Document Summary

Glycerol molecules with 2 fatty acids chains with ester linages. Tails are hydrophobic (basic), head is hydrophilic (hydrophilic) Forms spontaneously because of the amphipathic nature of (1) phospholipid (hydrophobic part goes together and face inwards). Held together by hydrophobic interactions- van der walls. Have short lived positive and negative charge because there are electrons moving around constantly. There are lots of these interactions so the bond all together is super strong. Proteins do most of the work besides being a structural. Hydrophilic because they exist in aqueous environment (1) Integral protein- e(cid:373)(cid:271)edded i(cid:374)to (cid:373)e(cid:373)(cid:271)ra(cid:374)e. it"s a tra(cid:374)s(cid:373)e(cid:373)(cid:271)ra(cid:374)e protein so it goes all the way through and sticks out both sides.
