AB Lipids  are  the  third  major  type  of  biochemical  molecule  found  in  humans.  Although  one  of  their  major  functions  relates  to  the  formation  of  biological  membranes  (phospholipids  and  cholesterol),  lipid  molecules  are  also  essential  for  energy  storage  and  transport  (triacylglycerols),  cellular  binding  and  recognition  and  other  biological  processes  (glycolipids),  signaling  (steroid  hormones),  digestion  (bile  salts),  and  metabolism  (fatty  acids,  ketone  bodies,  and  vitamin  D).  Lipid  molecules  are  mainly  hydrophobic  and  are,  therefore,  found  in  areas  away  from  water  molecules  or  are  involved  in  mechanisms  such  as  lipoprotein  complexes  that  allow  their  movement  in  and  through  water  environments.  The  smaller  hydrophilic  parts  of  lipids  are,  themselves,  important  in  formation  of  biological  membranes  and  in  the  several  specific  functions  of  lipids  and  lipid-derived  molecules.
