Bonds involved in Protein Structure Proteins are the polymers of amino acids. Amino acids are joined together by a special type of covalent bond (peptide bond) to form linear structures called polypeptides. The polypeptides are then folded into specific structures to form the functional conformation of the protein. The folding of proteins into specific shapes … Read more
Classification of proteins: Proteins are important macromolecules of the cells, formed by the polymerization of amino acids according to the sequence of genetic code in the mRNA. Proteins are the mode of expression of the genetic information. They perform a variety of duties in the cells such as they act as the structural components of … Read more
What are xerophytes? Ø Xerophytes (xerophytic plants) are plants growing in dry habitats (xeric conditions) where the availability of water is very less. Xeric habitat are the places where water is NOT present in adequate quantity. Xerophytes are the characteristic plants of deserts or semi-deserts areas. Xerophytes can also grow in mesophytic conditions. The present post … Read more
Biological Importance of Water Biological importance of water: Water is the mother liquid of all forms of life. The essentiality of water for living systems is quite evident as without water, there is no life. No other substance on earth is abundant as water. All aspects of cell structure and functions are adapted to the … Read more
Physical and Chemical Properties of Water: Water is the most abundant substance in the living system. Water makes up about 70% or more of the weight of almost all organisms. The life has originated in remote past in the aqueous environment. The properties (both physical and chemical) of water enabled it as the ‘solvent of … Read more
