Answer 1

T Globular proteins are spherical in shape and have tightly folded polypeptide chains. Hydrophobic groups of protein are on inside and hydrophilic groups are on the outside. This makes these. Proteins soluble in water 147. Insulin , Myoglobin, Hemoglobin all are globular proteins as they all are spherical. Option (D) is correct. 48] Glycerol is a compound having many hydroxy groups. (Three -OH groups are present J. Option (D) is correct. CH₂OH' CHOH CH2OH Myoglobin, insulin and Albumin in eggs are globular proteins. Collagen is a fibrous protein as it is long and narrow in structure. Option (D) is correct. 50%. Except Glycogen all are proteins. Option (c) is correct. Glycogen is the polymer of Glucose (carbohydrate) Rest are bolymers of amino acid (protuns.
