 LIPIDS

Presentation

LIPO MEANS FAT

Definition

The lipids are natural substances happening in plant and creature tissues have a place with an exceptionally heterogeneous gathering of mixtures connected with unsaturated fats.

Lipids incorporate fats, oils, waxes, steroids, and characterized as substances having the accompanying properties:

1. They are insoluble in water (hydrophobic) however dissolvable in non-polar solvents (ether, chloroform, benzene).

2. Their essential structure blocks are unsaturated fats, glycerol, sphingosine and sterols.

3. As a rule, they can be used by the living creatures.

 Most normal lipid is fat in creatures and plants

4.Lips used to store energy in view of higher extent of C-H securities and exceptionally low extent of oxygen , oxygen store twofold how much energy when contrasted with similar measure of any carbs

Classisifcation Of Lipid

     These are named,

I. Simple Lipids

II. Compound Lipids

III. Derived Lipids

This class incorporates fats oil and waxes.

FATS AND OILS

These are esters of unsaturated fats with glycerol. (Trihydroxy liquor).

They are known as fatty oil or triacylglycerol or fat.

 A fat in fluid state called oil

Fats and oils are lighter than water and have explicit gravity of around 0.8

Glycerol+3Carboxylic corrosive - - - - - - - →Triglycerides+3CO2+3H2O

WAXES

Definition

These are esters of unsaturated fats with long chain monohydric alcohols.

RCOOH + ROH ¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬―→ RCOOR + H2O

Event

Waxes are boundless in nature as discharge of specific bugs as defensive covering of skin, for example bumble bee wax, hide of creatures, certain creature oil and whale generally made out of waxes.

Human discharge (sebum wax)

Sebum is a discharge of human skin having waxes. It assists skin with being damp and adaptable.

Plant waxes present in fingernail skin of plant cell.

COMPOUND OR COMPLEX LIPIDS

Definition

These are esters of unsaturated fats containing bunches notwithstanding a liquor and unsaturated fats.

These are sub isolated as follows:

1. Glycolipids likewise called Glycosphingolipids

These contain sphinogosine, unsaturated fat and a monosaccharide or an oligosaccharide unit.

 2. Sulphosides

These contain sphingosine, unsaturated fats, a sugar and a phosphate bunch.

3. Phospholipids

These are lipids that contain a liquor, unsaturated fat and phosphoric corrosive likewise they regularly have N-containing bases and other sustituents.

4. Lipoproteins

These are complicated of lipid with proteins.

III. Inferred LIPIDS

These incorporate unsaturated fats, glycerol, steroids, sterols, greasy aldehyde, lipid dissolvable nutrients, ketones and so on

Unsaturated fats

Definition

Hydrolysis of fats is called unsaturated fat.

Unsaturated fat contain long hydrocarbon affix attached to - COOH

Bunch.

"They are aliphatic monocarboxylic acids"

 Arrangement

 Unsaturated fat may named,

1.Saturated Fatty acids

They don't contain twofold bond.

 "Creature fat are generally soaked"

Fats containing immersed unsaturated fats are solids at room temperature

Model

Butyric corrosive C3H7COOH

2.Unsaturated unsaturated fats

They contain at least one twofold bond in their recipe.

Plant fats are generally unsaturated.

Fats containing unsaturated fats are fluid at room temperature

Types

Monounsaturated unsaturated fats

for example Oleic corrosive C18H33COOH

Polyunsaturated unsaturated fats

for example Archidonic corrosive C19H31COOH

STEROIDS

An enormous number of mixtures found in nature happening in nonsaponifiable part of lipids have a place with the class of mixtures called steroids.

STEROLS

A sub gathering of steroids is sterols which contain at least one - OH gatherings and no carbonyl and carboxyl gatherings; their names end in - old.

Models

Some of regular compound having a place with steroids are cholesterol, ergosterol, bile acids, male and female sex chemicals and the chemicals of adrenal cortex.

CHOLESTEROLS

It is most bountiful creature sterol.

It happens in creature tissues generally bountiful in the adrenal organ followed by sensory system. Ordinary plasma level reaches from 150 to 220mg/dl.

Approximately 140 grams of cholesterol might be available in a grown-up person.

It likewise present in plasma layers of tissue cells and in plasma lipoproteins.

Elements OF LIPIDS

Energy source

They are great wellspring of energy.

Transporter of fat - dissolvable nutrients

 Lipid in food additionally goes about as a transporter of fat-solvent nutrients and healthfully fundamental unsaturated fats.

Dietary Lipids

The dietary lipids decline gastric motility and have a high satiety esteem.

Solidness

Muscle versus fat gives physical dependability to organs like kidney. At the point when an individual gets thinner quickly, his kidney is at risk to become drifting kidneys.

Great supply

Fats are great supply in the body. Fat tissue is the most appropriate for this reason because of its tiny water content.

Protecting Effect

Lipids apply a protecting impact on the sensory tissue.

Indispensable part

Lipids are essential piece of cell cellular material and cell films.

Forerunner

A few lipids go about as forerunners of vital physiological mixtures .for example cholesterol is forerunner of steroid chemicals.
