Building blocks/stones of proteins Fundamental sub-units of proteins

amino acid

GENERAL FORMULA:

Carboxyl group = acidic properties Amino group= basic properties Chiral C= asymmetric carbon

CHARACTERISTICS

1. Optically active All amino acids are optically active except glycine( its side chain is a hydrogen ato 2. amphoteric can act as an acid (proton donor) & as a base (proton acceptor ) 3.Zwitterion Possesses both a positive or negative ion Acidity is due to П electron delocalization. 4.Isoelectric Point (pl) The pH value at which zwitterion state exists at a maximum 5. ACID-BASE PROPERTY

plane polarized light shifted to the right

1.a. dextrorotatory (+)

plane polarized light shiftedto the left

1.b. levorotatory

IMPORTANCE OF pl:

1. Used in buffer systems 2. For separation & identification purposes - since each amino acid has its distinct pl 3. Show structural changes in globular CHON- the explanation of structures of biological reactions

All amino acids are optically active except nycin (its side chain is a hydrogen atom) Due to the presence of chiral asymmetric carbon Ability to rotate the plane polarized light in a polarimeter

optically active

(+) plane polarized light shifted to the right

dextrorotatory

(+)-plane colanzed light shifted to the left

levoratatory

Can act as an acid (protan donor) & as a base (proton acceptor

amphoterix

COOH

proton donor

NH2 -proton acceptor (base

proton acceptor (base

Possesses both a positive or negative ion Acidity is due to n electron delocalization. The OH bond in COOH weakens so it is readily easily given off. or lost as a proton and is accepted by the lone pair in NH3

zwitterion

The pH value at which zwittenon state exists at a maximum Amino acids & proteins assume a zero net charge Amino acids & proteins are least soluble (ppt form) No integration in an electric field

isolectric point

NEUTRAL OR STRAIGHT CHAIN AMINO ACIDS: (POLAR)

glycine alanine

Those which cannot be synthesized in the body Must be provided in the diet Primarily concerned with growth and maintenance of life

essential acids

Growing children require them in food But they are not essential for the adult individual

partially essential amino acid

Those which can be produced in the body

non essential/ dispensable amino acid

When a person is suffering from a moderate to severe chronic Glycine liness, person may lose the ability to manufacture enough non- essential amino acids and thus require supplementation Problems with digestion will also necessitate supplementation of "non-essential" amino acids. These amino acids are normally non-essential, but become essential during times of physiological stress Then these amino acids have to be taken in food or through supplements

conditionally amino acid

according to metabolism

a. purely ketogenjc b. ketogenic and glucogenic c. purely glucogenic

because it is converted to ketone bodies

purely ketogenic

are partially ketogenic and partially-glucogenic During metabolism, part of the carbon skeleton of these amino acids will enter the ketogenic pathway and the other part to glucogenic pathway

ketogenic and glucogenic

are purely glucogenic as they enter only into the glucogenic pathway which provide a substrate for gluconeogenesis

purely glucogenic

essential in spermatogenesis

argenine

has been widely studied for its effect in raising the general intelligence level of subnormal patient Used for the treatment of psychomotor and petit mal attacks

glutamic acid

Simplest amino acid and has is sweet in taste

glysine

(IAA) GABA glycine, B-alanine, Taurine

Inhibitory amino acid neurotransmitters

L-glutamate, L-Aspartate, L-cysteine, and L-Homocysteine

Excitatory amino acid neurotransmitters

Came from the Greek word "PROTEIOS meaning "pre-eminence or of first importance Most important macromolecule Organic compounds of high molecular weight (macromolecular made up of many amino acids)means of peptide linkages. Peptide bond is a covalent bond and can be dipeptide tripeptide, tetrapeptide, and oligopeptide Made up of C, H, O, N, usually S and traces of Fe, Cu, I. Mn, Zn etc Litmus paper red-blue
