Q.Explain the classification of proteins on the basis of
On the basis of shape, proteins are classified as fibrous proteins -- elongated, insoluble, structurally supportive molecules such as collagen -- or globular proteins -- compact, roughly spherical, generally soluble molecules such as haemoglobin. On the basis of function, proteins are grouped into several categories, including enzymatic proteins that catalyse reactions (e.g. amylase), hormonal proteins that act as chemical messengers (e.g. insulin), transport proteins that carry molecules through the body (e.g. haemoglobin, which carries oxygen), and defence proteins such as antibodies that neutralise foreign antigens. These two classification schemes are independent of one another: haemoglobin, for instance, is globular in shape and transport in function.
[!ANSWER]
Shape: fibrous (collagen) and globular (haemoglobin). Function: e.g. enzymatic (amylase), hormonal (insulin), transport (haemoglobin), defence (antibodies) -- any one function-example pair is acceptable.
