of a mosaic of proteins imbedded into a bilayer of phospholipids. Phospholipids obtain the ability to form membranes because of the fact that it is an amphipathic molecule. This means it contains polar hydrophilic heads and nonpolar hydrophobic tails‚ which make up the hydrophilic and hydrophobic regions of the membrane. The two types of proteins found in the fluid-mosaic model are integral proteins‚ which go through the hydrophobic core of the lipid bilayer‚ and peripheral proteins‚ which are appendages

Buko Pandan is a popular Filipino Dessert; this is made using young coconut and Screwpine leaves (locally known as “Pandan”). At first glance‚ this sumptuous dessert can be mistaken for Buko Salad because of the similarity in texture and dairy ingredients used. However‚ the green gelatin which contains the aroma and flavor of the Pandan gives the distinction. This is traditionally prepared by boiling several Pandan leaves until all the juices are released. The leaves are then removed from the

Biology Assignment (Haemoglobin) Proteins are large‚ complex molecules that are made up of hundreds or thousands of smaller units called amino acids‚ which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. The sequence of amino acids determines each proteins unique structure and specific function. They play many critical roles in the cells. They can be grouped as enzymes‚ antibodies‚ messengers‚ structural components or
