FUNCTIONS OF CARBOHYDRATES
CARBOHYDRATES PROVIDES ENERGY TO THE BODY
45
FUNCTION OF FATS
THEY PROVIDES ENERGY TO BODY
46
FUNCTION OF CALCIUM
INCREASE THE BONES AND TEETH
47
PEPETIDE LINKAGE
A BOND BETWEEN COOH OF ONE a AMINO ACID WITH NH3 OF OTHER
48
PRIMARY STRUCTURE OF PROTEINS
PROTEINS ARE POLYPEPTIDE MEANS POLYMER OF a AMINO ACIDS AND THET HAVE A FIXED SEQUENCE THATS KNOWN AS PRIMARY STRUCTURE
49
DENATURATION OF PROTEINS
A PROCESS THAT CHNAGES THE PHYSCICAL AND BIOLOGICAL PROPERTIES OF PROTEAINS WITHOUT CHANGING ITS CHEMICAL PROPERTIES
50

54
WHAT ARE NUCLEIC ACIDS ??
NUCLEIC ACIDS ARE LONG CHAIN POLYMERS OF NUCLEOTIDES . THEY ARE ALSO CALLED POLYNUCLEOTIDES . NUCLEIC ACIDS ARE MAINLY OF 2 TYPES ; DEXOYRIBONUCLEIC ACID [DNA]AND RIBONUCLEIC [RNA]
55
FUNCTIONS OF NUCLIC ACIDS
1]DNA IS RESPONSIBLE FOR TRANSMISSION OF HEREDITARY EFFECT FROM MOTHER CELL TO DAUGHTER CELL 2]DNA AND RNA ARE RESPONSIBLE FOR SYNETHSIS OF ALL PROTEINS NEEDED FOR GROWTH AND MAINTANCE OF BODY
56
NUCLEOSIDE
A NUCLEOSIDE CONTAINS ONLY BASIC COMPONENT OF NUCLEIC ACIDS NAMELY A PENTOSE SUGAR AND A NITROGENOUS BASE
57
NUCELOTIDE
A NUCELOTIDE CONTAINS ALL THREE BASIC COMPONENTS OF NUCLEIC ACIDS NAMELY A PHOSPHORIC ACIDS GROUP , PENTOSE SUGAR , A NITROGENOUS BASE
58
WHAT IS ZWITTER ION ??
A zwitter ion is an ion that contains two functional groups. In simple terms, it is an ion possessing both positive and negative electrical charges. Therefore, zwitterions are mostly electrically neutral (the net formal charge is usually zero).
59
WHAT IS GLYCOGEN??
THE CARBOHYDRTES ARE STORED IN ANIMAL BODY AS GLYCOGENS . IT IS PRESENT IN BRAIN, MUSCLSES,LIVER . ENZYMES BREAK GLYCOGEN INTO GLUCOSE . GLYCOGEN IS MORE HIGHLY BRANCHED THAN STARCH
60
DEFINE POLYSACCHARIDES
Polysaccharides are major classes of biomolecules. They are long chains of carbohydrate molecules, composed of several smaller monosaccharides. These complex bio-macromolecules functions as an important source of energy in animal cell and form a structural component of a plant cell.
61
DEFINE DISACCHARIDES
A disaccharide (also called a double sugar ) is the sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose, and maltose. general formula of disaccharides is C12 H22 O11

1]NIGHT BLINDNESS 2]BERI BERI , LOSS OF APPETIDE 3]SCURVY 4]RICKETS 5]LOSS OF REPRODUCTIVE ABITLITY 6]COGULATION OF BLOOD
68
69
Define Testosterone 😁😁
Testosterone hormone is secreted by the gland tests and its function is to control organs in males
70
