Structure of cellulose

Question 15

Strucutre of amino acids

Question 15

Classifical of amino acids + physical properties

Answer 15

essential and non-essential
colourless, crystalline solids that are water soluble and high melting
opticall active (excpt glycine) in d and l , mostly l (nh2 on left)

Question 16

Zwitter ion formation + nature

Answer 16

cooh losses proton, nh2 accepts proton , neutral overall

Question 17

Structure of proteins + explain peptide bond formation

Answer 17

reaction between 2 molecules of similar or diff amino acids through combination of amino groupd of 1 and carboxyl group of another and results in elimination of h2o molecule and formation of peptide bond (co=nh)

Question 18

Classification of proteins + explain

Answer 18

fibrous, globular

Question 19

Denaturation of protein

Answer 19

When a protein in its native form is subjected to change in temperature of chemical change (like ph), H-bonds are disturbed - globules unforl, helix gets uncoiled and protein losses its biological activity. This is denaturation of protein
1 deg -> intact ; 2 and 3 deg -> destroyed

Question 20

Use of enzymes

Answer 20

bio catalyst ; are globular protein ; reduces Ea barrier ( magnitude of activation energy)

Question 21

What are vitams + classification

Answer 21

vitamins are organic compounds required in small amounts to perform specific biological functions for normal maintenance of optimum growth & health of organism
fat soluble : A,D,E,K
water soluble : B , C

Question 22

What are nucleic acids + types

Question 23

RNA & DNA structure + bases

Question 24

Nucleoside & Nucleotide structure + Phosphodiester link
