Lipids

=
Lipids are compounds which are not soluble in water. They are hydrophobic, this term means "water fearing". Lipids are used to store long term energy, insalution, protection against physical shock, protection against water loss, hormones, and phospholipids. Lipids are composed of Carbon, Hydrogen, and Oxygen. They have a ratio of 2:1 of Hydrogen:Oxygen. They have a backbone which is Glycerol (alcohol) and three fatty acids which are long hydrocarbon chains. Overall they have one important function over the rest which is energy storage, they store energy in C-H bonds. The formation of Lipids can be called Triglycerides. Glycerol which is the backbone of the fat is an organic alcohol and it is the polar part of the entire triglyceride structure. Fatty acids are part of the carboxyl group that forms the acid, the R group is a hydrocarbon chain. Their are two types of fats Saturated fats which are long chains with no double bonds. This type of fat is solid, full of energy, and it can even block your arteries. This fat can be transmitted through animals. Unsaturated fat do have double bonds. This type of fat is liquidy, and unblocks the arteries. It is transmitted through plants and types of oils. Other types of lipids are Phospholipids they are very important for membrane structure. Waxes they are sticky and thick, they are made mostly of fatty acids and alcohol. Steroids tend to be part of the Cholesterol and Testosterone, they provide membrane support and can also be hormones. Terpenes are very essential components of pigment. Prostaglandins act like hormones in order to induce cellular and tissue responses.=====
