BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The tertiary structure of a protein molecule encompasses the overall folding of polypeptide chains, where, if more than one chain is present, the chains are linked by covalent bonds-most often disulfide bonds (as in II).

Detailed explanation-2: -Tertiary structure is the next level up from the secondary structure, and is the particular three-dimensional arrangement of all the amino acids in a single polypeptide chain. This structure is usually conformational, native, and active, and is held together by multiple noncovalent interactions.

Detailed explanation-3: -The tertiary structure of a protein consists of the way a polypeptide is formed of a complex molecular shape. This is caused by R-group interactions such as ionic and hydrogen bonds, disulphide bridges, and hydrophobic & hydrophilic interactions.

Detailed explanation-4: -Important functional characteristics of proteins include their glass transition temperature, melting point, isoelectric point, molecular weight, secondary structure, solubility, surface hydrophobicity and emulsification [8]. These characteristics will establish their viability and best use in the food industry.

Detailed explanation-5: -Which of the following is an example of tertiary structure in a protein? polyalanine.
