Biomolecules : Introduction and their roles in environment

Valine Lysine Glutamic acid Histidine Tryptophan Lysine Serine Leucine Tyrosine Methionine Tryptophan Phenylalanine Valine Histidine Lysine Aspartic acid Competitive inhibition is seen when a substrate competes with an enzyme for binding to an inhibitor protein Non-competitive inhibitors often bind to the enzyme irreversibly Competitive inhibition is seen when the substrate and the inhibitor compete for the active site on the enzyme Non-competitive inhibition of an enzyme can be overcome by adding large amount of substrate Uracil Cytosine Guanine Thymine Peptidase Amylase Sucrose Lipase Glycogen, sucrose and maltose Maltose, lactose and sucrose Glycogen, glucose and sucrose Glycogen, cellulose and starch. Proteins Fatty acids Volatile acid α < -keto acids. Phosphate and nitrogen base Pentose sugar and phosphate Pentose sugar, phosphate and nitrogen base Pentose sugar and nitrogen base. Lipid Protein Water Cellulose Ketose hexose sugar Pyronose pentose sugar Aldose hexose sugar Furanose pentose sugar.
