First 293 words of the document:

Polymers of amino acids joined by
peptide bonds. Structure
Zwitterions- +ve and -ve end
20 types 1 - Seq. of AA determined by
C-C only, (s)@ RT, high MP, C=C, (l) @ RT, low MP genetics code of DNA
Polypeptides
Amphoteric- act as acid and base 2 - Chain folds into Alpha- Helix or
(buffer when pH change) Beta- pleated sheet. (Bonds- H, S-S
Saturated Unsaturated and ionic)
Fibrous 3 - Further folded (bonds: H and S-
S (disulphide bridge between Cys
TRIGLYCERIDE- forms by and Cys)) 3D
condensation (ESTERIFICATION) Globular
1 gly + 3 fatty acids = 3 ester bonds
+ 3 H20 4 - 2 or mor Polypeptide chains Haemoglobin
Fatty Acids
Glycerol all made of
Join by condensation reaction =
peptide bond
Break by hydrolysis Storage in plants Storage in animals (muscles, liver
Lipid Bilayer ready for hydrolysis)
Amino Acids
LIPIDS Made of :
1.Amylose (straight helix) Branched polymer
2. Amylopectin (branched
Phospholipids made of monomers chain)
POTEINS
P + glycerol + 2 fatty acids Organic Molecules Starch Glycogen
ie Ribose in RNA GLU + GLU = MALTOSE
G3P
GLU + FRU = SUCROSE
GLU + GALA = LACTOSE
Triose (3C) Pentose (5C) Polysaccharides
CARBOHYDRATES made of
DNA- NUCLEIC ACIDS Monosaccharides join by condensation Disaccharides polymer of many monosacch.
= glycosidic bond joined by glycosididic bonds
Cellulose
Programs seq. of AA in protein
Regulates metabolism Hexose sugar (6C)
Unbranched chain, -OH chains and
GLUCOSE near chains form H bonds = stong
Polymers
Nucleotides
Phosphate
Nitrogenouse Base Pentose Sugar
Purine Pyrimidines
Ribose Deoxyribose
A and G T , U and C
RNA DNA
Single strand Double Strand
