All about Protein – Medical | Merofuture


They are compounds of H, O, C and N.

S, Cu, pare present in some proteins.

The proteins or building molecules. The proteins are formed by number of smell units called amino-acids. Therefore protein is polymer of ominoacids.

Aminoacid + Aminoacids …… protein

  • Amino Acids: The aminoacids is hydrocarbon chin having COOH and NH2 group.
  • Macromolecules

  • Peptide bond: It is refereal as COHH to from peptide bond minimum to amino acids are requar.

Types of Protein

There are three types of protein

  1. Simple protein: This are made up of amino acids only conjugate protein this are made up of an other groups along amino acids.

e.g. globulis, albumin, glycoproteins.

  1. Derived protein: This are found by denaturation of the proteins.

e.g. Proteoses, peptones

  1. Conjugred proteins: These are the proteins formed due to the combination fo amino acids with non-protein substances. There are two different types of amino acids basedon synthesic living an organisms.
  2. Essential: This are those amino acids which are not synthised in sides in the body.
  3. Non essential amino acids: This are synthesized inside in the body. Non essential amino acids strunal shoch for the body. This are synthis size inside the body through some chemical cycle inside the body.

Function of Protein

  • Proteins are for storage, transiport of oxygen, hormones, blood ctoting structurecally etc.
  • They both protein are important are lignin organisms and spposrt veries function inside the body.

Lipids (Fats): They are pold as esters of fatty acids

Fatty acids are also called as carboxylic acids. Ester is of compound from with the reaction of carboxylic acids and alcohol.

Lipids are classification into three types.

  1. Simple Lipid: Simple lipids are ester are fatty acids and different an alcohols.

e.g. Fats, oils, waxes etc.

  1. Complex lipids: This are made up of fatty acids alcohol and other groups for example.

Glycolipid, phospholipid.

Lipoprotein                 Cho+Fa+Alcohol

  1. Derived lipids: They are derived from simple or complex lipid an hydrodysis.

e.g. steroids, cholesterol

Function of Lipid

  • They are found in seeds.
  • Fats are resulte food metewen, and animals.
  • They act as shock absorbers.
  • They prepend from various vactireall disease.
  • Some fats are required for digession.
  • Waxes propied protectude covery for nerophytic plants.

Nucleic Acids: They are present in the Neculeus of higher organisms. They are of two types. DNA & RNA

DNA = Deoxyribonucleic Acid

RNA = Ribonucleic Acid

Minerals – Micro molecules – Inorganic

Minerals they are inorganic substance which are inclual part growth and development of living or contains minerals are small quantitive are as micro nutrients.

e.g. Iron, copper, zinc, flouri Iodin etc.

those mlen which are requires micro untrients.

e.g. Microgen, phosphors, calcium, sodium, chlorine etc.

– Properties of water: Waterh is made fo hydrogen and oxygens atoms water has friangular structure having dipole.

Water is exient solbelt for number of solutes with is required for different biochemical reactions in the body.

  • Water has high specific heat.
  • The temperature of water dose not rise even different types of soliets are in a water they four – the body temperature the made.
  • Water has high latent heat i.e. to evaporate water very high temperature is requer.
  • Water is shows the property of ionizing that is (i.e.) it from and OH ions.
  • Water shows adhesive and cohes property which transport and water in the plant.

Function of water

  • It is row materials of photo synthesis in plant.
  • Water mintans the shaf of cell
  • Water helps in different plant movement. E.g. opening of flowers, stomatal movement.
