Document Summary

Fatty acid chains: fatty acids have two distinct regions long hydrophobic hydrocarbon chain, and a carboxyl group (hydrophilic) thus amphipathic, saturated/unsaturated by double bonds in the chain, phospholipids for cell membranes. Some are polar and hydrophilic, others are nonpolar and hydrophobic. Major classes of biomolecules: proteins, nucleic acids, carbohydrates and lipids, as (cid:271)io(cid:272)he(cid:373)ists (cid:449)e"(cid:396)e i(cid:374)te(cid:396)ested i(cid:374) the (cid:272)he(cid:373)ist(cid:396)(cid:455) of these (cid:373)ole(cid:272)ules p(cid:396)i(cid:373)a(cid:396)il(cid:455) have to u(cid:374)de(cid:396)sta(cid:374)d (cid:449)hat the(cid:455)"(cid:396)e (cid:373)ade of, ho(cid:449) the(cid:455) i(cid:374)te(cid:396)a(cid:272)t (cid:449)ith ea(cid:272)h other, work together, etc. The structure told them the molecular basis of heredity: simply by examining the structure and realizing its chemical implications. Proteins: structural proteins, transport proteins, motor proteins, storage proteins, and enzymes, enzymes are most common group of proteins, the(cid:396)e is(cid:374)"t a si(cid:374)gle (cid:373)a(cid:272)hi(cid:374)e that hu(cid:373)a(cid:374)s ha(cid:448)e (cid:271)uilt that is as e(cid:454)(cid:395)uisite as e(cid:374)z(cid:455)(cid:373)es. Proteins are composed of amino acids based on the genetic code: proteins are all polymers of amino acids, 20 different amino acids.
