty acid kinked" shape, liquid (oil) at room temperature. Trans-fatty acids straight composition, solid at room temperature. Many different kinds of proteins with many different functions in the body. Amino acids - amino group + carboxyl group + side chain. The amino and carboxyl are bound together by a central alpha carbon. In all proteins there is only the l" stereoisomer that exists.
